复制代码 代码如下:

//设置为后台线程

Thread th = new Thread(delegate() {

append();

});

th.IsBackground = true;

th.Start();

//在append方法里面需要调用前台控件

public void append(){

// ... 业务处理

this.Invoke(new flushMessage(showMessage), new object[] { row["Code"].ToString(), res });

}

//委托flushMessage和方法showMessage签名必须一致

private delegate void flushMessage(String id, String res);

private void showMessage(String id,String res)

{

if (res == "true")

{

txtMsg.Text += "tttt" + id + "tttt导入成功rn";

}

else

{

txtMsg.Text += "tttt" + id + "ttttt导入失败rn";

}

}
