C＃-WEB：打开保存在数据库中的PDF [英] C#-WEB:Open a PDF saved in the database
问题描述
在我的程序中，用户可以上传保存在SQL Server中的PDF文件。但是当我尝试检索文件时，它就不会打开。我使用以下代码：
_ObjUC = new UserControls（）;
DataTable dt = new DataTable（）;
_ObjUC.DocumentID = Request.QueryString [" id"]。ToString（）。Trim（）;
dt = _ObjUC.getPDFdocument（_ObjUC.DocumentID）;
byte [] buffer =（byte []）dt.Rows [0] [" document_content"];
Response.ContentType =" application / pdf";
Response.AddHeader（" Content-Type"，" application / pdf"）;
Response.AddHeader（" content-disposition"，" inline; filename = file.pdf"）;
MemoryStream PageData = new MemoryStream（buffer）;
PageData.WriteTo（Response.OutputStream）;
我们使用共享开发环境。有趣的是，它适用于我的同事comp但不适用于我的同事。我们都用户IE 7.0。我在这里做错了吗？还有另一种方法吗？
In my progr, users can upload PDF files which are saved in SQL Server. But when I try to retrieve the file, it just won''t open. I am using the following code:
_ObjUC = new UserControls();
DataTable dt = new DataTable();
_ObjUC.DocumentID = Request.QueryString["id"].ToString().Trim();
dt = _ObjUC.getPDFdocument(_ObjUC.DocumentID);
byte[] buffer = (byte[])dt.Rows[0]["document_content"];
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Type", "application/pdf");
Response.AddHeader("content-disposition", "inline;filename=file.pdf");
MemoryStream PageData = new MemoryStream(buffer);
PageData.WriteTo(Response.OutputStream);
We use a shared development environment. The funny thing is that it works on my collegues comp but not on mine. We both user IE 7.0. Am I doing something wrong here? Is there an alternate way?
推荐答案
当你说不打开时你什么意思？怎么了？你有一个保存对话框并且文件已损坏，或者根本不会下载？
When you say "won''t open" what do you mean? What happens? Do you get a save dialog and the file is corrupted, or will it not download at all?
No ...我得到的只是一个空白屏幕
No ... all I get is a blank screen
