Auto increment Number from string contains text and number in C# and VB.Net

Hi ruben00000,

Here in this example i am making use of Regular Expression.

Please refer below code.

HTML

<asp:Label ID="lblMessage" runat="server"></asp:Label>

Code

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        string textId = "CORESNR02-1Mech";
        if (!string.IsNullOrEmpty(textId))
        {
            string id = Regex.Match(textId.Split('-')[1], @"\d+").Value;
            lblMessage.Text = string.Format("{0}-{1}Mech", textId.Split('-')[0], (Convert.ToInt32(id) + 1));
        }
    }
}

VB.Net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        Dim textId As String = "CORESNR02-1Mech"

        If Not String.IsNullOrEmpty(textId) Then
            Dim id As String = Regex.Match(textId.Split("-"c)(1), "\d+").Value
            lblMessage.Text = String.Format("{0}-{1}Mech", textId.Split("-"c)(0), (Convert.ToInt32(id) + 1))
        End If
    End If
End Sub
