Here you are :

StreamReader queueFile;
try
{
queueFile = File.OpenText(@"c:\Queue.txt");
this.txtQueue.Text = queueFile.ReadToEnd();
}
catch (Exception exc)
{
MessageBox.Show("File could not be read." + Environment.NewLine +
@"Please verify file C:\Queue.txt has" +
"has been created on you computer.");
}
finally
{
if (queueFile != null)
{
queueFile.Close();
}
}

Instant C# gives:

StreamReader queueFile = null;

try
{
queueFile = File.OpenText("c:\\Queue.txt");
this.txtQueue.Text = queueFile.ReadToEnd();
}
catch (Exception exc)
{
MessageBox.Show("File could not be read." + System.Environment.NewLine
+ "Please verify file C:\\Queue.txt has" + "has been created on you
computer.");
}
finally
{
if (! (queueFile == null))
{
queueFile.Close();
}
}

The other posters have given a literal conversion. A more idiomatic C#
version would be:

using (StreamWriter queueFile = File.OpenText(@"c:\Queue.txt"))
{
try
{
this.txtQueue.Text = queueFile.ReadToEnd();
}
catch (Exception e)
{
MessageBox.Show("File could not be read."+ Environment.NewLine+
@"Please verify file C:\Queue.txt has"+
"has been created on you computer.");
}
}

(This actually uses an extra try block, and calls queueFile.Dispose()
rather than queueFile.Close(), but is still easier to use, IMO.)
