Question

我想从Windows帐户中删除打印机。这将通过Citrix使用。首先，我想检索为用户安装的所有打印机，然后我想删除打印机。

我使用以下代码执行此操作。这适用于普通PC。但是，当我通过Citrix使用它时，它不起作用。并非所有打印机都通过此方法检索。我也无法删除打印机。有人知道为什么吗？如何通过Citrix使用此功能？通过Citrix使用它有什么不同？

using System.Collections.Generic;
using System.Linq;
using System.Management;

namespace RemovePrinter
{
    public class PrinterManager
    {
        public List<string> GetInstalledPrinters()
        {
            var managementScope = new ManagementScope(ManagementPath.DefaultPath);
            managementScope.Connect();

            var selectQuery = new SelectQuery {QueryString = @"SELECT * FROM Win32_Printer"};

            var objectSearcher = new ManagementObjectSearcher(managementScope, selectQuery);
            var ojectCollection = objectSearcher.Get();

            return (from ManagementBaseObject item in ojectCollection select item["Name"].ToString()).ToList();
        }

        public bool DeletePrinter(string printerName)
       {
           var managementScope = new ManagementScope(ManagementPath.DefaultPath);
           managementScope.Connect();

           var selectQuery = new SelectQuery
           {
               QueryString = @"SELECT * FROM Win32_Printer WHERE Name = '" +
                          printerName.Replace("\\", "\\\\") + "'"
           };

           var ojectSearcher = new ManagementObjectSearcher(managementScope, selectQuery);
           var ojectCollection = ojectSearcher.Get();

           if (ojectCollection.Count == 0) return false;

           foreach (var item in ojectCollection.Cast<ManagementObject>())
           {
               item.Delete();
               return true;
           }

           return false;
       }
   }
}

ManagementObjectSearcher是WMI API类的一部分。默认情况下，Citrix上未启用这些服务，这就是它无法正常工作的原因。您需要安装正确的服务，并且拥有使用这些服务的许可。看看“http://support.citrix.com/article/ctx116423”
