Question

In the following code example,will filestream and streamreader get disposed or will they create memory leaks? Is it possible to code this function without causing memory leaks?

  string ReadFile(string strPath)
     {
         using (FileStream fstream = new FileStream(strPath, FileMode.Open))
         {
             using (StreamReader sreader = new StreamReader(fstream))
             {
                return sreader.ReadToEnd().ToString(); //NOTE ITS RETURNED HERE...SO CAN IT GET DISPOSED AFTER THIS LINE?
             }
         }
     }

Thanks

Answer 1

using directive means:

try
{
var iDisposable = new IDisposable();
//using iDisposable...
}
finally
{
//here IDisposable's dispose
}

So yes both fstream and sreader will be disposed.
