c# - 访问 Win32_OperatingSystem 的属性

Question

我正在尝试使用存储在 Win32_OperatingSystem 属性中的值在 Windows 窗体中填充一些文本框。我使用的是 Windows 7。

下面是我使用的代码

 ArrayList prName = new ArrayList();
        ArrayList prValue = new ArrayList();
        int i = 0;
        ManagementClass msClassOS = new ManagementClass("Win32_OperatingSystem");
        msClassOS.Options.UseAmendedQualifiers = true;
        PropertyDataCollection properties = msClassOS.Properties;
        foreach (PropertyData property in properties)
        {
            prName.Add(property.Name);
        }

        foreach (PropertyData property in properties)
        {
            prValue.Add(new string[] { msClassOS.GetPropertyValue("Value").ToString() });
         }

以下是我得到的异常 -

System.Management.ManagementException: Not found 
at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
at System.Management.PropertyData.RefreshPropertyInfo()
at System.Management.PropertyDataCollection.get_Item(String propertyName)
at System.Management.ManagementBaseObject.GetPropertyValue(String propertyName)
at NetworkMonitoringSoftware.Form1.tabControl1_Selected(Object sender, TabControlEventArgs e) in C:\Users\OWNER\Documents\Visual Studio 2010\Projects\NetworkMonitoringSoftware\NetworkMonitoringSoftware\Form1.cs:line 

你能告诉我异常是什么以及我如何克服它吗？

提前致谢。

你可以试试下面的代码:

using System;
using System.Management;
namespace WMISample
{
    public class MyWMIQuery
    {
        public static void Main()
        {             
            try
            {
                ManagementClass osClass = new ManagementClass("Win32_OperatingSystem");
                foreach (ManagementObject queryObj in osClass.GetInstances())
                {
                    foreach (PropertyData prop in queryObj.Properties)
                    {
                        //add these to your arraylist or dictionary 
                      Console.WriteLine("{0}: {1}", prop.Name, prop.Value);
                    }                    
                }
            }
            catch (ManagementException e)
            {
                //MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
            }
        }
    }
}
