我没有得到我应该导入我的C＃.NET应用程序中使用的Win32类哪个命名空间？

I am not getting which namespace I should import to use Win32 classes in My c#.net application?

推荐答案

为了获得从C＃（或.NET）访问WMI必须导入的 System.Management 命名空间。此外，如果您是初次使用WMI尝试像 WMI Delphi代码造物主 它可以帮助你创建一个C＃代码段访问WMI。

In order to get access to the WMI from C# (or .Net) you must import the System.Management namespace. Also if you are new using the WMI try a tool like the WMI Delphi Code Creator which can help you to create a C# snippet to access the WMI.

试试这个示例代码，通过该工具创建

Try this sample code, created by the tool.

using System;
using System.Collections.Generic;
using System.Management;
using System.Text;

namespace GetWMI_Info
{
    class Program
    {

        static void Main(string[] args)
        {
            try
            {
                string ComputerName = "localhost";
                ManagementScope Scope;                

                if (!ComputerName.Equals("localhost", StringComparison.OrdinalIgnoreCase)) 
                {
                    ConnectionOptions Conn = new ConnectionOptions();
                    Conn.Username  = "";
                    Conn.Password  = "";
                    Conn.Authority = "ntlmdomain:DOMAIN";
                    Scope = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", ComputerName), Conn);
                }
                else
                    Scope = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", ComputerName), null);

                Scope.Connect();
                ObjectQuery Query = new ObjectQuery("SELECT * FROM Win32_PrintJob");
                ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, Query);

                foreach (ManagementObject WmiObject in Searcher.Get())
                {
                    Console.WriteLine("{0,-35} {1,-40}","Document",WmiObject["Document"]);// String
                    Console.WriteLine("{0,-35} {1,-40}","Name",WmiObject["Name"]);// String

                }
            }
            catch (Exception e)
            {
                Console.WriteLine(String.Format("Exception {0} Trace {1}",e.Message,e.StackTrace));
            }
            Console.WriteLine("Press Enter to exit");
            Console.Read();
        }
    }
}
