介绍

dnSpy是一款针对.NET程序的逆向工程工具 , 可以使用它反编译.NET代码。

效果

为了测试简单写了一个窗体程序，代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace test_winform
{
    public partial class Form1 : Form
    {
        int a = 1;
        string b = "asd";
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("123");

        }
    }
}

打开 dnSpy ，将程序拖入，反编译完成后如下：

关键代码的反编译效果：

using System;
using System.ComponentModel;
using System.Drawing;
using System.Windows.Forms;

namespace test_winform
{
	// Token: 0x02000002 RID: 2
	public class Form1 : Form
	{
		// Token: 0x06000001 RID: 1 RVA: 0x00002050 File Offset: 0x00000250
		public Form1()
		{
			this.InitializeComponent();
		}

		// Token: 0x06000002 RID: 2 RVA: 0x0000207A File Offset: 0x0000027A
		private void button1_Click(object sender, EventArgs e)
		{
			MessageBox.Show("123");
		}

		// Token: 0x06000003 RID: 3 RVA: 0x00002088 File Offset: 0x00000288
		protected override void Dispose(bool disposing)
		{
			bool flag = disposing && this.components != null;
			if (flag)
			{
				this.components.Dispose();
			}
			base.Dispose(disposing);
		}

		// Token: 0x06000004 RID: 4 RVA: 0x000020C0 File Offset: 0x000002C0
		private void InitializeComponent()
		{
			this.button1 = new Button();
			base.SuspendLayout();
			this.button1.Location = new Point(394, 156);
			this.button1.Name = "button1";
			this.button1.Size = new Size(75, 23);
			this.button1.TabIndex = 0;
			this.button1.Text = "button1";
			this.button1.UseVisualStyleBackColor = true;
			this.button1.Click += this.button1_Click;
			base.AutoScaleDimensions = new SizeF(6f, 12f);
			base.AutoScaleMode = AutoScaleMode.Font;
			base.ClientSize = new Size(800, 450);
			base.Controls.Add(this.button1);
			base.Name = "Form1";
			this.Text = "Form1";
			base.ResumeLayout(false);
		}

		// Token: 0x04000001 RID: 1
		private int a = 1;

		// Token: 0x04000002 RID: 2
		private string b = "asd";

		// Token: 0x04000003 RID: 3
		private IContainer components = null;

		// Token: 0x04000004 RID: 4
		private Button button1;
	}
