How many times have you written this to trim a trailing slash from a path:
if (myPath.EndsWith("\\")) /* or "/" in the case of a URI */
myPath = myPath.Substring(0, myPath.Length-1);
Next time, try this:
myPath = myPath.TrimEnd(new char[]{'\\', '/'});
In addition to String.TrimStart() and String.TrimEnd(), there is an overload on String.Trim() that accepts a character array. There are good examples of usage in the MSDN Library. Here are the links:
System.String Trim(char[]) TrimStart(char[]) TrimEnd(char[])
