控件中如何调用windows Form中的Load事件呀

[cnjack]

我的控件中要刷新數據,需要重新執行windows Form的Load事件,該如何引用呀?

[cnjack]

各位,不是直接調用,是Form所屬的控件,其通過this.FindForm(),找到所屬Form,再如何調用Form的Load事件的問題

[patrickpan]

用委托。

这样做（再次调用Form_Load的响应函数）不好。

需要再次调用的代码，最好独立出来。比如以下代码，控件中要再次刷新数据，可以这样调用
(this.Parent as Form1).MyInitialization();

class Form1 : Form
{
   void Form1_Load(object sender, EventArgs e)
   {
      //...
      MyInitialization();
   }

   public void MyInitialization()
   {
      //刷新数据
   }
}

把load里的代码写成另外的方法,再调用.

[cnjack]

大哥,那樣,我上百个Form都得要去修改，如果可以直接调用控件所属Form的Load方法，可以少修改好多地方；如果需要，可以再手工修改。

如果load方法是public的可以这么掉

public void Form1_Load( object sender , EventArgs e )
        {
            MessageBox.Show( "test" );
        }

        private void button2_Click( object sender , EventArgs e )
        {
            object[] obj = new object[2];
            obj[0] = button2.FindForm();
            obj[1] = new EventArgs();
            button2.FindForm().GetType().GetMethod( "Form1_Load" ).Invoke( this , obj );
        }

[cnjack]

那这样看来，只有修改Form的Load事件的为Public的了，有其它的办法吗?

[zgke]

Form1_Load(null,null)?

[gsmlove]

用委托

[cnjack]

不知道哪位知道用反射呀？

[cnjack]

我倒是喜欢10楼的方法，可惜只能是公用的才行

[长沙三毛]

Form1_Load(this, EventArgs.Empty);

[GTX280]

直接调用Load事件函数就行

用反射直接调用即可
object[] obj=new object[2];
obj[0]=this.FindForm();
obj[1]=new EventArgs();
MethodBase b = this.FindForm().GetType().GetMethod(this.FindForm().Name + "_Load", BindingFlags.Instance | BindingFlags.NonPublic);
if(b!=null)
b.Invoke(this.FindForm(), obj);
可参考以下代码：
反射的查看类型信息:ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.VisualStudio.v80.chs/dv_fxadvance/html/7e7303a9-4064-4738-b4e7-b75974ed70d2.htm

下面的示例使用所有的反射 *Info 类以及 BindingFlags 来列出指定类的所有成员（构造函数、字段、属性、事件和方法），并将这些成员划分为静态和实例类别。
// This program lists all the members of the
// System.IO.BufferedStream class.
using System;
using System.IO;
using System.Reflection;

class ListMembers {
public static void Main(String[] args) {
// Specifies the class.
Type t = typeof (System.IO.BufferedStream);
Console.WriteLine ("Listing all the members (public and non public) of the {0} type", t);

// Lists static fields first.
FieldInfo [] fi = t.GetFields (BindingFlags.Static |
BindingFlags.NonPublic | BindingFlags.Public);
Console.WriteLine ("// Static Fields");
PrintMembers (fi);

// Static properties.
PropertyInfo [] pi = t.GetProperties (BindingFlags.Static |
BindingFlags.NonPublic | BindingFlags.Public);
Console.WriteLine ("// Static Properties");
PrintMembers (pi);

// Static events.
EventInfo [] ei = t.GetEvents (BindingFlags.Static |
BindingFlags.NonPublic | BindingFlags.Public);
Console.WriteLine ("// Static Events");
PrintMembers (ei);

// Static methods.
MethodInfo [] mi = t.GetMethods (BindingFlags.Static |
BindingFlags.NonPublic | BindingFlags.Public);
Console.WriteLine ("// Static Methods");
PrintMembers (mi);

// Constructors.
ConstructorInfo [] ci = t.GetConstructors (BindingFlags.Instance |
BindingFlags.NonPublic | BindingFlags.Public);
Console.WriteLine ("// Constructors");
PrintMembers (ci);

// Instance fields.
fi = t.GetFields (BindingFlags.Instance | BindingFlags.NonPublic |
BindingFlags.Public);
Console.WriteLine ("// Instance Fields");
PrintMembers (fi);

// Instance properites.
pi = t.GetProperties (BindingFlags.Instance | BindingFlags.NonPublic |
BindingFlags.Public);
Console.WriteLine ("// Instance Properties");
PrintMembers (pi);

// Instance events.
ei = t.GetEvents (BindingFlags.Instance | BindingFlags.NonPublic |
BindingFlags.Public);
Console.WriteLine ("// Instance Events");
PrintMembers (ei);

// Instance methods.
mi = t.GetMethods (BindingFlags.Instance | BindingFlags.NonPublic
| BindingFlags.Public);
Console.WriteLine ("// Instance Methods");
PrintMembers (mi);

Console.WriteLine ("\r\nPress ENTER to exit.");
Console.Read();
}

public static void PrintMembers (MemberInfo [] ms) {
foreach (MemberInfo m in ms) {
Console.WriteLine ("{0}{1}", " ", m);
}
Console.WriteLine();
}
