Reverse a String

Expand Post »

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

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

Re: Reverse a String

Try this:

VB.NET Syntax (Toggle Plain Text)
        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
        Next
        MessageBox.Show(output)

Re: Reverse a String

Quote ...

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

Quote ...

VB.NET Syntax (Toggle Plain Text)
strRevText = Me.lblResult.Text
strRevText = Me.lblResult.Text

here is problem too , here u do not show the result !

after the correction this is ur code

(Toggle Plain Text)

Dim strOrgText As String
        Dim strRevText As [Char]()
        Dim array As Array

        strOrgText = Me.txtTheString.Text
        strRevText = strOrgText.ToCharArray
        array.Reverse(strRevText)   
        Me.lblResult.Text = strRevText

or u can use StrReverse function like this

VB.NET Syntax (Toggle Plain Text)
Me.lblResult.Text = StrReverse(Me.txtTheString.Text)
Me.lblResult.Text = StrReverse(Me.txtTheString.Text)

Re: Reverse a String

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.
