推荐答案

如果你不能找到/引用的 ManagementObjectSearcher类可能是因为你没有正确的引用添加到：的 System.Management.dll 您的C＃项目。当然，它是由.NET 4中也支持。

if you cannot find/reference the ManagementObjectSearcher Class probably is because you did not add the proper reference to: System.Management.dll to your C# project. Surely it is supported also by .NET 4.

，你可以在这个问题看：<一href=\"http://stackoverflow.com/questions/3264888/managementobjectsearcher-select-network-printers\">ManagementObjectSearcher选择网络打印机你可以找到这样所有网络打印机：

as you can see in this question: ManagementObjectSearcher select network printers? you can find all network printers in this way:

var searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_Printer");
var results = searcher.Get();

IList<ManagementBaseObject> printers = new List<ManagementBaseObject>();

foreach (var printer in results) {
    if ((bool)printer["Network"]) {
        printers.Add(printer);
    }
}
