asp.net将图片转成二进制存入数据库
一、代码如下
1 int code = int.Parse(this.TextBox1.Text);//图片编码 2 string value = this.FileUpload1.PostedFile.FileName.ToString();//图片路径 3 string type = value.Substring(value.LastIndexOf(".") + 1); 4 FileStream fs = File.OpenRead(value); 5 byte[] content = new byte[fs.Length]; 6 fs.Read(content, 0, content.Length); 7 fs.Close(); 8 9 string sqlconfrom = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["sqlConnectionStrings"].ToString(); 10 SqlConnection con = new SqlConnection(sqlconfrom); 11 string sql = " insert into Image_Table values ( '1',@content,@code ) "; 12 13 SqlCommand cmd = new SqlCommand(sql, con); 14 cmd.Parameters.Add(new SqlParameter("@content", SqlDbType.Image)); 15 cmd.Parameters["@content"].Value = content; 16 17 cmd.Parameters.Add(new SqlParameter("@code", SqlDbType.Int)); 18 cmd.Parameters["@code"].Value = code; 19 con.Open(); 20 int result = cmd.ExecuteNonQuery(); 21 if (result > 0) 22 { 23 Response.Write("插入成功!"); 24 } 25 con.Close();
昨日龌龊不足夸,今日放荡思无涯。
