如何在asp.net中的web应用程序中使用管理类

问题描述

我正在尝试编写一个会破坏打印机状态的代码

使用System.Management; 

 ManagementScope scope = new ManagementScope（\\ root\\cimv2\" ）; 
 
 scope.Connect（）; 
 
 //从WMI对象集合中选择打印机
 
 ManagementObjectSearcher searcher = new ManagementObjectSearcher（SELECT * FROM Win32_Printer）; 
 
 string printerName =; 
 
 foreach（searcher.Get（）中的ManagementObject打印机）{
 
 printerName = printer（Name）。ToString（）。ToLower（）; 
 
 if（printerName.Equals（Name_Of_Printer））
 
 {
 
 Console.WriteLine（Printer =+ printer（Name） ））; 
 
 if（printer（WorkOffline）。ToString（）。ToLower（）。Equals（true））
 
 {
 
 / / printer由用户离线
 
 Console.WriteLine（您的Plug-N-Play打印机未连接。）; 
 
} 
 
 else 
 
 {
 
 //打印机不离线
 
控制台.WriteLine（你的Plug-N-Play打印机已连接。）; 
 
} 
} 

但我收到的错误为

 错误  54 类型或 命名空间 name ' 找不到ManagementScope（你错过了吗？使用指令或程序集引用？）C：\ Users \d3 \Desktop \ Nuggetts Cloud \Project\asset_cardmstr.aspx.cs 54 6 C：\ ... \ Project \  

请帮助现在缺少的东西。？

解决方案

Hi,

I am trying to write a code which will defect printer status

using System.Management;

 ManagementScope scope = new ManagementScope("\\root\\cimv2");

       scope.Connect();

// Select Printers from WMI Object Collections

       ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Printer");

string printerName = "";

foreach (ManagementObject printer in searcher.Get()) {

printerName = printer("Name").ToString().ToLower();

if (printerName.Equals("Name_Of_Printer"))

{

Console.WriteLine("Printer = " + printer("Name"));

if (printer("WorkOffline").ToString().ToLower().Equals("true"))

{

// printer is offline by user

Console.WriteLine("Your Plug-N-Play printer is not connected.");

}

else

{

// printer is not offline

Console.WriteLine("Your Plug-N-Play printer is connected.");

}
} 

But i am getting error as

Error   54  The type or namespace name 'ManagementScope' could not be found (are you missing a using directive or an assembly reference?)   C:\Users\d3\Desktop\Nuggetts Cloud\Project\asset_cardmstr.aspx.cs  54  6   C:\...\Project\

Please help what is missing now.??
