View 4 Repliesis there anyway i can remove part of a string? if i had this string here "REMOVETHISPART-KEEPTHISPART" in a listbox how can i just remove "REMOVETHISPART-"
View 6 RepliesFor removing trailing part is I use the code
str.substring(0,str.length -2)
Is there a better way? I especially dislike using str.length.
Edit I wanted the question to be as short and simple as possible and I supposed that I just overlooked some String method. I try to be more precise.
I need to remove given number of characters from the end of a string. I don't want to care what the characters are and I don't want to introduce a risk of removing more characters.
If the number is larger then string length let's there is an exception (the string should be validated earlier).
I don't have the problem especially with length, but with referencing a variable twice (imagine a function instead of a variable). I also don't like necessity of subtraction but it is only a personal preference.
The question is taged vb.net so there is vb.net code (should be in a module):
<System.Runtime.CompilerServices.Extension> _
Public Shared Function RemoveFromEnd(stringValue As String, removedCharacters As Integer) As String
Return stringValue.Substring(0, stringValue.Length - removedCharacters)
End Function
