vb.net - Create a method call in .NET based on a string value

Question

Right now, I have code that looks something like this:

Private Sub ShowReport(ByVal reportName As String)
    Select Case reportName
        Case "Security"
            Me.ShowSecurityReport()
        Case "Configuration"
            Me.ShowConfigurationReport()
        Case "RoleUsers"
            Me.ShowRoleUsersReport()
        Case Else
            pnlMessage.Visible = True
            litMessage.Text = "The report name """ + reportName + """ is invalid."
    End Select
End Sub

Is there any way to create code that would use my method naming conventions to simplify things? Here's some pseudocode that describes what I'm looking for:

Private Sub ShowReport(ByVal reportName As String)
    Try
        Call("Show" + reportName + "Report")
    Catch ex As Exception
        'method not found
    End Try
End Sub

Answer 1

Type type = GetType();
MethodInfo method = type.GetMethod("Show"+reportName+"Report");
if (method != null)
{
    method.Invoke(this, null);
}

This is C#, should be easy enough to turn it into VB. If you need to pass parameter into the method, they can be added in the 2nd argument to Invoke.
