访问Win32_OperatingSystem的属性

本文关键字：属性 OperatingSystem Win32 访问 | 更新日期: 2023-09-27 18:03:56

我试图使用Win32_OperatingSystem属性中存储的值来填充windows窗体中的几个文本框。我用的是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() });
         }

下面是我得到的例外- 

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

你能告诉我什么是例外，我该如何克服它吗?

访问Win32_OperatingSystem的属性

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);
            }
        }
    }
}

你不使用属性在foreach 循环中获取值。请记住属性。值可以为空。属性。值是一个对象，可以是String或Array。这是我编写的一段代码的摘录，可以帮助你:

mo  //ManagementObject
    .Properties
    .OfType<PropertyData>()
    .ToList()
    .ForEach(p =>
    {
        String str = String.Empty;
        if (p.Value != null)
             if (p.Value.GetType().BaseType == typeof(Array)) // Value is a array, special string creation
             {
                 Array list = (p.Value as Array);
                 foreach (object o in list)
                      str += o.ToString() + "-";
                 if (list.Length > 0)
                      str = str.Substring(0, str.Length - 1);
             }
             else // value is already a string
                 str = p.Value.ToString();
         this.ListDuet
             .Add(new Duet()
             {
                 Key = Convert.ToString(p.Name),
                 Value = str
             });
     });

Duet是我用来方便地管理我的数据的类。
