我已经上传了文件到服务器,并把路径什么的存到了数据库.
请问怎么实现下载?

很简单，建立一个链接指向要下载的文件就可以了

protected void btnFileDown_Click(object sender, EventArgs e)
    {
        SKK.BBL.NewClothList client = new SKK.BBL.NewClothList();
        Button btn = sender as Button;
        int CC_id = Convert.ToInt32();
        DataSet ds = client.NewClothSelectByID(CC_id) as DataSet;
        string FileName = ds.Tables[0].Rows[0]["Annex"].ToString();
        if (string.IsNullOrEmpty(FileName))
        {
            (this, "此文件没在系统里，请与有关人员联系");
        }
        else
        {
             file = new (FileName);
            string ct = Response.ContentType;
            Response.Clear();
            Response.AppendHeader("Content-Disposition", "attachment; filename=" + file.Name);
            Response.AppendHeader("Content-Length", file.Length.ToString());
            Response.ContentType = "application/octet-stream";
            Response.WriteFile(file.FullName);
            Response.End();
            file = null;
            Response.Clear();
            Response.ContentType = ct;
        }
    }
上面是下载的代码,你自己去看看吧!!!

SKK.BBL.NewClothList client = new SKK.BBL.NewClothList();
是什么啊

不明白

要加什么头文件?

难道不用从数据库读出什么吗?

代码不是很明白.
我主要是不明白,点击下载按钮时怎么弹出那个保存的框之类的

file = new (FileName);
            string ct = Response.ContentType;
            Response.Clear();
            Response.AppendHeader("Content-Disposition", "attachment; filename=" + file.Name);
            Response.AppendHeader("Content-Length", file.Length.ToString());
            Response.ContentType = "application/octet-stream";
            Response.WriteFile(file.FullName);
            Response.End();
            file = null;
            Response.Clear();
            Response.ContentType = ct;
你看这些代码了,其他跟下载没关系的.那是我从数据库中读取出来的代码
