如何从C#以异步模式调用Web服务

大家好


我只想以异步模式调用Web服务.
这样我的应用程序就不会等到结束发送邮件为止.一旦调用了Web服务，我的应用程序应继续显示成功发送邮件"，并且发送电子邮件应在后台运行.


任何人都可以提供代码示例.

这是同步模式下的代码:

Hi All


I just want to call a Web service in asynchronous mode.
So that my application will not wait for the completion of sending the mail till the end.Once i call the web service,my application should go on with "Successfully send mail" and the sending email should run in the background.


Can anyone give the code samples.

Here is the code in synchronous mode:

using System.Web.Services;

/// <summary>
/// Summary description for KlassAktMailService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
// [System.Web.Script.Services.ScriptService]
public class KlassAktMailService : System.Web.Services.WebService
{

    public KlassAktMailService()
    {

        //Uncomment the following line if using designed components 
        //InitializeComponent(); 
    }

    [WebMethod]
    public string Send_Email(string strEmailAddrTo, string strEmailAddrCC, string strSubject, string strBody, string strFileName)
    {
        EmailAlert NewMail = new EmailAlert();
        return NewMail.SendEmail(strEmailAddrTo, strEmailAddrCC, strSubject, strBody, strFileName);
    }
}

我想要异步模式的代码.



谢谢与问候
