Reverse a String

Apr 22nd, 2007

I'm having trouble reversing a string. Me thinks I've stared at this too long.

 Help with Code Tags 
 VB.NET Syntax (Toggle Plain Text) 
  Private Sub btnReverse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnReverse.Click
        Dim strOrgText As String
        Dim strRevText As String
        Dim array As Array
 
        strOrgText = Me.txtTheString.Text
        array = strOrgText.ToCharArray()
 
        strRevText = array.Reverse    'Here is my problem
 
        strRevText = Me.lblResult.Text
 
    End Sub
  Private Sub btnReverse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnReverse.Click
        Dim strOrgText As String
        Dim strRevText As String
        Dim array As Array

        strOrgText = Me.txtTheString.Text
        array = strOrgText.ToCharArray()

        strRevText = array.Reverse    'Here is my problem

        strRevText = Me.lblResult.Text

    End Sub

Thx

        Dim input As String = "abc"
        Dim output As String = ""
        Dim CharStr As New Char
        For Each CharStr In input
            output = CharStr & output
        Next
        MessageBox.Show(output)
        Dim input As String = "abc"
        Dim output As String = ""
        Dim CharStr As New Char
        For Each CharStr In input
            output = CharStr & output

VB.NET Syntax (Toggle Plain Text)
strRevText = array.Reverse    'Here is my problem
strRevText = array.Reverse 'Here is my problem

thats becouse array.Reverse needs an argument and the other thing it does not produce value so you can't assign it to strRevText

Good day!

Maybe this code will help you. Try this.

Dim StrongText as string
Dim ReverseText as string

StringText="This is a string"
ReverseText= StrReverse(StringText)

This will reverse the value of StringText variable.
