用 C# 打印 PDF 文件
在您的 .NET 应用程序中使用 C# 自动打印 PDF 文件是简单的。
- 创建一个对象的 PdfViewer 班级。
- 输入 PDF 文档。
- 打印 PDF 文件。
下面是一个代码剪辑,展示如何使用C#打印PDF文件:

| //Create PdfViewer object | |
| PdfViewer viewer = new PdfViewer(); | |
| //Open input PDF file | |
| viewer.BindPdf(dataDir + "Test.pdf"); | |
| //Print PDF document | |
| viewer.PrintDocument(); | |
| //Close PDF file | |
| viewer.Close(); |
以 C# 打印多个 PDF 文件
如果您的业务需要打印多个PDF文件,Aspose.PDF for .NET API 可以帮助简化过程,而不是单独打印每个文件,您可以使用列表以有效地打印多个文件。
- 初步 A
List<string>保持文件名。 - 将PDF文件添加到列表中。
- 下载每个PDF文件。
- 打印多个 PDF 文件。
下面的代码剪辑描述了如何使用C#打印多个PDF文件:

| var files = new List<string>(); | |
| files.Add(dataDir + "First.pdf"); | |
| files.Add(dataDir + "Second.pdf"); | |
| foreach (String file in files) | |
| { | |
| //Create PdfViewer object | |
| PdfViewer viewer = new PdfViewer(); | |
| //Open input PDF file | |
| viewer.BindPdf(file); | |
| //Print PDF document | |
| viewer.PrintDocument(); | |
| //Close PDF file | |
| viewer.Close(); | |
| } |
用 C# 打印 PDF 的具体页面
Aspose.PDF API 允许您从 PDF 文档中打印特定页面. 要做到这一点,您必须指定您想要打印的页面序列。

打印页面范围到不同纸质来源使用C#
在某些情况下,您可能希望将相同的 PDF 文档的不同页面打印到不同的纸质来源。 例如,您可以从一个字符串打印覆盖页面,然后从另一个字符串打印后面的页面。
- 启动一个对象的 PdfViewer 班级。
- 使用 The PdfQueryPage设置 活动代表。
- 设置页面和打印设置。
- 打电话给 印刷文件WithSettings 方法。
下面是一个代码剪辑,显示如何向不同的纸质来源打印不同的页面范围:
