反射的问题

[huangboxi]

有一类库class1,命名空间class1,里面有几个FORM: Form1,Form2....编译出来的为class.dll,我想通过反射调用class1下的Form1的show(),代码如下:

Assembly assembly = Assembly.LoadFrom("class1.dll");
Type type = assembly.GetType("class1.Form1");
Control instance = (Control)assembly.CreateInstance(type.ToString());
MethodInfo method;

method = type.GetMethod("show", BindingFlags.Public |
BindingFlags.Instance,
null,
CallingConventions.Any,
new Type[] ,
null
);
method.Invoke((object)instance);

method = null;

运行提示:未将对象引用设置到对象的实例。
经跟踪method为null
请问是什么问题?如何解决?

默认是大小写相关：

method = typeof(Form).GetMethod("Show", BindingFlags.Public |
BindingFlags.Instance,
null,
CallingConventions.Any,
Type.EmptyTypes,
null
);

        }

        private void button1_Click(object sender, EventArgs e)
        {
            Assembly assembly = Assembly.LoadFrom(Application.ExecutablePath);
            Type type = assembly.GetType("WindowsApplication5.Form1");
            Form F = (Form)Activator.CreateInstance(type);
            F.Show(); 
        }
    }
}
