I ussed this function and it worked.i named the not similar to forms

VB

Private Function GetFormByName2(ByVal formName As String) As Object
        Dim myasm As System.Reflection.Assembly = System.Reflection.Assembly.GetExecutingAssembly()

        Try
            Return myasm.CreateInstance(myasm.GetName.Name.Replace(" ", "_") & "." & formName)

        Catch ex As Exception
            Return Nothing
        End Try

    End Function

//on tree view event after select

GetFormByName2(e.Node.Name.ToString).show()

Why does it have to be one line ? It will be a long line. I believe you can use reflection to do this, but of course, you will write a lot of code if you want to also interact with this form in any way.

Of course, given that the forms in your app are known at design time, it would make more sense to write code that just checks the known values and branches to show the known forms.

Christian is of course correct. His suggestion would probably be the best way.

However if you do not have enormous numbers of Forms and you don't mind having them all in memory at the same time, you could use the TreeViewNode.Tag property to store the appropriate form for each node.

This[^] on MSDN, the example shows how you can do this.
