推荐答案

如果你能通过网络浏览器获取文件，那么你可以尝试WebRequest类从代码中获取文件。以下是使用WebRequest类的示例：



http://msdn.microsoft.com/en-us/library/456dfw4f（v = vs.110）.aspx [ ^ ]

If you are able to get the file through a web browser, then you can try WebRequest class to fetch the file from code. Here is an example of using WebRequest class:

http://msdn.microsoft.com/en-us/library/456dfw4f(v=vs.110).aspx[^]

您应该尝试下一个示例：

You should try like in the next example:

try
           {
               Response.Clear();
               Response.ClearContent();
               //
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=" + this.FileName);
               //
Response.Cache.SetCacheability(System.Web.HttpCacheability.Public);
               string filePath = string.Format("{0}\\{1}", Server.MapPath(this.VirtualPath), this.FileName));
               if (System.IO.File.Exists(filePath))
               {
                   Response.TransmitFile(filePath);
               }
               else
               {
                   Response.Write("File Not Found!");
               }
               //
               Response.End();
           }
           catch (Exception ex)
           {
            //...TO DO!   
           }

在你的Web.config中你应该有下一个可以访问的设置 PDF文件夹命名内容给所有用户：

An in your Web.config you should have the next setting that will make accessible the "PDF folder" named "Content" to all users:

<location path="Content">
    <system.web>
      <authorization>
        <allow users="*" />
      </authorization>
    </system.web>
  </location>
