通过反射将类的字符串生成对应的类

public Form GetInstance<Form>(string nameSpace, string className, object[] parameters)
        {
            //命名空间.类名
            string fullName = nameSpace + "." + className;
            object ect = System.Reflection.Assembly.GetExecutingAssembly().CreateInstance(fullName, true, System.Reflection.BindingFlags.Default, null, parameters, null, null);
            return (Form)ect;
        }
