DRAG DROP
You are developing an application that will include a method named GetDat
a. The GetData() method will retrieve several lines of data from a web service by using a
System.IO.StreamReader object.
You have the following requirements:
The GetData() method must return a string value that contains the first line of the response
from the web service.
The application must remain responsive while the GetData() method runs.
You need to implement the GetData() method.
How should you complete the relevant code? (To answer, drag the appropriate objects to the
correct locations in the answer area. Each object may be used once, more than once, or not
at all. You may need to drag the split bar between panes or scroll to view content.)
Answer: 
private async void GetData(WebResponse response)
{
var streamReader = new StreamReader(response.GetResponseStream());
= await streamReader.ReadLineAsync();
}

1. async
2. await
3. ReadLineAsync()
ReadToEndAsync() is not correct since only the first line of the response is required.
