你愿意做成把文件的内容写到数据库的吗？
用这个控件：
<asp:FileUpload ID="FileUpload" runat="server" Width="437px" />
//In
model.FileName = this.FileUpload.FileName;
model.FileContent = this.FileUpload.FileBytes;
model.FileType = this.FileUpload.PostedFile.ContentType;
//Out
在把文件名给展现出来的旁边多个按钮
protected void lbtnFile_Click(object sender, EventArgs e)
{
InformInfo model = _facade.GetModel(Convert.ToInt32(this.lblId.Text));
Response.Buffer = true;
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(model.FileName));
Response.AddHeader("Content-Type", model.FileType);
Response.BinaryWrite(model.FileContent);
Response.End();
}

<div onclick=\"OpenObject('" + Server.UrlEncode(URL) + "')\"><a>" + FileName + "</a></div>
private void openFile()
{
string FilePath = Server.MapPath(FileURL);
FileInfo fi = new FileInfo(FilePath);
FileStream fs = new FileStream(FilePath, FileMode.Open);
byte[] bytes = new byte[(int)fs.Length];
fs.Read(bytes, 0, bytes.Length);
fs.Close();
Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(fi.Name, System.Text.Encoding.UTF8).Replace("+", " "));
Response.BinaryWrite(bytes);
Response.End();
}
openFile()可以在页面回调加以区别后调用
