Use below:

    private Type[] GetTypesInNamespace(Assembly assembly, string nameSpace)
            {
                return assembly.GetTypes().Where(t => String.Equals(t.Namespace, nameSpace, StringComparison.Ordinal)).ToArray();
            }

            private void Form1_Load(object sender, EventArgs e)
            {
//Get all types
                Type[] typelist = GetTypesInNamespace(Assembly.GetExecutingAssembly(), "loopClasses");
                for (int i = 0; i < typelist.Length; i++)
                {//Loop on them 
                    if (typelist[i].BaseType == typeof(System.Windows.Forms.Form) && typelist[i].Name == textbox.text)
                    {//if windows form and the name is match

//Create Instance and show it
                        Form tmp =(Form) Activator.CreateInstance(typelist[i]);
                        //MessageBox.Show(typelist[i].Name);
                        tmp.Show();
                    }
                }

            }
