using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace WinInterfaceCallBackVs08 { class Class1 { public Class1() { new Action<string>((s) => { }).BeginInvoke("", null, null); new Action<string>(exSql).BeginInvoke("", null, null); } public void exSql(string sql) { } } }
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace WinInterfaceCallBackVs08 { class Class1 { public Class1() { new Action<string>((s) => { }).BeginInvoke("", null, null); } } }
大括号中写方法名,双引号中写sql语句 以上方法适合.net 4.0
如果是.net 1.1则用一下方法
private void button1_Click(object sender, System.EventArgs e) { BookingMgr.BookingMgr sms=new BookingMgr.BookingMgr(); //同样的实例化对象 sms.BeginRmkPnr(new AsyncCallback(MySMS),sms); //使用带Begin开头那个方法,要传一个方法进去(我这里叫MySMS) } //这个方法中实现真正的调用及结果! public static void MySMS(IAsyncResult iar) { BookingMgr.BookingMgr sms=new BookingMgr.BookingMgr(); //同样的实例化对象 string sSendRes=sms.RmkPnr("","",""); }
以上方法在.net1.1的B/S和C/S结构通用,在.net2.0的b/s结构也能用,但.net2.0的c/s结构下就用不了,可以用下面这种方法
private void test()
{
localhost.WebService service = new localhost.WebService();
service.HelloWorldCompleted += new localhost.HelloWorldCompletedEventHandler(service_hello);
service.HelloWorldAsync();
}
private void service_hello(object sender, localhost.HelloWorldCompletedEventArgs e)
{
if (e.Error == null)
MessageBox.Show(e.Result);
else
MessageBox.Show(e.Error.Message);
}
{
localhost.WebService service = new localhost.WebService();
service.HelloWorldCompleted += new localhost.HelloWorldCompletedEventHandler(service_hello);
service.HelloWorldAsync();
}
private void service_hello(object sender, localhost.HelloWorldCompletedEventArgs e)
{
if (e.Error == null)
MessageBox.Show(e.Result);
else
MessageBox.Show(e.Error.Message);
}
