写图片c:\1.jpg到表cinfo中 复制代码 代码如下: private static void AddCinfo() { string strSql = "insert into cinfo (srvtitle,csttitle,introduction,logo) values
(@srvtitle,@csttitle,@introduction,@logo)"; SqlParameter[] parms = { new SqlParameter("@srvtitle",SqlDbType.VarChar,30), new SqlParameter("@csttitle",SqlDbType.VarChar,30), new SqlParameter("@introduction",SqlDbType.NVarChar,500), new SqlParameter("@logo",SqlDbType.Image) }; parms[0].Value = "旅业互动"; parms[1].Value = "lyhd"; parms[2].Value = "简介";
string filePath = @"c:\1.jpg"; FileStream fs = File.OpenRead(filePath);
byte[] content = new byte[fs.Length];
fs.Read(content, 0, content.Length);
fs.Close();
parms[3].Value = content;
DBHelper.ExecuteNonQuery(CommandType.Text, strSql, parms); } 读取图片的页面 test.aspx 复制代码 代码如下: protected void Page_Load(object sender, EventArgs e) { string strSql = "select * from cinfo where id=1"; SqlDataReader reader=DBHelper.ExecuteReader(CommandType.Text, strSql, null); if(reader.Read()) { byte[] c=(byte[])reader["logo"]; Response.BinaryWrite(c); } } 用来显示图片的页面 test2.aspx 复制代码 代码如下: <img src="test.aspx" />
