C#实现Windows开机自启动

Windows开机自启动的API原理是向注册表

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

对应应用程序的运行路径，或者说启动命令，允许带参数。

HKEY_CURRENT_USER与HKEY_LOCAL_MACHINE

注册表HKEY_CURRENT_USER节点下的内容仅针对当前登录的用户生效，Windows是多账户系统（不是多用户系统，多用户允许同时多个用户登录使用当前计算机系统），不同账户下有不同的配置。

注册表HKEY_LOCAL_MACHINE节点下的内容都是针对系统所有用户生效的。

C#可以直接调用Windows API接口读写注册表

第一、实现写注册表的函数

private static bool WriteRegistryValue(RegistryKey regKey, String keyName, String value)
{if (null == keyName || 0 == keyName.Trim().Length){Console.WriteLine("WriteRegistryValue, invalid keyName: " + keyName);return false;}if (null == value || 0 == value.Trim().Length){Console.WriteLine("WriteRegistryValue, invalid value: " + value);return false;}try{bool needChange = false;String[] names = regKey.GetValueNames();if (null != names){for (int i = 0; i < names.Length; i++){String oldValue = (String)regKey.GetValue(keyName, "");if (null == oldValue || !oldValue.Equals(value)){needChange = true;break;}}}if (needChange){regKey.SetValue(keyName, value);}return true;}catch (SecurityException e){Console.WriteLine("WriteRegistryValue, SecurityException ");}catch (ObjectDisposedException e){Console.WriteLine("WriteRegistryValue, ObjectDisposedException");}catch (System.IO.IOException e){Console.WriteLine("WriteRegistryValue, IOException");}catch (UnauthorizedAccessException e){Console.WriteLine("WriteRegistryValue, IOException");}return false;
}

第二、实现向注册表节点Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run写入数值的函数

public static String getAutoStartKeyName(String softwareName, String softwarePath)
{if (null == softwareName || 0 == softwareName.Trim().Length){return "";}if (null == softwarePath || 0 == softwarePath.Trim().Length){return "";}String md5sum = Md5sum(softwarePath);return softwareName + "_" + md5sum.Substring(0, 8);
}public static bool setAutoStart(String softwareName, String softwarePath)
{if (null == softwareName || 0 == softwareName.Trim().Length){Console.WriteLine("invalid softwareName: " + softwareName);return false;}if (null == softwarePath || 0 == softwarePath.Trim().Length){Console.WriteLine("invalid softwarePath: " + softwarePath);return false;}RegistryKey localMachineKey = RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64);RegistryKey regKeyRun = localMachineKey.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run", true);RegistryKey regKeySoftware = null, regKeyMiscrosoft = null, regKeyWindows = null, regKeyCurrentVersion = null;try{if (null == regKeyRun){Console.WriteLine("openSubKey failed. try create it.");regKeySoftware = localMachineKey.CreateSubKey("Software");regKeyMiscrosoft = regKeySoftware.CreateSubKey("Microsoft");regKeyWindows = regKeyMiscrosoft.CreateSubKey("Windows");regKeyCurrentVersion = regKeyWindows.CreateSubKey("CurrentVersion");regKeyRun = regKeyCurrentVersion.CreateSubKey("Run");}String keyName = getAutoStartKeyName(softwareName, softwarePath);return WriteRegistryValue(regKeyRun, keyName, softwarePath);}finally{SafeCloseRegKey(regKeyRun); regKeyRun = null;SafeCloseRegKey(regKeyCurrentVersion); regKeyCurrentVersion = null;SafeCloseRegKey(regKeyWindows); regKeyWindows = null;SafeCloseRegKey(regKeyMiscrosoft); regKeyMiscrosoft = null;SafeCloseRegKey(regKeySoftware); regKeySoftware = null;}
}private static void SafeCloseRegKey(RegistryKey regKey)
{if (null != regKey){regKey.Close();}
}public static String Md5sum(String input)
{// step 1, calculate MD5 hash from inputSystem.Security.Cryptography.MD5 md5 = System.Security.Cryptography.MD5.Create();byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(input);byte[] hash = md5.ComputeHash(inputBytes);// step 2, convert byte array to hex stringStringBuilder sb = new StringBuilder();for (int i = 0; i < hash.Length; i++){sb.Append(hash[i].ToString("X2"));}return sb.ToString();
}

大家注意到String getAutoStartKeyName(String softwareName, String softwarePath)函数，这里是为了防止注册表中的name存在相同的情况造成冲突，因此将程序路劲也放进去MD5计算生成唯一的name保证不会冲突。

第三、实现关闭自启动

其实就是将自启动信息从注册表中删除

public static bool RemoveAutoStart(String softwarePath)
{if (null == softwarePath || 0 == softwarePath.Trim().Length){return false;}RegistryKey localMachineKey = RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64);RegistryKey regKeyRun = localMachineKey.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run", true);if (null == regKeyRun){return false;}try{String[] names = regKeyRun.GetValueNames();if (null == names || 0 == names.Length){return false;}String value;foreach (String name in names){value = (String)regKeyRun.GetValue(name, "");if (softwarePath.Equals(value)){regKeyRun.DeleteValue(name);return true;}}}catch (SecurityException e){Console.WriteLine("SecurityException");}catch (ObjectDisposedException e){Console.WriteLine("ObjectDisposedException");}catch (System.IO.IOException e){Console.WriteLine("IOException");}catch (UnauthorizedAccessException e){Console.WriteLine("IOException");}finally{SafeCloseRegKey(regKeyRun); regKeyRun = null;}return false; // TODO
}

第四、实现判断当前路径是否有自启动的方法

因为在本人工具中只设置当前用户的自启动，所以判断时只判断当前用户，如果需要所有用户请使用HKEY_LOCAL_MACHINE对应的参数

public static bool IsAutoStart(String softwarePath)
{if (null == softwarePath || 0 == softwarePath.Trim().Length){return false;}RegistryKey localMachineKey = RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64);RegistryKey regKeyRun = localMachineKey.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run", true);if (null == regKeyRun){return false;}try{String[] names = regKeyRun.GetValueNames();if (null == names || 0 == names.Length){return false;}String value;foreach (String name in names){value = (String)regKeyRun.GetValue(name, "");if (softwarePath.Equals(value)){return true;}}}catch (SecurityException e){Console.WriteLine("SecurityException");}catch (ObjectDisposedException e){Console.WriteLine("ObjectDisposedException");}catch (System.IO.IOException e){Console.WriteLine("IOException");}catch (UnauthorizedAccessException e){Console.WriteLine("IOException");}finally{SafeCloseRegKey(regKeyRun); regKeyRun = null;}return false;
}

因为小工具是自己使用的，所以没有考虑到全局用户，全局用户需要administrator权限，大家用VS编译时增加对应权限就可以了。
