How to get return value from Task wait()-CodePudding

I have one async method which return value and I want to add wait to this task.

var return = Task.Run(() => SomeMethod(param1)).Wait();

How can I get return value from above this line.

CodePudding user response：

The typical method would be to just write

 var result = Task.Run(() => SomeMethod(param1)).Result;

This will block until the result becomes available. So it is equivalent to

var task = Task.Run(() => SomeMethod(param1));
task.Wait();
return task.Result;

Note that using .Result is generally not recommended. It will block the calling thread, so there is little point not just using var result = SomeMethod(param1). There is also the risk of deadlocks. If this is run on the UI thread, and SomeMethod uses .Invoke or something else that waits for the UI thread, then your program will deadlock.

var result = await Task.Run(() => SomeMethod(param1));
