如何使用Web处理程序创建PDF?

问题描述：

我对网络处理程序的了解很少.我所知道的是，Web处理程序用于创建一些动态文件创建目的.

I have pretty less knowledge in web handlers. All I know is web handlers are used for creating some dynamic file creation purpose.

我也知道如何添加Web处理程序.

And also I know how to add the Web handlers.

但是，我需要在ASP.NET项目中使用Web处理程序来创建PDF.

But, I need to use web handlers in my ASP.NET project for PDF creation purpose.

答

您可以使用HTTP处理程序来提供PDF，如下所示:

You can have a HTTP handler to serve out your PDFs like this:

public void ProcessRequest (HttpContext context) {

    // Get your file as byte[]
    string filename = "....file name.";
    byte[] data = get your PDF file content here;

    context.Response.Clear();
    context.Response.AddHeader("Pragma", "public");
    context.Response.AddHeader("Expires", "0");
    context.Response.AddHeader("Content-Type", ContentType);
    context.Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", filename));
    context.Response.AddHeader("Content-Transfer-Encoding", "binary");
    context.Response.AddHeader("Content-Length", data.Length.ToString());
    context.Response.BinaryWrite(data);
    context.Response.End(); 

}
