C＃如何调试异步

Question

This question might me really easy, but I really don't understand how to do it.

I've created a class with multiple methods that call each other (first one does some logic and then calls the second one and so on) . All these methods are async due to await to POST and GET method from outside server.

I want to debug my work, to see how it works on each stage and where have I gone wrong, but I don't know how. I've tried calling the first function directly from the main function and add a break point, but got yield that "await" is missing, and after addi n "await" i'm getting yield that I need to make the method async, which contradict my purpose .

What can I do ?

    public static void Main(string[] args)
    {
        await LoadCampaignTempleteJSONAsync();
    }

All I want is to follow the process of LoadCampaignTempleteJSONAsync .

Answer 1

The simplest way to call async method from Main would be calling Result or GetAwaiter().GetResult() :

public static void Main(string[] args)
{
    LoadCampaignTempleteJSONAsync().Result;
    LoadCampaignTempleteJSONAsync().GetAwaiter().GetResult();
}

Also, starting from C# 7.1 you can make Main async:

public static async Task Main(string[] args)
{
    await LoadCampaignTempleteJSONAsync();
}

Please try the following

class Program
{
    static void Main(string[] args)
    {
        var p = new Program();
        p.Run();
    }

    private async void Run()
    {
        await LoadCampaignTempleteJSONAsync();
    }

    private static Task LoadCampaignTempleteJSONAsync()
    {
        //Put breakpoint here!
        throw new NotImplementedException();
    }
}

and put a breakpoint inside the LoadCampaignTempleteJSONAsync() this will hit the breakpoint
