在百度上找了许多PDF文件打印，但是符合我需求的打印方式还没看到，所以根据看了的范例后，研究了一下，做出来符合自己需求的打印方式分享一下。

1、先要引用一个插件，可以从网上搜索下载就好

2、前端JS，比较简单一句代码，重点放在后台操作。

3、后台代码。

1 public class PdfResult:ActionResult 2 { 3         private string FileName; 4         public event DocRenderHandler DocRenderEvent; 5         public delegate void DocRenderHandler(ref Document Doc); 6  7         /// 
 8         /// 将FileName赋值一次 9         /// 
10         /// 11         public PdfResult(string FileName)12         {13             this.FileName = FileName;14         }15 16         ///
