YourString.Left(YourString.Length-4)
or:
或者：
YourString.Substring(0,YourString.Length-4)
回答by JaredPar
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
Rob 的回答大部分是正确的，但是只要字符串中的字符少于 4 个，SubString 解决方案就会失败。如果长度超过字符串的末尾，将抛出异常。以下解决了该问题
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

This is what I used in my program (VB.NET):
这是我在我的程序（VB.NET）中使用的：
Public Function TrimStr(str As String, charsToRemove As String)
If str.EndsWith(charsToRemove) Then
Return str.Substring(0, str.Length - charsToRemove.Length)

Return str
End If
End Function
Usage:
