.NET Framework Task Parallel Library (TPL) Task: Returning a value
Example
Task that return a value has return type of Task< TResult > where TResult is the type of value that needs to be returned. You can query the outcome of a Task by its Result property.
Task<int> t = Task.Run(() =>
{
int sum = 0;
for(int i = 0; i < 500; i++)
sum += i;
return sum;
});
Console.WriteLine(t.Result); // Outuput 124750
If the Task execute asynchronously than awaiting the Task returns it's result.
public async Task DoSomeWork()
{
WebClient client = new WebClient();
// Because the task is awaited, result of the task is assigned to response
string response = await client.DownloadStringTaskAsync("http://somedomain.com");
}
