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;  
                  }
