列出可用的网络打印机(也未安装) [英] List available network printers (non-installed as well)

问题描述

这意味着我能够枚举所有打印机(网络打印机和本地打印机)，但前提是它们都安装在我的PC上

Meaning i am able to enum all printers (network and local) but ONLY if they are installed on my PC

但是，我希望能够列出未安装的那些，并且可以使用(内置Windows的)添加打印机"对话框看到.

However i want to be able to list those that are not installed and can be seen by using (windows built-in) ADD PRINTER dialog.

是否有可能，因为我在浏览各种论坛/论坛(包括stackexchange)时找不到任何有用的信息.

Is it even possible as i couldn't find anything useful browsing various forums/boards including stackexchange.

意思是我也尝试了内置的.NET类和WMI(SELECT * from Win32_Printer)，但显然它们仅列出了已安装的打印机.

Meaning i tried the built-in .NET classes and WMI as well (SELECT * from Win32_Printer) but obviously they list only the installed printers.

非常感谢您

请注意，建议的答案并不针对未安装的打印机，而仅针对已安装的打印机.我已经能够列出这些.谢谢

please notice that suggested answer does not address non-installed printers but rather only installed ones. I am already able to list those. Thx

推荐答案

我不相信.NET中有任何功能可以做到这一点，您将需要进行本机调用. 这是MSDN页面关于如何枚举网络资源，您需要做的是P/调用WNetEnumResource函数以获取

I do not believe there is anything in .NET that can do this, you will need to make a native call. Here is the MSDN page about how to enumerate network resources, what you will need to do is P/Invoke the WNetEnumResource function to get NETRESOURCE objects back.

您正在寻找dwType为RESOURCETYPE_PRINT的对象，找到它们时，请选中lpRemoteName以获取打印机的名称.

You are looking for objects that have a dwType of RESOURCETYPE_PRINT, when you find them you check lpRemoteName to get the name of the printer.

此处是 a的链接示例代码段来实现其用法(即使URL指出它是VB，代码也使用C#).我将其张贴在这里，但是页面上的注释明确地不允许未经作者许可而复制和粘贴脚本.

Here is a link to a example snippet implementing its use (Even though the URL states it is VB the code is in C#). I would post it here but the note on the page expressly does not allow copying and pasting of the script without permission of the author.
