网络上资源很多不全面，自己在开发的时候走了不少弯路，在这里整理了最全面的google全套开发，com交互，web端交互。封装好了各种模块功能。 直接就可以调用。
第一种方式：调用comapi实现调用google地球
1、安装googleearth客户端。传送门：https://pan.baidu.com/s/1xi3fwciy3jt6t5xbypqpcg 提取码：0l7u
2、添加引用using earthlib;如果找不到此dll，到googleearth的安装目录下寻找后添加到引用即可。
3、添加预定义的方法到项目中，后续获取窗口句柄，以及设置窗口的时候会调用其中的一些方法。
class nativemethods
{
[dllimport("user32.dll", charset = charset.auto, setlasterror = true)]
public static extern bool setwindowpos(intptr hwnd, intptr hwndinsertafter, int x, int y, int cx, int cy, uint32 uflags);
[dllimport("user32.dll", charset = charset.auto)]
public static extern intptr postmessage(int hwnd, int msg, int wparam, int lparam);
#region 预定义
public static readonly intptr hwnd_bottom = new intptr(1);
public static readonly intptr hwnd_notopmost = new intptr(-2);
public static readonly intptr hwnd_top = new intptr(0);
public static readonly intptr hwnd_topmost = new intptr(-1);
public static readonly uint32 swp_nosize = 1;
public static readonly uint32 swp_nomove = 2;
public static readonly uint32 swp_nozorder = 4;
public static readonly uint32 swp_noredraw = 8;
public static readonly uint32 swp_noactivate = 16;
public static readonly uint32 swp_framechanged = 32;
public static readonly uint32 swp_showwindow = 64;
public static readonly uint32 swp_hidewindow = 128;
public static readonly uint32 swp_nocopybits = 256;
public static readonly uint32 swp_noownerzorder = 512;
public static readonly uint32 swp_nosendchanging = 1024;
#endregion
public delegate int enumwindowsproc(intptr hwnd, int lparam);
[dllimport("user32", charset = charset.auto)]
public extern static intptr getparent(intptr hwnd);
[dllimport("user32", charset = charset.auto)]
public extern static bool movewindow(intptr hwnd, int x, int y, int nwidth, int nheight, bool brepaint);
[dllimport("user32", charset = charset.auto)]
public extern static intptr setparent(intptr hwndchild, intptr hwndnewparent);
[dllimport("user32.dll", exactspelling = true, charset = charset.auto)]
public static extern intptr getwindow(intptr hwnd, int ucmd);
public static int gw_child = 5;
public static int gw_hwndnext = 2;
}
4、定义变量
private bool isgestart = false;//ge是否开启
private applicationgeclass geapp;
/// <summary>
/// 用来关闭googleearth的消息定义
/// </summary>
static readonly int32 wm_quit = 0x0012;
private intptr gehwnd = (intptr)5;
private intptr gehrender = (intptr)5;
private intptr geparenthrender = (intptr)5;
5、做完上面的工作后，开始初始化谷歌地球。将下列代码放入自己定义的方法中即可。
try
{
if (!this.designmode)
{
geapp = new applicationgeclass();
gehwnd = (intptr)geapp.getmainhwnd();
//隐藏googleearth主窗口
nativemethods.setwindowpos(gehwnd, nativemethods.hwnd_bottom, 0, 0, 0, 0, nativemethods.swp_nosize + nativemethods.swp_hidewindow);
gehrender = (intptr)geapp.getrenderhwnd();
geparenthrender = (intptr)nativemethods.getparent(gehrender);
//将渲染窗口嵌入到主窗体
nativemethods.movewindow(gehrender, 0, 0, this.panelex_google.size.width, this.panelex_google.size.height, true);
nativemethods.setparent(gehrender, this.panelex_google.handle);
isgestart = true;
}
}
catch (exception ex)
{
isgestart = false;
thread.sleep(1000);
}
6、以上代码可加载谷歌地球，并且释放资源，程序运行如图：
