获得本机的可用的所有打印机

1.获得本机的可用的所有打印机的列表

using   System.Collections.Specialized;  
  using   System.Management;  
  使用此方法:  
                  public   static   StringCollection   GetPrintersCollection()  
                  {  
                          StringCollection   printerNameCollection   =   new   StringCollection();  
                          string   searchQuery   =   "SELECT   *   FROM   Win32_Printer";  
                          ManagementObjectSearcher   searchPrinters   =  
                                      new   ManagementObjectSearcher(searchQuery);  
                          ManagementObjectCollection   printerCollection   =   searchPrinters.Get();  
                          foreach   (ManagementObject   printer   in   printerCollection)  
                          {  
                                  printerNameCollection.Add(printer.Properties["Name"].Value.ToString());  
                          }  
                          return   printerNameCollection;  
                  }  
  获取:  
                          StringCollection   sc   =   GetPrintersCollection();  
                          for   (int   i   =   0;   i   <   sc.Count;   i++)  
                          {  
                                  //得到可用打印机名列表  
                                  MessageBox.Show(sc[i].ToString());  
                          }

 2.设为默认打印机.  

public   static   bool   SetDefaultPrinter(string   printerName)  
                  {  
                          bool   setDefaulted   =   false;  
                          ManagementObjectSearcher   query;  
                          ManagementObjectCollection   querycollection;  
                          string   _classname   =   "select   *   from   win32_printer";  
   
                          query   =   new   ManagementObjectSearcher(_classname);  
                          querycollection   =   query.Get();  
   
                          foreach   (ManagementObject   mo   in   querycollection)  
                          {  
                                  if   (string.Compare(mo["name"].ToString(),   printerName,   true)   ==   0)  
                                  {  
                                          mo.InvokeMethod("setdefaultprinter",   null);  
                                          setDefaulted   =   true;  
                                          break;  
                                  }  
                          }  
                          return   setDefaulted;  
                  }
