我正在开发一个网站，我在其中上传文档并存储在文件夹中。上载文档工作正常，但下载代码无效。我需要从文件夹下载文件。
protected void btnDownload_Click(object sender, EventArgs e)
{
lblresume.Text = "~/Student_Resume/" + fuResume.FileName.ToString();
if (lblresume.Text != string.Empty)
{
string filePath = lblresume.Text;
Response.ContentType = "doc/docx";
Response.AddHeader("Content-Disposition", "attachment;filename=\"" + filePath + "\"");
Response.TransmitFile(Server.MapPath(filePath));
Response.End();
}
}
尝试这个
protected void btnDownload_Click(object sender, EventArgs e)
{
lblresume.Text = "~/Student_Resume/" + fuResume.FileName.ToString();
if (lblresume.Text != string.Empty)
{
WebClient req = new WebClient();
HttpResponse response = HttpContext.Current.Response;
string filePath = lblresume.Text;
response.Clear();
response.ClearContent();
response.ClearHeaders();
response.Buffer = true;
response.AddHeader("Content-Disposition", "attachment;filename=Filename.extension");
byte[] data = req.DownloadData(Server.MapPath(filePath));
response.BinaryWrite(data);
response.End();
}
}
