>>I don't know whether they have added any functions since VS2005 into .NET but for me I had a job to do not spend my time working out all the extra code. So I used the toolkit. So if you find you are having to resort to typing in multiple lines of code and build your own missing functions, then why not use the pre built functions already in the toolkit. This function alone is a ratio of 30 lines to 0.

That is what we have done. We have an extensions class that has numerous methods that extend the string class.

There is a nice little and simple example at c-sharpcorner for this to get them started:
