Delegate function error

I have following code. dont have any clue why I am getting this error - Delegate Function doesnot take 1 arguments.

I am implementing a global Response handler which will be called by saveral requests.

Here is the HandleResponse function:

Response<T> HandleResponse<T>(Func<Response<T>> func)
{
    try
    {
        Response <T> response = func();
        if(response != null)
        {
            return response;
        }
        else
        {
            //display response.message
            return default(Response<T>);
        }
    }
    catch(ConnectionException e)
    {
        // func = e.Message.ToString();
        Console.WriteLine(e.Message);
        return default(Response<T>);
    }
}

And here is my Calling Function: 

Request.MyRequest request = new 
Request.MyRequest()
{
     param1= comment, param2 = users
};

SomeResponse response = HandleResponse<SomeResponse>(x => client.DoRequest(request, revision.Name, revision.RevisionNumber));

I am a C++ developer and very new to C#. I am not sure why I am getting this error. Please someone explain.

Thanks in advance.

By using x => client.DoRequest() you are calling the delegate with 1 Parameter (the x before =>).

But your delegate has no parameters so you have to call it like this () => client.DoRequest()
