Trim last 4 characters from string?

Question

How can I trim MyString to be MyStr?

Thanks, google failed again :(

Answer 1

Rob's answer is mostly correct but the SubString solution will fail whenever the string has less than 4 characters in it. If the length goes past the end of the string an exception will be thrown. The following fixes that issue

Public Function TrimRight4Characters(ByVal str As String) As String
  If 4 > str.Length Then
    return str.SubString(4, str.Length-4)
  Else
    return str
  End if
End Function

Answer 2

YourString.Left(YourString.Length-4)

or:

YourString.Substring(0,YourString.Length-4) 

Answer 3

This is what I used in my program (VB.NET):

    Public Function TrimStr(str As String, charsToRemove As String)
        If str.EndsWith(charsToRemove) Then
            Return str.Substring(0, str.Length - charsToRemove.Length)
        Else
            Return str
        End If
    End Function

Usage:

Dim myStr As String = "hello world"
myStr = TrimStr(myStr, " world")

This is my first answer. Hope it helps someone. Feel free to downvote if you don't like this answer.

Answer 4

c#

string str = "MyString";
Console.WriteLine(str.Substring(0, str.Length - 3));

vb.net

dim str as string = "MyString"
Console.WriteLine(str.Substring(0, str.Length - 3))

vb.net (with VB6 style functions)

dim str as string = "MyString"
Console.WriteLine(Mid(str, 1, len(str) - 3))
