[RESOLVED] Count char occurance in str.

Guys,

How would I go about counting the occurance of a certain character in a given string?

Looking at the string.compare function but cant quite get my head around it.

Thanks
Bob

vb Code:

Dim str As String = "Hi--sdfsdfsdf--"
        MessageBox.Show(str.Split("-").Length)

You could loop through each character and check:

vb Code:

Dim myString As String = "howmanytimesdoesthelettereoccur"
Dim myCOunt As Integer = 0
 
        For Each ch As Char In myString
            If ch = "e" Then myCOunt += 1
        Next
 
        MessageBox.Show(myCOunt.ToString)

You could use something like this, be aware that it'll be case sensitive.

vb Code:

Public Function CharCount(ByVal c As Char, ByVal str As String) As Integer
 
        Dim intCount As Integer
 
        For Each character As Char In str
            If character = c Then
                intCount += 1
            End If
        Next
  Return intCount
    End Function

This worked for me

vb Code:

Dim str As String = "Hisdf--sddd---fsdf"
        Dim ncount As Integer = str.Split("-").Length
        If ncount = 0 Then
            Console.WriteLine("0 matches")
        Else
            Console.WriteLine(String.Concat(ncount - 1, " matches found"))
        End If

the str.split worked just fine for me.

Thanks
