SqlConnection scn = new SqlConnection("Data Source=10.114.72.5;Initial Catalog=VehicleDB;User ID=sa;Password=4600dell");
SqlCommand cmd = scn.CreateCommand();
cmd.CommandText = "select FuJian_img from t_CheckRecord where CheckPlanID_i=3 and VehicleID_i=130 ";
SqlDataAdapter sda = new SqlDataAdapter();
sda.SelectCommand = cmd;
DataTable dt = new DataTable();
sda.Fill(dt);

byte[] file = (byte[])dt.Rows[0]["FuJian_img"];

string filename = "我爱哈哈.rar";

Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/octet-stream";
string headerstring = "attachment; filename=";
//对中文的文件名进行编码，这样客户端可以看到正确的中文文件名称，否则为乱码
filename = System.Web.HttpUtility.UrlEncode(Response.ContentEncoding.GetBytes(filename));

Response.AppendHeader("Content-Disposition", headerstring + filename);
Response.BinaryWrite(file);
Response.End();

首先 从库中获取二进制流，
接着 将二进制流写入到HTTP输出流，这样客户端会收到这个输出流，并显示

--照着做吧

看错了
想head中传送文档？？？？
怎么显示

[一品梅]

可以，例如添加js:

 protected void Page_Load(object sender, EventArgs e)
15    {
16        string script = @"<script language='javascript' type='text/javascript'>document.write('this client script is created by back end code, and it is placed in head tag!')</script>";
17        HtmlHead header = Page.Header;
18        header.InnerHtml = script;
19    }

想干啥?

1.在页面建一个标签的形式比如：<%=head%>
2.后台代码取出head
3.注意head定义为public！
