如何设置机箱风扇速度 [英] How Do I Set case Fan Speed

问题描述

我想创建代码，在案例粉丝上设置速度，并且必须在Windows 7上工作。我尝试使用WMI代码创建者，但我收到错误无效的对象路径

I want create code which set speed on case fan and must working on windows 7. I try use WMI code creator but i got error " Invalid object path"

using System;
using System.Management;
using System.Windows.Forms;

namespace WMISample
{
    public class CallWMIMethod
    {
        public static void Main()
        {
            try
            {
                ManagementObject classInstance = 
                    new ManagementObject("root\\CIMV2", 
                    "Win32_Fan.ReplaceKeyPropery='ReplaceKeyPropertyValue'",
                    null);

                // Obtain in-parameters for the method
                ManagementBaseObject inParams = 
                    classInstance.GetMethodParameters("SetSpeed");

                // Add the input parameters.
                inParams["DesiredSpeed"] =  600;

                // Execute the method and obtain the return values.
                ManagementBaseObject outParams = 
                    classInstance.InvokeMethod("SetSpeed", inParams, null);

                // List outParams
                Console.WriteLine("Out parameters:");
                Console.WriteLine("ReturnValue: " + outParams["ReturnValue"]);
            }
            catch(ManagementException err)
            {
                MessageBox.Show("An error occurred while trying to execute the WMI method: " + err.Message);
            }
        }
    }
}

有没有可能参考案例fan？

is there any possibility refer to case fan ?

推荐答案

并非每台机器都通过WMI提供此信息。如果您的计算机没有，您将无法访问它。仅仅因为WMI提供访问特定信息的属性并不意味着信息始终可用。

根据MSDN，Win32_Fan没有实现SetSpeed，所以你会得到

Not every machine provides this information through WMI. If your computer doesn't, you won't be able to access it. Just because WMI provides a property to access a particular piece of information doesn't mean that information will always be available.

According to MSDN, SetSpeed is not implemented for Win32_Fan, so you will get the error at

classInstance.GetMethodParameters("SetSpeed");

根据 Telnet [ ^ ]，

Win32_Fan

可以在以下平台上提供信息



Windows Server 2012否

Windows Server 2008 R2否

Windows Server 2008否

Windows Server 2003是

Windows 8否

Windows 7否

Windows Vista否

Windows XP是

Windows 2000是

can retive information on following platforms

Windows Server 2012 No
Windows Server 2008 R2 No
Windows Server 2008 No
Windows Server 2003 Yes
Windows 8 No
Windows 7 No
Windows Vista No
Windows XP Yes
Windows 2000 Yes

如果WMI没有，那么我如何访问风扇并设置速度？

if WMI no, so how i can access to fan and set speed?
