问题描述

Microsoft Windows 10 附带 Microsoft Print To PDF 打印机，可以将内容打印到 PDF 文件.它会提示下载文件名.

Microsoft Windows 10 comes with a Microsoft Print To PDF printer which can print something to a PDF file. It prompts for the filename to download.

如何通过 C# 以编程方式对此进行控制，使其不提示输入 PDF 文件名，而是保存到我提供的某个文件夹中的特定文件名?

How can I programmatically control this from C# to not prompt for the PDF filename but save to a specific filename in some folder that I provide?

这用于以编程方式将大量文档或其他类型的文件打印到 PDF 的批处理.

This is for batch processing of printing a lot of documents or other types of files to a PDF programmatically.

推荐答案

要使用 Microsoft Print to PDF 打印机打印 PrintDocument 对象而不提示输入文件名，请点击此处是纯代码的方式来做到这一点:

To print a PrintDocument object using the Microsoft Print to PDF printer without prompting for a filename, here is the pure code way to do this:

// generate a file name as the current date/time in unix timestamp format
string file = (DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds.ToString();

// the directory to store the output.
string directory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

// initialize PrintDocument object
PrintDocument doc = new PrintDocument() {
    PrinterSettings = new PrinterSettings() {
        // set the printer to 'Microsoft Print to PDF'
        PrinterName = "Microsoft Print to PDF",

        // tell the object this document will print to file
        PrintToFile = true,

        // set the filename to whatever you like (full path)
        PrintFileName = Path.Combine(directory, file + ".pdf"),
    }
};

doc.Print();

您也可以将此方法用于其他另存为文件类型的打印机，例如Microsoft XPS打印机

You can also use this method for other Save as File type printers such as Microsoft XPS Printer