第一种方式实质上是启动googleearth客户端，并获取窗口句柄，再将窗口显示的自己定义的控件下面，此种方法也可以实现需求，但是经过测试，此方法存在两大弊端。第一，在启动谷歌地球的时候将占用大量的cpu资源。第二、在释放谷歌地球的时候时候，可能会释放失败，无法关闭googleearth此时也将占用大量的cpu。基于以上弊端所以采用第二种方式。webroswer调用js。
2、重点：干货。
c#使用geplugin插件,webroswer与js交互，实现web端的googleearth体验。并且加载kml，加载三维模型dae，加载路径，电子围栏。各种功能已封装。调用即可使用。
1、下载geplugin 传送门：
链接：https://pan.baidu.com/s/1e_elo_x0klhffgnzbboa6w
提取码：687b
2、使用geplugin相对于comapi要较为复杂。但是性能最优。下载封装好的文件，单独的exe，放在程序项目文件中，启动这个文件，在程序中调用一个方法即可加载google地球到webroswer。因为这个文件有公司logo。所以不便发布于此，有想要的可以私信我。单独发送。谨记：此文件只供学习使用，交流心得，不得用于任何商业行为。
3、下面开始正式的编码。如果下载了exe的文件，并且打开后，执行此段代码，谷歌地球将被加载完成。获取的硬盘id以及cpu序列号，将此数据传递到封装好的服务中。防止别的浏览器直接输入网址浏览。安全校验使用。
并且将你的form设置成对com可见
[comvisible(true)]
public partial class analysisform : form
private cassinidev.server _server1;
private bool iswebserverstarted = false;
public string webserver_path;
private void navigateanaform_shown() { string plugin_url_local; string plugin_url_reload; //googleearth延时加载的线程 //在程序启动时使用单独的线程来加载webbroswer控件中的ge地图，以免出现主界面加载时卡顿的现象 thread gelazyloadingthread = new system.threading.thread(new system.threading.threadstart(delegate () { //thread.sleep(50); //记录系统中现有的geplugin线程 process[] listexistedgepluginprocess = process.getprocessesbyname("geplugin"); this.begininvoke( new action(() => { plugin_url_local = "http://127.0.0.1:9809/map.asp?px1=" + getcpuid() + "&px2=" + getdiskid(); plugin_url_reload = "http://127.0.0.1:9808/reload.html"; this.webbrowserge.objectforscripting = this; this.webbrowserge.scripterrorssuppressed = false ; //_server = new cassinidev.server(9630, "/", webserver_path, //"g:\\desktop\\1111\\bin\\debug\\navfiles", // system.net.ipaddress.parse("127.0.0.1"), "", false, true); //http://127.0.0.1:9809/map.asp?px1=178bfbff00810f10&px2=gloway stk720gs3-s7 //http://192.168.0.196:9808/map.asp?px1=bfebfbff000906e9&px2=sandisk cruzer glide 3.0 usb device this.webbrowserge.navigate(plugin_url_local); this.webbrowserge.visible = true; } )); })); //启动googleearth装载的线程 gelazyloadingthread.setapartmentstate(apartmentstate.sta); gelazyloadingthread.start(); }
private string getdiskid()
{
try
{
//获取硬盘id
string hdid = " ";
managementclass mc = new managementclass("win32_diskdrive");
managementobjectcollection moc = mc.getinstances();
foreach (managementobject mo in moc)
{
hdid = (string)mo.properties["model"].value;
}
moc = null;
mc = null;
return hdid;
}
catch
{
return "unknown";
}
finally
{
}
}
private string getcpuid()
{
try
{
//获取cpu序列号代码
string cpuinfo = " ";//cpu序列号
managementclass mc = new managementclass("win32_processor");
managementobjectcollection moc = mc.getinstances();
foreach (managementobject mo in moc)
{
cpuinfo = mo.properties["processorid"].value.tostring();
}
moc = null;
mc = null;
return cpuinfo;
}
catch
{
return "unknown";
}
finally
{
}
}
4、此时地图即可加载完成，万水千山，踏出第一步。但是此时无法向谷歌地球添加kml或者三维模型。和一些其他的操作。如果要加载kml文件。继续往下看。
5、此时启动web容器 ，先添加引用 cassinidev4-lib；找不到又不想下载？ 传送门来了：
链接：https://pan.baidu.com/s/1lozd7plvagg3nstmeeub0g
提取码：oymj
/// <summary>
/// 启动web容器服务
/// </summary>
public void start_webserver()
{
webserver_path = string.concat(new object[] { directory.getcurrentdirectory(), path.directoryseparatorchar, "3dview" });
