您的问题似乎不完整，您是想询问关于C语言编程的某个具体问题吗？比如C语言的语法、编程技巧、项目开发等。请提供更具体的信息，这样我才能给出更准确的回答。

方法一：第一步：添加引用 using System.Printing; 第二步：代码 public static List GetPrintList() { List lt=new List(); LocalPrintServer printServer=new LocalPrintServer(); PrintQueueCollection printQueues=printServer.GetPrintQueues(); }

方法一

第一步：添加引用

using System.Printing;

第二步：代码

public static List<string> GetPrintList() { List<string> lt = new List<string>(); LocalPrintServer printServer = new LocalPrintServer(); PrintQueueCollection printQueuesOnLocalServer = printServer.GetPrintQueues(new[] { EnumeratedPrintQueueTypes.Local }); foreach (PrintQueue printer in printQueuesOnLocalServer) lt.Add(printer.Name); return lt; }

方法二

需要引入

System.Drawing.Printing System.Management

实现

1.获取打印机列表
2.获取默认打印机
3.设置默认打印机

上代码

public class PrinterExample { /// <summary> /// 设置默认打印机 /// </summary> /// <param name="Name"></param> /// <returns></returns> [DllImport("winspool.drv")] public static extern bool SetDefaultPrinter(String Name); //调用win api将指定名称的打印机设置为默认打印机 /// <summary> /// 获取默认打印机 /// </summary> /// <returns></returns> public static string GetDefaultPrinter() { PrintDocument print = new PrintDocument(); string defaultName = print.PrinterSettings.PrinterName;//默认打印机名 return defaultName; } /// <summary> /// 获取本地所有打印机 /// </summary> /// <returns></returns> public static List<String> GetLocalPrinters() { List<String> printer_names = new List<String>(); foreach (String item in PrinterSettings.InstalledPrinters) { printer_names.Add(item); } return printer_names; } /// <summary> /// 获取本地所有打印机 System.Management方式获取 /// </summary> /// <returns></returns> public static List<String> GetLocalPrinters2() { List<String> printer_names = new List<String>(); ManagementObjectCollection queryCollection; string _classname = "SELECT * FROM Win32_Printer"; Dictionary<string, ManagementObject> dict = new Dictionary<string, ManagementObject>(); ManagementObjectSearcher query = new ManagementObjectSearcher(_classname); queryCollection = query.Get(); foreach (ManagementObject mo in queryCollection) { string oldName = mo["Name"].ToString(); printer_names.Add(oldName); } return printer_names; } }
