C#异步绑定数据实现方法

本文实例讲述了c#异步绑定数据实现方法。分享给大家供大家参考。具体如下：

using system;
using system.collections.generic;
using system.text;
using system.data.sqlclient;
using system.data;
using system.windows.forms;
namespace windowsapplication2
{
 public class asynccallbackopeartion
 {
  private static datagridview datagridview;
  public static void asynccallback(string connectionstring, string sql, datagridview dgv)
  {
   datagridview = dgv;
   connectionstring += ";asynchronous processing=true";
   sqlconnection conn = new sqlconnection(connectionstring);
   sqlcommand command = new sqlcommand(sql, conn);
   conn.open();
   command.beginexecutereader(new asynccallback(asynccallback), command);
  }
  static void asynccallback(iasyncresult ar)
  {
   if (ar.iscompleted)
   {
    sqlcommand com = (sqlcommand)ar.asyncstate;
    sqldatareader dr = com.endexecutereader(ar);
    datatable dt = new datatable();
    dt.load(dr);
    dr.close();
    if (datagridview.invokerequired)
    {
     updatedg ur = new updatedg(databin);
     datagridview.invoke(ur, dt);
    }
   }
  }
  delegate void updatedg(datatable dt);
  public static void databin(datatable dt)
  {
   datagridview.datasource = dt;
  }
 }
}

希望本文所述对大家的c#程序设计有所帮助。
