推荐答案

在Gridview中添加



< asp：templatefield headertext =Downloadxmlns：asp =＃unknown>

< itemtemplate>

< asp：imagebutton id =btnDownloadrunat =servertooltip =Downloadimageurl =〜/ Images / icon / Download.ico>

CommandName =DownloadCommandArgument ='< ;％＃Bind（ReportName）％>'/>



< itemstyle width =10％>







在行命令中添加以下代码



protected void gvReport_RowCommand（object sender，GridViewCommandEventArgs e）

{

尝试

{

if（e.CommandName ==Download）

{

string CommandArgument = e .CommandArgument.ToString（）;





string path =./;

string serverPath = HttpContext.Current.Server.MapPath（path）;

string pdfpath = serverPath +QuarterlyReports\\+ CommandArgument +。pdf;



//Response.Redirect（fileName）;

Response.ContentType =appl ication / pdf;

Response.AppendHeader（Content-Disposition，附件; filename =+ Path.GetFileName（pdfpath））;

Response.TransmitFile（pdfpath）;

//HttpContext.Current.ApplicationInstance.CompleteRequest();

Response.End（）;



}

catch（例外情况）

{



}

Add in Gridview

<asp:templatefield headertext="Download" xmlns:asp="#unknown">
<itemtemplate>
<asp:imagebutton id="btnDownload" runat="server" tooltip="Download" imageurl="~/Images/icon/Download.ico">
CommandName="Download" CommandArgument='<%# Bind("ReportName") %>' />

<itemstyle width="10%">



Add below code in row command

protected void gvReport_RowCommand(object sender, GridViewCommandEventArgs e)
{
try
{
if (e.CommandName == "Download")
{
string CommandArgument = e.CommandArgument.ToString();


string path = "./";
string serverPath = HttpContext.Current.Server.MapPath(path);
string pdfpath = serverPath + "QuarterlyReports\\" + CommandArgument + ".pdf";

//Response.Redirect(fileName);
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(pdfpath));
Response.TransmitFile(pdfpath);
//HttpContext.Current.ApplicationInstance.CompleteRequest();
Response.End();

}
catch (Exception ex)
{

}

protected void gd_cat_RowCommand（object sender，GridViewCommandEventArgs e）

{

if（e.CommandName ==downLoad）

{

DataTable dt = new DataTable（）;

Int32 id = Convert.ToInt32（e.CommandArgument）;

p.Admin_Flag = 8;

p.Id = id;

p.Post_Date = System.DateTime.Now.Date;

dt = b.Job_Applied_GridShow（p）;

if（dt.Rows.Count> 0）

{

string filepath =〜/+ dt.Rows [0] [file_path]。ToString（）;





// ........ ................................................ >
string path = Server.MapPath（filepath）;

//从服务器获取物理文件路径

string name = Path.GetFileName（path）;

//获取文件名

string ext = Path.GetExtension（path）;

//获取文件扩展名

string type =;

//根据文件扩展名设置已知类型

if（ext！= null）

{

开关（ext.ToLower（））

{

//案例.htm：

//案例.html：

// type =text / HTML;

// break;

// case.txt：

// type =text / plain;

// break;

// case .GIF：

// type =image / GIF;

// break;

case.pdf：

type =Application / pdf;

break;

case.doc：

case.rtf ：

type =Application / msword;

break;

默认值：

type = ;

休息;

}

}

Response.AppendHeader（content-disposition，附件; filename =+ name）;

if（type！=）

{

Response.ContentType = type;

Response.WriteFile（路径）;

Response.End（）; //为用户提供POP文件下载

}



}



}

}

protected void gd_cat_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "downLoad")
{
DataTable dt = new DataTable();
Int32 id = Convert.ToInt32(e.CommandArgument);
p.Admin_Flag = 8;
p.Id = id;
p.Post_Date = System.DateTime.Now.Date;
dt = b.Job_Applied_GridShow(p);
if (dt.Rows.Count > 0)
{
string filepath = "~/" + dt.Rows[0]["file_path"].ToString();


//.......................................................
string path = Server.MapPath(filepath);
//get physical file path from server
string name = Path.GetFileName(path);
//get file name
string ext = Path.GetExtension(path);
//get file extension
string type = "";
// set known types based on file extension
if (ext != null)
{
switch (ext.ToLower())
{
// case ".htm":
// case ".html":
// type = "text/HTML";
// break;
// case ".txt":
// type = "text/plain";
// break;
// case ".GIF":
// type = "image/GIF";
// break;
case ".pdf":
type = "Application/pdf";
break;
case ".doc":
case ".rtf":
type = "Application/msword";
break;
Default:
type = "";
break;
}
}
Response.AppendHeader("content-disposition", "attachment; filename=" + name);
if (type != "")
{
Response.ContentType = type;
Response.WriteFile(path);
Response.End(); //give POP to user for file downlaod
}

}

}
}
