Initialize StrPath to the empty string ("") and declare it outside your loop. You may also want to consider using a StringBuilder since Strings in c# are immutable.

I agree with Mitch Wheat, but you could solve your current problem initializating StrPath

string StrPath = string.Empty;

And as other people say, declare StrPath outside of the loop.

From MSDN

The C# compiler does not allow the use of uninitialized variables. If the compiler detects the use of a variable that might not have been initialized, it generates CS0165.

Use new to create an instance of an object or assign a value.
