Get UserID of the user using ASP.NET Membership

Retreiving the UserId for a user while using the ASP.NET Login controls is very simple, yet it still is one of the most frequently asked questions on the forums. Here's how to do so:

C#

    protected void Page_Load(object sender, EventArgs e)

    {

        System.Web.Security.MembershipUser mu = System.Web.Security.Membership.GetUser();

        string strUsrId = mu.ProviderUserKey.ToString();       

    }

VB.NET

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

        Dim mu As System.Web.Security.MembershipUser = System.Web.Security.Membership.GetUser()

        Dim strUsrId As String = mu.ProviderUserKey.ToString()

    End Sub
