问题描述
我需要System.Drawing.Printing.PaperKind得到纸张大小。是否有任何预定义的值？我不想硬编码或计算的纸张尺寸，我只是想获得它编程。谢谢你。
I need to get paper size by System.Drawing.Printing.PaperKind. Are there any predefined values? I don't want to hardcode or calculate paper sizes, I just want to get it programmatically. Thanks.
推荐答案
预设值的子集可以通过遍历一个 PrinterSettings.PaperSizes 集合。
A subset of predefined values can be had by iterating over a PrinterSettings.PaperSizes collection.
我们的应用程序，用户选择一台打印机，为我们提供了一个的对象。在 PrinterSettings 包含为打印机支持 PAPERSIZE 的列表 - 不是万能的（注意，XPS文档驱动程序（WIN7）支持所有规格）。
Our application has the user select a printer, providing us with a PrinterSettings object. Contained within PrinterSettings is a list of PaperSize's supported by the printer - not everything (note that the XPS Document Driver (win7) supports all sizes).
在我们的例子中支持的尺寸的这个子集是我们所需要的。指定的用户 PaperKind 传递给我们的打印代码，并经过我们的 PrinterSettings 对象直至找到用户选择或放弃，并使用默认值。
In our case this subset of supported sizes is all we need. A user specified PaperKind is passed to our printing code, and it goes through our PrinterSettings object until it either finds the user's selection or gives up and uses a default.
在下面的例子中，你可以看到 PAPERSIZE 对象是正确的。填写
In the example below you can see that the PaperSize objects are correctly filled.
PrinterSettings settings = new PrinterSettings();
foreach (PaperSize size in settings.PaperSizes)
Debug.WriteLine(size);
这只是一个子集，但也许这也够你。在.NET中印API是真的不清楚，MSDN是不是真的有很大帮助......希望它让你在正确的轨道上！
It's only a subset, but maybe that's also enough for you. the printing APIs in .NET are really unclear and msdn isn't really much help... Hopefully it puts you on the right track!
