c# 写注册表的神奇问题

Question

string fileFullName = @System.Windows.Forms.Application.ExecutablePath;
            string fileName = fileFullName.Substring(fileFullName.LastIndexOf("\\") + 1);
                     const string strSubKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Run\";            RegistryKey rKey = Registry.LocalMachine.OpenSubKey(strSubKey,true);
                          if (rKey != null)
                {
                    //MessageBox.Show(rKey.Name);
                    rKey.SetValue(fileName, fileFullName);//Run下面冒出一个新项 #1
                    rKey.Close();
                    this.Menu_config_autoRun.Checked = true;
                }
          执行该方法后，在Run项下面冒出个子项：新项 #1
不只是怎么回事

Answer 1

const string strSubKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Run\";改成 const string strSubKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Run";
