破解 一个程序 反编译出来的关键代码 ，但看不懂代码 中flag这个是怎样判断 的，求解答下，先谢了。原贴是这里http://www.52pojie.cn/thread-234462-4-1.html 。 iLspy_Master_2.0.0反编译器 // Schematic_Symbol_Wizard.frmSplashScreen public void funGetMacAddress() {         NetworkInterface[] allNetworkInterfaces = NetworkInterface.GetAllNetworkInterfaces();         int num = 0;         string text = null;         NetworkInterface[] array = allNetworkInterfaces;         checked         {                 bool flag;                 for (int i = 0; i < array.Length; i++)                 {                         NetworkInterface networkInterface = array;                         num++;                         flag = (num == 1);                         if (flag)                         {                                 text = networkInterface.GetPhysicalAddress().ToString();                         }                 }                 this.txtUser.Text = "SN# " + Strings.Replace(Strings.Format(DateAndTime.Now, "Ryy-MMEdd"), "0", "Z", 1, -1, CompareMethod.Binary) + " is licensed to:\r\n";                 this.txtUser.Text = this.txtUser.Text + "Computer Name: " + MyProject.Computer.Name + "\r\n";                 this.txtUser.Text = this.txtUser.Text + "User Name: " + this.GetUserName() + "\r\n";                 this.txtUser.Text = this.txtUser.Text + "Host ID:" + text + "\r\n";                 string[] array2 = new string[Strings.Len(text) + 1];                 int arg_128_0 = 0;                 int num2 = Strings.Len(text);                 int num3 = arg_128_0;                 while (true)                 {                         int arg_145_0 = num3;                         int num4 = num2;                         if (arg_145_0 > num4)                         {                                 break;                         }                         array2[num3] = Strings.Mid(text, num3 + 1, 1);                         num3++;                 }                 flag = (Operators.CompareString(this.arrLicenseCode[0], array2[8], false) == 0 & Operators.CompareString(this.arrLicenseCode[1], this.MACtoSecret(array2[0]), false) == 0 & Operators.CompareString(this.arrLicenseCode[2], this.MACtoSecret(array2[1]), false) == 0 & Operators.CompareString(this.arrLicenseCode[3], "-", false) == 0 & Operators.CompareString(this.arrLicenseCode[4], this.MACtoSecret(array2[2]), false) == 0 & Operators.CompareString(this.arrLicenseCode[5], array2[9], false) == 0 & Operators.CompareString(this.arrLicenseCode[6], "-", false) == 0 & Operators.CompareString(this.arrLicenseCode[7], this.MACtoSecret(array2[3]), false) == 0 & Operators.CompareString(this.arrLicenseCode[8], this.MACtoSecret(array2[4]), false) == 0 & Operators.CompareString(this.arrLicenseCode[9], array2[10], false) == 0 & Operators.CompareString(this.arrLicenseCode[10], this.MACtoSecret(array2[5]), false) == 0 & Operators.CompareString(this.arrLicenseCode[11], "-", false) == 0 & Operators.CompareString(this.arrLicenseCode[12], this.MACtoSecret(array2[6]), false) == 0 & Operators.CompareString(this.arrLicenseCode[13], array2[11], false) == 0 & Operators.CompareString(this.arrLicenseCode[14], this.MACtoSecret(array2[7]), false) == 0);                 if (flag)                 {                         this.lblStatus1.ForeColor = Color.DarkGreen;                         this.lblStatus1.Text = "Status: Registered";                         MyProject.Forms.frmSchematicSymbolWizard.lblStatus.BackColor = Color.Green;                 }                 else                 {                         this.lblStatus1.ForeColor = Color.DarkRed;                         this.lblStatus1.Text = "Status: Unregistered";                         MyProject.Forms.frmSchematicSymbolWizard.lblStatus.BackColor = Color.Red;                         this.EvalPeriod();                         Interaction.MsgBox("Product ID not found, running in demo mode.\r", MsgBoxStyle.Critical, "Software registration");                 }         } }

前两句摘取MSDN，其他注释自己分析哈。新手见谅！

[C#] 纯文本查看 复制代码

 NetworkInterface[] allNetworkInterfaces = NetworkInterface.GetAllNetworkInterfaces();//返回描述本地计算机上的网络接口的对象。//包含描述可用网络接口的对象的 NetworkInterface 数组，如果没有检测到接口，则为空数组。
            int num = 0;
            string text = null;
            NetworkInterface[] array = allNetworkInterfaces;
            checked//开始检测
            {
                bool flag;
                for (int i = 0; i < array.Length; i++)
                {
                    NetworkInterface networkInterface = array;//可能是多个对象或者一个也没有
                    num++;
                    flag = (num == 1);//如果num等于1真，反之为假
                    if (flag)
                    {
                        text = networkInterface.GetPhysicalAddress().ToString();//获取MAC物理地址。
                    }
                }
            }

简单说flag用来获取MAC地址的。
