Do you mean convert it to C#?

C#

Form frm = new Form();
string formName = "Form1";
formName = string.Format("{0}.{1}", [Assembly].GetEntryAssembly.GetName.Name, formName);
frm = [Assembly].GetEntryAssembly.CreateInstance(formName) as Form;
frm.Show();

Or more succinctly:

C#

string name = string.Format("{0}.Form1", [Assembly].GetEntryAssembly.GetName.Name);
Form frm = [Assembly].GetEntryAssembly.CreateInstance(formName) as Form;
frm.Show();

Solution 2

C#

string formName = "frmTestForm";
formName = Assembly.GetEntryAssembly().GetName().Name + "." + formName;
               
Type type = Type.GetType(formName);
Form form = (Form)Activator.CreateInstance(type);

form.StartPosition = FormStartPosition.CenterParent;
form.ShowDialog();

Please don't answer questions that are this old. It is unlikely that the OP is going to still be having issues with it. As well, there is an existing answer that is appropriate.
