无法通过APM扩展访问TAP中的非静态方法

Question

I'm new to this and I am trying to create a TAP-over-APM wrapper for the BeginConnect method for my Socket object

public static Task ConnectTaskAsync(this Socket socket, EndPoint endpoint)
{
    return TaskFactory.FromAsync(socket.BeginConnect, socket.EndConnect, endpoint, null);
}

However, I'm getting an error on the FromAsync method "Cannot access non-static method FromAsync " in static context.

How should my code be like?

Answer 1

As the error is trying to tell you, you need an instance of TaskFactory .

You can use the default singleton instance ( Task.Factory ), or you can create your own using one of its constructors.

Answer 2

You can call static methods inside none static methods but you cannot call non static method inside a static method.

So either change the FromAsync to be static or create an instance of it.
