Calling a form from a string in c#

Question

I have a Windows Application in C# and I need to call a Form whose name is saved into a string variable in run-time.

Like;

I already have the form; Login.cs

string formToCall = "Login"
Show(formToCall)

Is this possible ?

Answer 1

Have a look at Activator.CreateInstance(String, String):

Activator.CreateInstance("Namespace.Forms", "Login");

you can also use the Assembly class (in System.Reflection namespace):

Assembly.GetExecutingAssembly().CreateInstance("Login");

Answer 2

Using reflection:

//note: this assumes all your forms are located in the namespace "MyForms" in the current assembly.

string formToCall = "Login"
var type = Type.GetType("MyForms." + formtocall);
var form = Activator.CreateInstance(type) as Form;

if (form != null)
   form.Show();
