String Functoids Reference
Use String functoids to manipulate strings in standard ways.
Important
Because Microsoft BizTalk Server uses the underlying functionality of the .NET Framework, the results produced by some of the String functoids may vary from the equivalent functoids in earlier versions of BizTalk Server. For example, string lengths are counted in characters rather than in bytes, which can differ for character encodings that use more than one byte per character. In such cases, the calculated length of the string may differ from the apparent length of a displayed string. You should test your maps thoroughly to ensure that you are getting the results you expect.
For conceptual information about String functoids, see String Functoids.
The following table shows the functoids in the String category.
