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。
