Mandrill version 3 Ping() method

问题

In the previous version of Mandrill, I was using the following piece of code ( written in C# based on ASP.NET framework):

MandrillApi mapi = new MandrillApi(
            SettingsKeyInfoProvider.GetValue("MandrillAPIKey"),
            SettingsKeyInfoProvider.GetBoolValue("MandrillUseSSL"),
            SettingsKeyInfoProvider.GetIntValue("MandrillTimeout"));

// validate and respond
string pingResult = mapi.Ping();

if (pingResult.ToUpper().Contains("PONG!"))
    return mapi;

After updating the Mandrill version to 3 and how can I get the "PONG" message from Ping() method, previously the Ping() method had a return type string, but now in Mandrill version 3 the Ping() method has the return type as Task<string>. I tried debugging the code but not able to find the message as "PONG".

I tried to google and the possible solutions I found did not work.

Also I tried string pingResult = mapi.Ping().Result; which returns a string but it throws an exception.

Can anyone please help?

Edit: I am facing the deadlock in the following:

Without ConfigureAwait(false) getting the same issue. At this point as mentioned in above screenshot, the page loads infinitely and no result shows up.

回答1:

If the return type of any Method is Task<T> or Task you can await that method. This change was probably done so that if Ping takes a while (e.g if it times out) it wont be blocking the Thread for a long time.

To get the string, you can either await the method call:

string pingResult = await mapi.Ping();

But you can only do this in an async Context, so if the Method declaration is marked with async. Or, if your context is synchronous, you can do this:

string pingResult = mapi.Ping().GetAwaiter().GetResult();
