How to determine if a string contains only a certain character?

Asked by sasllc in Microsoft Visual Basic.Net

We're developing in vb 2005 in the compact framework environment.  I need to know if there is a quick and easy way to determine whether a string is composed of nothing but a specified character, one or more times.  For example, if I'm testing a string to see if it contains all "t"s, then these values would be true:

t
tttt

but these would not be true:

ta
123tt

because they include characters other than "t".

Any good solution?
