Split string and rertieve value based on condition using C# and VB.Net in ASP.Net

Hi nauna,

Check this example. Now please take its reference and correct your code.

Code

C#

protected void Page_Load(object sender, EventArgs e)
{
    string data = "AdminReferal >> disone >> distwo >> disfive >> usertwo";
    Response.Write(SplitGetLastTwo(data, ">>"));
    Response.Write("<br/>");
    data = "AdminReferal >> disone";
    Response.Write(SplitGetLastTwo(data, ">>"));
    Response.Write("<br/>");
    data = "AdminReferal >> disone >> distwo";
    Response.Write(SplitGetLastTwo(data, ">>"));
}

private static string SplitGetLastTwo(string data, string separator)
{
    string[] options = new string[] { separator };
    string[] splitedData = data.Split(options, StringSplitOptions.None);
    string value = "";
    if (splitedData.Length >= 2)
    {
        value = splitedData[splitedData.Length - 2] + separator + splitedData[splitedData.Length - 1];
    }
    else
    {
        value = string.Join(separator, splitedData);
    }

    return value;
}

VB.Net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    Dim data As String = "AdminReferal >> disone >> distwo >> disfive >> usertwo"
    Response.Write(SplitGetLastTwo(data, ">>"))
    Response.Write("<br/>")
    data = "AdminReferal >> disone"
    Response.Write(SplitGetLastTwo(data, ">>"))
    Response.Write("<br/>")
    data = "AdminReferal >> disone >> distwo"
    Response.Write(SplitGetLastTwo(data, ">>"))
End Sub

Private Shared Function SplitGetLastTwo(ByVal data As String, ByVal separator As String) As String
    Dim options As String() = New String() {separator}
    Dim splitedData As String() = data.Split(options, StringSplitOptions.None)
    Dim value As String = ""
    If splitedData.Length >= 2 Then
        value = splitedData(splitedData.Length - 2) & separator & splitedData(splitedData.Length - 1)
    Else
        value = String.Join(separator, splitedData)
    End If

    Return value
End Function

Output

disfive >> usertwo

AdminReferal >> disone

disone >> distwo
