[RESOLVED] Delete string split symbol

[bodylojohn]

Hello,

I have the following string in Cooridnates:

(0,0,11,11)#(1,1,22,334)#(34,54,55,66)

With the following code I delete the last coordinates:

strCoordinates = Coordinates.Split("#")
            strCoordinates(counter) = ""
            Coordinates = Join(strCoordinates, "#")
            TextBox1.Text = Coordinates

The coordinates now look like this:

(0,0,11,11)#(1,1,22,334)#

However they should look like this:

(0,0,11,11)#(1,1,22,334)

How do I get rid of the LAST "#"???

Thanks in advance guys

Don't use Split at all.

Dim myString As String = "(0,0,11,11)#(1,1,22,334)#(34,54,55,66)"
 
myString = myString.Substring(0, myString.LastIndexOf("#"c))

Note that if the string doesn't contain that character that code will throw an exception, so if you aren't already sure then you need to test it.

Thank you very very much,

That works perfect.

But now were still on the subject of strings .

Like you said I have to check for the "#" value in my string or otherwise I get an error message.

I tried the following:

If Coordinates Like "*#*" Then
  Coordinates = Coordinates.Substring(0, Coordinates.LastIndexOf("#"c))
Else
  Coordinates = ""
End If

But I still get the error message...

Dim myString As String = "Hello#"
        If myString.Contains("#") Then
            'Do stuff
        End If
