A few things here. First the error
Cannot implicitly convert type 'System.Threading.Tasks.Task' to string
This error is coming from the call to DataService.GetRequest(url)
. This method does return a string. Tt returns a Task where T is a string. There are many ways that you can use the result of this method. the first (and best/newest) is to await the call to the method.
string json = await DataService.GetResult(url);
Making this change requires you to add the async
keyboard to your method
public async static List<AccountModel> GetAccountList()
This is the new async/await pattern. Adding these words tells the compiler that the method cal is asynchronous. It allows you to make asynchronous calls but write code as if it is synchronous.
The other ways to call the method are to work the Task object directly.
// First is to use the Result property of the Task
// This is not recommended as it makes the call synchronous, and ties up the UI thread
string json = DataService.GetResult(url).Result;
// Next is to continue work after the Task completes.
DataService.GetResult(url).ContinueWith(t =>
{
string json = t.Result;
// other code here.
};
Now for the GetResult method. Using the async/await pattern requires you to return Task from methods. Even though the return type is Task, your code should return T. So as Krekkon mentioned, you should change the return line to
return responseBody;
Here is a great article about returning Task from an async method.
