c# - 如何在没有管理员权限的情况下读写注册表_C#

Question

我需要在没有管理员模式的情况下在注册表中写入和读取 key 。首先我想知道这是否可行？

请找到下面的代码(它工作正常，当 Visual Studio 在管理员模式下打开时)

写

RegistryKey key = Registry.LocalMachine.OpenSubKey("Software", true);

key.CreateSubKey("AppName");
key = key.OpenSubKey("AppName", true);

key.CreateSubKey("AppVersion");
key = key.OpenSubKey("AppVersion", true);

key.SetValue("myval", "677");
key.Close();

阅读

RegistryKey key = Registry.LocalMachine.OpenSubKey("Software", true);

  key.CreateSubKey("AppName");
  key = key.OpenSubKey("AppName", true);
   //if it does exist, retrieve the stored values  
  if (key != null)
  {
    string s = (string)key.GetValue("myval");
    Console.Read();
    key.Close();
   }  

请任何人提出一种方法来做到这一点。 (我也尝试添加下面的行)

错误:

ClickOnce does not support the request execution level 'requireAdministrator'.

这里有一个答案 how to write in registry without admin

读取是通过使用 RegistryKeyPermissionCheck.ReadSubTree 选项完成的

    RegistryKey baseRegistryKey = RegistryKey.OpenBaseKey(baseKey, RegistryView.Registry64);
    RegistryKey subRegistryKey = baseRegistryKey.OpenSubKey(subKey, RegistryKeyPermissionCheck.ReadSubTree);
    if (subRegistryKey != null)
    {
        object value64 = subRegistryKey.GetValue(value);
        if (value64 != null)
        {
            baseRegistryKey.Close();
            subRegistryKey.Close();
            return value64;
        }
        subRegistryKey.Close();
    }            
    baseRegistryKey.Close();

然后对 RegistryView.Registry32 做同样的事情
