methodsdisposestreamreaderusing

is dispose need for using()?

using (StreamReader streamReader = new StreamReader((Stream)cryptoStream))
{
    return streamReader.ReadToEnd();
}

Does the using method dispose automatically for streamReader?

Or do I have to manually dispose of streamReader?

Solution

  • The using statement will automatically call Dispose when the variable goes out of scope.

    Basically:

    using (var streamReader = new StreamReader())
{
    return streamReader.ReadToEnd();
}

    is equivalent to:

    var streamReader = new StreamReader()
try 
{
   return streamReader.ReadToEnd(); 
}
finally 
{
   streamReader.Dispose();
}
