PrintDocument，更换打印机纸盘
问题说明
你好
我想更换正在使用的打印机的纸盘.我正在使用PrintDocument类，而以下是我正在使用的代码
Hello
I want to change the tray of the printer I am using. I am using the PrintDocument class and the following is the code im working with
for (int i = 0; i < printDocument.PrinterSettings.PaperSources.Count; i )
{
printDocument.DefaultPageSettings.PaperSource.SourceName = printerSettings.PaperSources[i].SourceName;
printDocument.Print();
}
即使实际的打印机只有3个，打印机的纸张来源也似乎是17个.并且每次我尝试在此循环中更改papersource时，它都不会更改，在分配后SourceNam会保持自动选择"状态.
我无法更改printDocument的SourceName.
任何帮助将不胜感激
谢谢你
The printer paper sources appear to be 17 even though the actualy printer have 3 only. And every time i try to change the papersource in this loop, it doesnt change, the SourceNam stays "Automatically Selected" after the assignment.
I am not able to change the SourceName of the printDocument.
Any assistance would be appreciated
thank you

你好，
你尝试过吗?
Hello,
Have you tried?
printDocument.DefaultPageSettings.PaperSource = printerSettings.PaperSources[i];
在MSDN上有一篇文章演示了应如何做:
