File Manipulation in C#

Question

How do I check if the following statement in my C# executed correctly?

StreamReader sr = new StreamReader(Path_To_File);

Answer 1

If it didn't throw an exception, it executed correctly. If it throws an exception, it's reasonable to expect the cosntructor to tidy up after itself. Otherwise, it'll be up to you to call Dispose on it when you're finished, to release the associated resources. As others answers have said, you almost certainly want to use a using statement to accomplish this.

You might also want to use File.OpenText instead:

using (TextReader reader = File.OpenText(fileName))
{
}

I only usually use the StreamReader constructor when I need to pass in different options (which is pretty rarely).
