问题描述

大家好



我是c＃

注册表编程的新手我有代码，这没有任何错误，但它是不工作！



我想在Windows 8.1 Pro上禁用Hibernate N



这里有什么问题？< br $> b $ b

  private   void  button1_Click（ object  sender，EventArgs e）
 {
 尝试 
 {
 RegistryKey mykey = Registry.LocalMachine.OpenSubKey（  SYSTEM \\CurrentControlSet \\Control \\Power， true ）; 
 mykey.SetValue（  HibernateEnabled， 0 ）; 
 mykey.Close（）; 
 
} 
  catch  {} 
} 

非常感谢:)（div class = h2_lin>解决方案

您可能需要管理员权限才能更改注册表的SYSTEM区域，因此您的修改将被拒绝。



这是一个很好的例子，为什么吞咽异常是一个坏主意：你不知道有问题或任何细节，只是代码不起作用。



更改你的收益：

  catch （例外情况）
 {
 Debug.WriteLine（ex.Message）; 
} 

它会告诉你问题是什么。



几乎可以肯定，这是一个授权问题。这可能是一种更好的方法： https://social.msdn.microsoft.com/Forums/vstudio/en-US/386e0268-8986-4e49-8023-f9ae2e2689ab/disabling-hibernation?forum=csharpgeneral [ ^ ]

hi everybody

I'm new to registry programming with c#
I have a code, this has not any error but it's not working!

I want to disable Hibernate on windows 8.1 Pro N

what's wrong here?

private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                RegistryKey mykey = Registry.LocalMachine.OpenSubKey("SYSTEM\\CurrentControlSet\\Control\\Power", true);
                mykey.SetValue("HibernateEnabled", 0);
                mykey.Close();

            }
            catch { }
        }

thanks a lot :)

解决方案

The chances are that you need admin permission to change the SYSTEM area of the registry and your modification is being rejected as a result.

This is a good example of why swallowing exceptions is a bad idea: you have no idea there is a problem, or any details about it, just that the code doesn't work.

Change your catch:

catch (Exception ex)
   {
   Debug.WriteLine(ex.Message);
   }

And it will tell you what the problem is.

Almost certainly, it's an authorization problem. This may be a better way to do it: https://social.msdn.microsoft.com/Forums/vstudio/en-US/386e0268-8986-4e49-8023-f9ae2e2689ab/disabling-hibernation?forum=csharpgeneral[^]
