用Reflector反编译 Mobile Winform程序

用Reflector反编译 Mobile Winform程序

作者:顾恩礼

一、        准备工具

A.        Reflector工具:

 

B.        ResGen.exe工具(C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin)

二、        反编译前准备

A.        新建一个与要反编译程序相同名称的项目.

B.        新建一个与要反编译程序相同名称的窗体,删除窗体自带控件如MainMenu控件,删除*.Designer.cs文件.

三、        反编译

A.        将”EXE”或”DLL”文件拖入”Reflector”.得到如下界面.

B.        将代码拷贝到你刚建立的文件中去,例如得到如下代码:

using System;

using System.Linq;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

 

namespace Test

{

    public class Form1 : Form

    {

        // Fields

        private Button button1;

        private IContainer components = null;

        private Label label1;

        private ListBox listBox1;

 

        // Methods

        public Form1()

        {

            this.InitializeComponent();

        }

 

        private void button1_Click(object sender, EventArgs e)

        {

            MessageBox.Show("HelloWorld");

        }

 

        protected override void Dispose(bool disposing)

        {

            if (disposing && (this.components != null))

            {

                this.components.Dispose();

            }

            base.Dispose(disposing);

        }

 

        private void InitializeComponent()

        {

            this.button1 = new Button();

            this.label1 = new Label();

            this.listBox1 = new ListBox();

            base.SuspendLayout();

            this.button1.Location = new Point(0x54, 0xe8);

            this.button1.Name = "button1";

            this.button1.Size = new Size(0x48, 20);

            this.button1.TabIndex = 0;

            this.button1.Text = "button1";

            this.button1.Click += new EventHandler(this.button1_Click);

            this.label1.Location = new Point(4, 12);

            this.label1.Name = "label1";

            this.label1.Size = new Size(0xe9, 20);

            this.label1.Text = "列表:";

            this.listBox1.Items.Add("杭州");

            this.listBox1.Items.Add("厦门");

            this.listBox1.Location = new Point(4, 0x24);

            this.listBox1.Name = "listBox1";

            this.listBox1.Size = new Size(0xe9, 0xb8);

            this.listBox1.TabIndex = 2;

            base.AutoScaleDimensions = new SizeF(96f, 96f);

            base.AutoScaleMode = AutoScaleMode.Dpi;

            this.AutoScroll = true;

            base.ClientSize = new Size(240, 0x126);

            base.Controls.Add(this.listBox1);

            base.Controls.Add(this.label1);

            base.Controls.Add(this.button1);

            base.Name = "Form1";

            this.Text = "DecompileExample";

            base.ResumeLayout(false);

        }

    }

}

修改的结果:

using System;

using System.Linq;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

 

namespace Test

{

    public class Form1 : Form

    {

        // Fields

        private System.Windows.Forms.Button button1;

        private IContainer components = null;

        private System.Windows.Forms.Label label1;

        private System.Windows.Forms.ListBox listBox1;

 

        // Methods

        public Form1()

        {

            this.InitializeComponent();

        }

 

        private void button1_Click(object sender, EventArgs e)

        {

            MessageBox.Show("HelloWorld");

        }

 

        protected override void Dispose(bool disposing)

        {

            if (disposing && (this.components != null))

            {

                this.components.Dispose();

            }

            base.Dispose(disposing);

        }

 

        private void InitializeComponent()

        {

            this.button1 = new System.Windows.Forms.Button();

            this.label1 = new System.Windows.Forms.Label();

            this.listBox1 = new System.Windows.Forms.ListBox();

            base.SuspendLayout();

            this.button1.Location = new System.Drawing.Point(0x54, 0xe8);

            this.button1.Name = "button1";

            this.button1.Size = new System.Drawing.Size(0x48, 20);

            this.button1.TabIndex = 0;

            this.button1.Text = "button1";

            this.button1.Click += new EventHandler(this.button1_Click);

            this.label1.Location = new System.Drawing.Point(4, 12);

            this.label1.Name = "label1";

            this.label1.Size = new System.Drawing.Size(0xe9, 20);

            this.label1.Text = "列表:";

            this.listBox1.Items.Add("杭州");

            this.listBox1.Items.Add("厦门");

            this.listBox1.Location = new System.Drawing.Point(4, 0x24);

            this.listBox1.Name = "listBox1";

            this.listBox1.Size = new System.Drawing.Size(0xe9, 0xb8);

            this.listBox1.TabIndex = 2;

            base.AutoScaleDimensions = new System.Drawing.SizeF(96f, 96f);

            base.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;

            this.AutoScroll = true;

            base.ClientSize = new System.Drawing.Size(240, 0x126);

            base.Controls.Add(this.listBox1);

            base.Controls.Add(this.label1);

            base.Controls.Add(this.button1);

            base.Name = "Form1";

            this.Text = "DecompileExample";

            base.ResumeLayout(false);

        }

    }

}

如果该窗体带有资源文件(resources),可以用Reflector工具将资源文件导出.

例如上面红色框内的资源文件就是对应上面”Form1”窗体的资源文件.

选中”DecompileExample.Form1.resources”,然后点击右键选择”Save As…”导出资源文件.

在开始菜单中找到”Visual Studio 2008 Command Prompt”命令.打开命令窗口:

将resources文件转换成resx文件.将”Form1.resx”文件拷贝到项目中覆盖原来文件.

注意:如果一个窗体带有resources文件,并且有内容的时候,在反编译的时候会如下的语句:

ComponentResourceManager manager = new

ComponentResourceManager(typeof(ClassName));
需要将上面的语句替换为
System.ComponentModel.ComponentResourceManager resources = new

System.ComponentModel.ComponentResourceManager(typeof(ClassName));这样窗体设计器才能正常识别,名字也要改为”resources”.

在查看窗体时如出现如下错误,可以重启一下Visual Studio 2008即可.

重启之后便可以正常显示了.

处理单独资源文件,我们在Reflector程序中看到红色框其实就是一个资源文件,文件名为”Resources”.

所以在项目中新建一个Resources.resx文件.根据上面的步骤将resources文件转换成resx文件,用VS2008打开界面如下:

可以选择这两条记录后拷贝粘贴到刚才新建的资源文件中即可.

四、        总结

根据上面的操作已经完成反编译的全部工作,如果在代码中用到第三方dll文件需要将dll应用到项目中来.在实际反编译工作中可能并不是那么简单,本文主要也是抛砖引玉的作用.具体情况要具体分析.
