C# 如何获取计算机中所有打印机的列表

我需要获取所有连接到计算机的打印机的列表

如何在C、WinForms中实现这一点？

请查看静态属性

它是系统上所有已安装打印机的名称列表

试试这个：

foreach (string printer in System.Drawing.Printing.PrinterSettings.InstalledPrinters)
{
    MessageBox.Show(printer);
}

如果您需要的信息不仅仅是打印机名称，还可以使用System.Management API查询这些信息：

var printerQuery = new ManagementObjectSearcher("SELECT * from Win32_Printer");
foreach (var printer in printerQuery.Get())
{
    var name = printer.GetPropertyValue("Name");
    var status = printer.GetPropertyValue("Status");
    var isDefault = printer.GetPropertyValue("Default");
    var isNetworkPrinter = printer.GetPropertyValue("Network");

    Console.WriteLine("{0} (Status: {1}, Default: {2}, Network: {3}", 
                name, status, isDefault, isNetworkPrinter);
}

在ASP.NET中获取网络和本地打印机列表

此方法使用Windows Management Instrumentation或WMI接口。它是一种用于获取Windows操作系统上运行的各种系统硬件信息的技术

private void GetAllPrinterList()
        {
            ManagementScope objScope = new ManagementScope(ManagementPath.DefaultPath); //For the local Access
            objScope.Connect();

            SelectQuery selectQuery = new SelectQuery();
            selectQuery.QueryString = "Select * from win32_Printer";
            ManagementObjectSearcher MOS = new ManagementObjectSearcher(objScope, selectQuery);
            ManagementObjectCollection MOC = MOS.Get();
            foreach (ManagementObject mo in MOC)
            {
                lstPrinterList.Items.Add(mo["Name"].ToString());
            }
        }

演示列出网络和本地打印机的应用程序

您还可以使用LocalPrintServer类。见：

如文档中所述：Windows服务或ASP.NET应用程序或服务中不支持System.Printing命名空间中的类。

如果您使用的是MVC，这是处理下拉列表中的打印机和串行端口的方法

using System.Collections.Generic;
using System.Linq;
using System.IO.Ports;
using System.Drawing.Printing;

    public class Miclass
    {
        private void AllViews()
        {
            List<PortClass> ports = new List<PortClass>();
            List<Printersclass> Printersfor = new List<Printersclass>();
            string[] portnames = SerialPort.GetPortNames();
            /*PORTS*/
            for (int i = 0; i < portnames.Count(); i++)
            {
                ports.Add(new PortClass() { Name = portnames[i].Trim(), Desc = portnames[i].Trim() });
            }
            /*PRINTER*/
            for (int i = 0; i < PrinterSettings.InstalledPrinters.Count; i++)
            {
                Printersfor.Add(new Printersclass() { Name = PrinterSettings.InstalledPrinters[i].Trim(), Desc = PrinterSettings.InstalledPrinters[i].Trim() });
            }
        }
    }
    public class PortClass
    {
        public string Name { get; set; }
        public string Desc { get; set; }

        public override string ToString()
        {
            return string.Format("{0} ({1})", Name, Desc);
        }
    }
    public class Printersclass
    {
        public string Name { get; set; }
        public string Desc { get; set; }

        public override string ToString()
        {
            return string.Format("{0} ({1})", Name, Desc);
        }
    }

谢谢你的MSDN链接！你能为代码添加一个解释吗？这是一个非常有趣的答案。如果您只需要姓名，则接受的答案是正确的。如果您需要其他数据，使用对win32_打印机的查询要比执行此调用慢得多。这是获取所有信息的最佳答案。您的演示也在ASP.NET中吗？从未想过在System.Drawing中搜索此内容！

using System.Collections.Generic;
using System.Linq;
using System.IO.Ports;
using System.Drawing.Printing;

    public class Miclass
    {
        private void AllViews()
        {
            List<PortClass> ports = new List<PortClass>();
            List<Printersclass> Printersfor = new List<Printersclass>();
            string[] portnames = SerialPort.GetPortNames();
            /*PORTS*/
            for (int i = 0; i < portnames.Count(); i++)
            {
                ports.Add(new PortClass() { Name = portnames[i].Trim(), Desc = portnames[i].Trim() });
            }
            /*PRINTER*/
            for (int i = 0; i < PrinterSettings.InstalledPrinters.Count; i++)
            {
                Printersfor.Add(new Printersclass() { Name = PrinterSettings.InstalledPrinters[i].Trim(), Desc = PrinterSettings.InstalledPrinters[i].Trim() });
            }
        }
    }
    public class PortClass
    {
        public string Name { get; set; }
        public string Desc { get; set; }

        public override string ToString()
        {
            return string.Format("{0} ({1})", Name, Desc);
        }
    }
    public class Printersclass
    {
        public string Name { get; set; }
        public string Desc { get; set; }

        public override string ToString()
        {
            return string.Format("{0} ({1})", Name, Desc);
        }
    }
