Is there a difference between using the Visual Basic (VB.NET) Strings.Trim(String) method:
Dim myString As String = " myString "
myString = Trim(myString)
and the .NET String.Trim method:
Dim myString As String = " myString "
myString = myString.Trim()
Yes, the results of these two methods can be different. The first Strings.Trim(String) method -- Trim(myString) -- trims only spaces off the leading and trailing parts of the string, not tabs or other whitespace characters. The second String.Trim method -- myString.Trim() -- trims all whitespace (including tabs, carriage returns, linefeeds ... any character for which IsWhiteSpace(char) returns true) off the leading and trailing parts of the string.
The differences can be gleaned from the documentation,
