Use a SubString or a indexof?

Question

Hi, 

I have a text label, split half-and-half with a "/".

This is an example:

label1.text = "I like dogs/I like cats"	

This will not be the same text (and not the same text length) every times. I need to delete everything before the "/" with only a button. (for example, delete "I like dogs")

I already tried to make a SubString, and a indexOf, but it didn't work... 

I realy need help,

Thank you,

Answer 2

Dim myString As String = "I like dogs/I like cats"
Dim newString As String

newString = myString.Substring(myString.IndexOf("/") + 1)

Something like that.

Best regards,

I found this code in some forums, but they didn't work..

And the label1.text was: "I like dogs/I like cats"

        Dim s As String = Label1.Text
        Dim i As Integer = s.IndexOf("/"c)
        Do While (i <> -1)
            Label2.Text = (s.Substring(i))
            i = s.IndexOf("/"c, i + 1)
        Loop
        Label2.Text = i

and also try this: 

        Dim s As String = label1.text

        Dim i As Integer = s.IndexOf("/"c)

        Dim part As String = s.Substring(i)
        Label2.Text = part

Label2 should be the result.  (I should get: "I like cats")

Answer 4

You're almost there. In the second version use i+1 instead of only i. As the index of the "/" is in i, the part after it is starts at i + 1.

Answer 5

Ok this is good! Thank you!

But now, if I want to only keep "I like dogs" and delete "/I like cats"

Is it possible?

Hi Dominic,

sure, then use

Dim part As String = s.Substring(0, i)
Label2.Text = part
