从Visual Studio 2010中的WCF异步调用返回值

Question

I want to get the value from a wcf async call.

public DateTime currentDateTime;
private void GetDateTime()
    {
        var client = new WcfClient();
        client.GetCurrentDateTimeCompleted -= ClientGetCurrentDateTimeCompleted;
        client.GetCurrentDateTimeCompleted += ClientGetCurrentDateTimeCompleted;
        client.GetCurrentDateTimeAsync();
    }

    private void ClientGetCurrentDateTimeCompleted(object sender, GetCurrentDateTimeCompletedEventArgs args)
    {
        try
        {
            if (args.Error == null && args.Result != null)
            {
                currentDateTime = args.Result;
            }
        }

To call this method. I use GetDateTime . My question is the code didn't reach the method at all in the debug mode. The result time is Date = {1/1/0001 12:00:00 AM} .

I know I call it synchronously. But how to get it in the debug model?

Answer 1

The easiest way is putting a breakpoint at the first line of the async method and pressing F5, the debugger should stop there and you can debug it.

See here.

Also MSDN has the document.
