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：
?| 12345678910111213141516171819202122232425262728293031323334353637383940414243 | 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。