_server1 = new cassinidev.server(9630, "/", webserver_path,
system.net.ipaddress.parse("127.0.0.1"), "", false, true);
if (!iswebserverstarted)
{
try
{
_server1.start();
iswebserverstarted = true;
messagebox.show("web 服务已经打开！");
}
catch (exception ex)
{
messagebox.show( "服务打开失败！", "信息提示", messageboxbuttons.ok, messageboxicon.error);
_server1.dispose();
return;
}
/*
try
{
_server2.start();
iswebserverstarted = true;
}
catch (exception ex)
{
xtramessagebox.show(program.devexpressdarkskin, "gbq服务2打开失败！", "信息提示", messageboxbuttons.ok, messageboxicon.error);
_server2.dispose();
return;
}
*/
}
else
{
try
{
_server1.shutdown();
iswebserverstarted = false;
}
catch (exception ex)
{
messagebox.show( "服务关闭失败！", "信息提示", messageboxbuttons.ok, messageboxicon.error);
_server1.dispose();
//return;
}
try
{
_server1.start();
iswebserverstarted = true;
}
catch (exception ex)
{
messagebox.show( "服务打开失败！", "信息提示", messageboxbuttons.ok, messageboxicon.error);
_server1.dispose();
return;
}
}
}
6、此时小伙伴要问，为什么要启动一个web服务，不要着急，往下看。加载kml文件。
webbrowserge.document.invokescript("importlidarkmlfilebyurl", new object[] { "http://127.0.0.1:9630/3dmap/zouhang1.kml",true });
是不是很神奇，只需要一行代码，你的kml文件，或者kml文件中带有有三维模型的文件，即可被加载成功，因为程序已经完全封装了你所需要的功能。
解析上一个疑惑，为什么要启动一个web服务，因为invokescprit加载文件的时候需要以网址的形式加载，所以启动一个web服务器，并设置好root目录，将你的kml文件放置到root目录下即可。
7、你以为此时kml文件就可以加载成功了？成功的道路总是充满坎坷的。此时的你加载kml的时候，应该是看不到任何反应的。因为我当初在这个地方踩了很多的坑。你们很幸运，不需要在这里挣扎。记录一下。分享给你们。
///重要重要重要
public string getmapserverandlag_callback() { return "7,1,18"; }
多么简单的一个方法，但是没有他你什么也做不了。这个是地图加载后的回调方法。务必加上。用于给层级赋值。
下面还有几个方法，分享给你门，可有可无。
//加载失败后的回调函数
public void jsinitfailurecallback_(string error){
}
//加载成功后的回调函数
public void gesuccessloadedcallback_()
{
}
8、经过以上的努力你已经达成了目标的80%了。你所想要的功能已经基本实现。
另外一些其他的加载方法在这里附上
webbrowserge.document.invokescript("importgooglemapkmlfilebyurl", new object[] { "http://127.0.0.1:9630/3dmap/ditu.kml" });
webbrowserge.document.invokescript("importlidarkmlfilebyurl", new object[] { "http://127.0.0.1:9630/3dmap/zouhang1.kml",true });
webbrowserge.document.invokescript("importremarkkmlfilebyurl", new object[] { "http://127.0.0.1:9630/3dmap/1111.kml" });
webbrowserge.document.invokescript("importdrawkmlfilebyurl", new object[] { "http://127.0.0.1:9630/3dmap/1111.kml" });
webbrowserge.document.invokescript("importlidarkmlfilebyurl", new object[] { "http://127.0.0.1:9630/3dmap/1111.kml", true });
webbrowserge.document.invokescript("importdrawkmlfilebyurl", new object[] { "http://192.168.1.196:9630/3dpaint/kmldrawings/1111.kml", true });
webbrowserge.document.invokescript("searchlocation_e", new object[] { 38, 117 });
webbrowserge.document.invokescript("importlidarkmlfilebyurl", new object[] { "http://127.0.0.1:9630/3dmap/111.kml" });
webbrowserge.document.invokescript("getgekml_e");
webbrowserge.document.invokescript("setmaplayersstatus", new object[] { false, false, false, false, false, false, false, false, false, false, false, false });
非常简单，可自己摸索。
9、上图
到这里就结束了？不存在的。技术用于之境。下面分享给大家，如何将二维高德地图蒙皮到三维谷歌球体上。拭目以待。
10、加载高德地图到谷歌地球上。实现谷歌地球与高德地图之间的切换。
首先。需要下载两个坐标转换文件。传送门：
