開始工做編輯器

1.簡單編寫一個產生隨機數的Winform窗口程序ide

 

 

 代碼以下工具

using System;
using System.Windows.Forms;

namespace ConfuserEx_Test
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            var max = (double)numericUpDown1.Value;
            var min = (double)numericUpDown2.Value;
            Random random = new Random();
            double v = random.NextDouble() * (max -min) + min;
            label1.Text = v.ToString();
            textBox1.AppendText(v.ToString() + "\r\n");

        }
    }
}
Form1.cs
namespace ConfuserEx_Test
{
    partial class Form1
    {
        /// <summary>

其功能如圖:測試

 

 

 2.下載打開ConfuserEx使用this

2.1 將生成的exe文件拖拽到ConfuserEx的Project中加密

 

 

 2.2在Settings中選中Packer(聽說dll文件不是這樣的),再點擊exe文件,添加一個True。spa

 

 

 2.3點擊Protect!看到Finished at xx:xx, xx:xx elapsed.表示完成

 

 

 3.測試加密混淆結果

3.1下載ILSpy--(百度百科:ILspy是一個開源的.net反編譯軟件,使用十分方便。)

3.2將保護前編譯出的exe文件拖拉到ILSpy中

很方便就可以看到源碼

 

3.2 將保護後的exe文件拖拉到ILSpy中與以前的作對比

 

 

4.結論

簡單的測試了一下,這種保護便於操做,有明顯的保護效果,可以防止只會下載反編譯軟件來得到源碼的人,可是可能不是全部反編譯軟件都能防止。只是作個簡單保護。

後面我會作一個Reflector反編譯實驗以及脫殼後再來反編譯。

附加1

Reflector反編譯實驗結果,保護後的直接打不開
