Question

I try to replace the file name which contains “TEMPDOCUMENTLIBRARY” with “SHAREDDOCS” in the
docs (Typed Dataset). But somehow it does not replace it at all.
What’s wrong ?

for (int index = 0; index < docs.Document.Rows.Count; index++)
{
    if (docs.Document[index].FileName.Contains("TEMPDOCUMENTLIBRARY"))
    {
         docs.Document[index].BeginEdit();
         docs.Document[index].FileName.Replace("TEMPDOCUMENTLIBRARY", "SHAREDDOCS");
         docs.Document[index].EndEdit();
    }
}

Strings are immutable (meaning that the value of a given string never changes). Functions like Substring and Replace return new strings that represent the original string with the desired operations performed.

In order to achieve what you want, you need this:

docs.Document[index].FileName = 
      docs.Document[index].FileName.Replace("TEMPDOCUMENTLIBRARY", "SHAREDDOCS");
