ManagementObjectSearcher 不包含 Get 的定义

Question

I'm trying to get this simple piece of code to work.

    public void GetHDDSerial()
    {
        var hdd = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive WHERE Index = '0'")
            .Get()
            .Cast<ManagementObject>()
            .First();
        MessageBox.Show(hdd["Model"].ToString());
    }

using System.Management is present, and I've also made a reference to the assembly (Visual Studio > Project > Add Reference > System.Management).

The error I'm getting is that the Get() method is not defined. Specifically:

Error CS1061 'ManagementObjectSearcher' does not contain a definition for 'Get' and no extension method 'Get' accepting a first argument of type 'ManagementObjectSearcher' could be found (are you missing a using directive or an assembly reference?)

How come? I thought that the getters and setters were predefined. Do I need to reference anything else?

EDIT : Going through the ManagementObjectSearcher, and listing all the methods that are actually there, I get these methods: ToString , Equals , GetHashCode , GetType .

EDIT #2 : Going to the definition (F12, or right-clicking), I get this:

namespace myProgram
{
    internal class ManagementObjectSearcher
    {
        private string v;

        public ManagementObjectSearcher(string v)
        {
            this.v = v;
        }
    }
}

.NET version is 4.6.01055, and I'm using Visual Studio 2015 Enterprise.

Answer 1

Figured out what the issue was. I must've clicked and accepted one of the suggested fixes without realizing, which created an override. Apologies for wasting everyone's time.

Answer 2

This code works for me and properly lists my primary drive. I added the following usings and added references to System.Management and System.Management.Instrumentation. Should be working for you to with .NET 4.6.1.

using System;
using System.Linq;
using System.Management;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            var hdd = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive WHERE Index = '0'")
            .Get()
            .Cast<ManagementObject>()
            .First();
            Console.WriteLine(hdd["Model"].ToString());

            Console.Read();

        }
    }
}

sample output: "Samsung SSD 840 EVO 250GB"

使用 .NET 4.7.2 构建 .NET 库时遇到同样的问题 通过 nuget https://www.nuget.org/packages/System.Management/安装 System.Management 包解决了该问题
