数据库有这些字段： id, imgData, type, description, imgSize
id是自增长

<%@Page language="C#" %>
<%@import namespace="System.IO"%>
<%@import namespace="System.Data"%>
<%@import namespace="System.Data.SqlClient"%>
<script language="C#" runat="server">
public void Button_Submit(Object o, EventArgs e)
{
HttpPostedFile upFile = up_file.PostedFile;
int iFileLength = upFile.ContentLength;
try
{
if(iFileLength == 0)
{
txtMess.Text = "请选择要上传的文件！";
}
else
{
Byte[] FileByteArray = new Byte[iFileLength];
Stream StreamObject = upFile.InputStream;
StreamObject.Read(FileByteArray, 0, iFileLength);
SqlConnection conn = new SqlConnection("server=yy;uid=sa;pwd=;database=pany");
string sql = "insert into t_imgs (imgData, type, description, imgSize) values "
+ "(@Image, @ContentType, @ImageDescription, @ImgSize)";
SqlCommand cmd = new SqlCommand(sql, conn);
cmd.Parameters.Add("@Image", SqlDbType.Binary, iFileLength).Value = FileByteArray;
cmd.Parameters.Add("@ContentType", SqlDbType.VarChar, 50).Value = upFile.ContentType;
cmd.Parameters.Add("@ImageDescription", SqlDbType.VarChar, 200).Value = txtDesc.Text;
cmd.Parameters.Add("@ImgSize", SqlDbType.BigInt, 8).Value = upFile.ContentLength;
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
txtDesc.Text = "";
txtMess.Text = "OK!你已经成功上传了类型的文件";
}
}
catch(Exception ex)
{
txtMess.Text = ex.Message.ToString();
}
}

</script>

<html>
<head>
<title>上传图片</title>

if(fileUpLoad.PostedFile.ContentLength==0)
return false;
string sFileName= fileUpLoad.PostedFile.FileName ;
//文件名
sFileName =Path.GetFileName(sFileName);
//保存路径
string scFileName_Old=Path.GetFileNameWithoutExtension(sFileName);
string sDirFile=Server.MapPath(".")System.Configuration
.ConfigurationSettings.AppSettings["FTPDir"].ToString(); //"\\Attachmant\\";

if(!Directory.Exists(sDirFile))
Directory.CreateDirectory(sDirFile);
string sFileNameNew=sFileName;
sFileNameNew=scFileName_Old+sNewID+Path.GetExtension(sFileName).ToString();
fileUpLoad.PostedFile.SaveAs(sDirFile+sFileNameNew) ;
//判断文件是否上传成功
if (!File.Exists(sDirFile+sFileNameNew))
return false;
