让更多PaperSource细节 [英] getting additional PaperSource details

问题描述

我试图让各种打印机的托盘正确的细节但是所遇到的一个问题。经过一番研究，我添加了ReachFramework.dll也

I'm trying to get the correct details of trays of various printers however have come across a problem. After a bit of research I've added the ReachFramework.dll and also

using System.Drawing.Printing;

要获得托盘的名字我运行下面的code打印机...

To get the names of the trays for a printer I run the following code...

PrintDocument printDocument = new PrintDocument();
printDocument.PrinterSettings.PrinterName = "<Windows Printer Name>";

foreach (PaperSource paperSource in printDocument.PrinterSettings.PaperSources)
{
    Console.WriteLine(paperSource.ToString());
}

...取代Windows打印机名称。对于某些打印机它的伟大工程，我得到类似如下的输出...

...replacing 'Windows Printer Name'. For some printers it works great and I get something like the following output...

[PaperSource Auto Tray Select Kind=AutomaticFeed]
[PaperSource Tray 1 Kind=Upper]
[PaperSource Tray 2 Kind=Middle]
[PaperSource Tray 3 Kind=Lower]
[PaperSource Bypass Tray Kind=Manual]

这是你所期望的。然而，对于某些打印机出现以下...

Which is what you would expect. However for some printers I get the following...

[PaperSource  Automatically Select Kind=FormSource]
[PaperSource  Printer auto select Kind=Custom]
[PaperSource  Manual Feed in Tray 1 Kind=Custom]
[PaperSource  Tray 1 Kind=Custom]
[PaperSource  Tray 2 Kind=Custom]
[PaperSource  Tray 3 Kind=Custom]
[PaperSource Unspecified Kind=Custom]
[PaperSource Plain Kind=Custom]
[PaperSource HP Matte 90g Kind=Custom]
[PaperSource Light 60-74g Kind=Custom]
[PaperSource Bond Kind=Custom]
[PaperSource Recycled Kind=Custom]
[PaperSource HP Matte 105g Kind=Custom]
[PaperSource HP Matte 120g Kind=Custom]
[PaperSource HP Soft Gloss 120g Kind=Custom]
[PaperSource HP Glossy 130g Kind=Custom]
... Additional 20 lines ...

该打印机返回36盘，但只有前6个是有效的纸盒类型。此外，打印机仅配备了2个标准托盘，所以托盘3'也不存在。

This printer returned 36 trays but only the first 6 are valid tray types. Additionally the printer is only equipped with 2 standard trays, so 'Tray 3' is doesn't exist either.

所以我的问题是这样的。我怎样才能过滤此列表，以便只有正确的托盘都出现了？

So my question is this. How can I filter this list so only the correct trays are showing?

推荐答案

发现改变的foreach并增加了部分答案的，如果像下面的语句...

Found a partial answer by changing the foreach and adding an if statement like the following...

foreach (PaperSource paperSource in printDocument.PrinterSettings.PaperSources)
{
    if (paperSource.RawKind < 1000)
    {
        Console.WriteLine(paperSource.ToString());
    }
}

这将产生以下输出...

This produces the following output...

[PaperSource  Automatically Select Kind=FormSource]
[PaperSource  Printer auto select Kind=Custom]
[PaperSource  Manual Feed in Tray 1 Kind=Custom]
[PaperSource  Tray 1 Kind=Custom]
[PaperSource  Tray 2 Kind=Custom]
[PaperSource  Tray 3 Kind=Custom]

虽然不是理想它并解决问题的一部分。但是，它没有解决根本不存在有效的托盘的问题。

While not ideal it does solve the part of the problem. It doesn't however solve the issue of valid trays that do not exist.
