string strFromName="Form1";
Type type = Type.GetType(strFromName); // Null reference is coming here
Form form = (Form)Activator.CreateInstance(type);

Answer 1

从程序集中获取所有类型，并在获得instatnce类型后，通过名称将实例与字符串“Form1”进行比较

Answer 2

You have to supply the fully qualified name of the form ("TopNamespace.SubNameSpace.Form1") or if the form class is residing in an Assembly other than the calling you have to supply an AssemblyQualifiedName ("TopNamespace.SubNameSpace.Form1,MyAssembly").

See the Type.GetType documentation for the details.
