asp.net将图片转成二进制存入数据库

一、代码如下

 int code = int.Parse(this.TextBox1.Text);//图片编码
        string value = this.FileUpload1.PostedFile.FileName.ToString();//图片路径
        string type = value.Substring(value.LastIndexOf(".") + 1);
        FileStream fs = File.OpenRead(value);
        byte[] content = new byte[fs.Length];
        fs.Read(content, 0, content.Length);
        fs.Close();

        string sqlconfrom = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["sqlConnectionStrings"].ToString();
        SqlConnection con = new SqlConnection(sqlconfrom);
        string sql = " insert into Image_Table values ( '1',@content,@code ) ";

        SqlCommand cmd = new SqlCommand(sql, con);
        cmd.Parameters.Add(new SqlParameter("@content", SqlDbType.Image));
        cmd.Parameters["@content"].Value = content;

        cmd.Parameters.Add(new SqlParameter("@code", SqlDbType.Int));
        cmd.Parameters["@code"].Value = code;
        con.Open();
        int result = cmd.ExecuteNonQuery();
        if (result > 0)
        {
            Response.Write("插入成功！");
        }
        con.Close();
