参考键入它是在“系统”定义“组件”的权利要求

Question

试图让在UWP应用一些WMI对象。在.NET 4.6运行VS2015。

我得到的错误对foreach和方法调用，指出“引用类型‘组件’声称它是在‘系统’中定义的”错误CS7069。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Management;

namespace SystemInfo
{
    class wmiObject
    {
        static osDetails Program()
        {

            ManagementObjectCollection osDetailsCollection = getWMIObject("SELECT OSType, caption FROM Win32_OperatingSystem");
            osDetails Details = new osDetails();

            foreach (ManagementObject mo in osDetailsCollection)
            {
                Details.OSName = mo["Caption"].ToString();

            }

            osDetailsCollection = getWMIObject("SELECT Description, NumberOfLogicalProcessors, L3CacheSize from Win32_Processor");

            foreach (ManagementObject mo in osDetailsCollection)
            {
                Details.NumberOfLogicalProcessors = mo["NumberOfLogicalProcessors"].ToString();
                Details.L3CacheSize = mo["L3CacheSize"].ToString();
                Details.Description = mo["Description"].ToString();

            }
            ;

            return Details;
        }

        static ManagementObjectCollection getWMIObject(string query)
        {
            ManagementObjectSearcher objOSDetails = new ManagementObjectSearcher(query);
            ManagementObjectCollection osDetailsCollection = objOSDetails.Get();
            return osDetailsCollection;

        }

        class osDetails
        {
            public string Description;
            public string OSName;
            public string NumberOfLogicalProcessors;
            public string L3CacheSize;
        }

    }


}

任何帮助，将不胜感激。

Answer 1

这可能为你工作

foreach (ManagementObject mo in osDetailsCollection)
{
    foreach (PropertyData prop in mo.Properties)
    {
        if(prop.Name == "Caption")
        Details.OSName = prop.Value;
    }
}

我只是遇到了这个问题，我找到了解决办法是改造项目作为一个C＃WindowsFormsApp。它会自动添加引用：

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.2\Microsoft.CSharp.dll
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.2\System.dll

希望这可以帮助别人了。
