how to find the number of occurrences of a substring within a string vb.net

Question

I have a string (for example: \"Hello there. My name is John. I work very hard. Hello there!\") and I am trying to find the number of occurrences of the string

Answer 1

I used this in Vbscript, You can convert the same to VB.net as well

Dim str, strToFind
str = "sdfsdf:sdsdgs::"
strToFind = ":"

MsgBox GetNoOfOccurranceOf( strToFind, str)

Function GetNoOfOccurranceOf(ByVal subStringToFind As String, ByVal strReference As String)
    Dim iTotalLength, newString, iTotalOccCount
    iTotalLength = Len(strReference)
    newString = Replace(strReference, subStringToFind, "")
    iTotalOccCount = iTotalLength - Len(newString)
    GetNoOfOccurranceOf = iTotalOccCount
End Function
