again , VB.NET equivalent??[Resolved]

What's the equivalent of InStr that accepts (string, string) and return an integer specifying the start position of the first occurrence of one string within another. I had a look at Compare methods but it didn't help much .:confused:

VB Code:

Dim lNullPos As Integer
Dim sBuffer As String
 
lNullPos = InStr(sBuffer, vbNullChar)

Do you code in Visual Studio? The intellisense would list all of the available functions in the String class.

Dim strMyString as String = "Whatever"
Dim intIndex as Integer = strMyString.IndexOf("ate")

Not sure if that would solve it but I need something like the code I posted . I mean boths string variables will not be fixed , they're always change . So .....

VB Code:

Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click
        Dim x As String = "hello : ) How are you"
 
        MessageBox.Show(x.IndexOf("How"))
 
        'Or
        MessageBox.Show(InStr(x, "How") - 1)
 
    End Sub

Dim mytext As String = "abc"
Dim mypos As integer = InStr(mytext, "c", CompareMethod.Text)

In this case mypos will be set to 3. You can also use a compare method of binary.

was that what you were looking for?

I want to replace InStr function which for VB6 Code imported from VisualBasic namespace with pure .NET way . That's what I'm looking for . :D

btw , keep in mind that both strings are changeable . So the code dynamic_sysop and RichardAtherton are not applicable .

Thanks guys .

Never mind , figured it out

VB Code:

lNullPos = sBuffer.IndexOf(Nothing) + 1

Thanks both of you :)
