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。
