1.创建一个Winform窗体,窗体分为“数据上传”和“数据读取”两部分;
2.在SQL Server数据库中创建一个名为PeopleInformation的数据表,表中分配三个字段,分别为:ID、Name、Photo;
3.将ID字段设置为主键,自增
图片上传的代码:
//通过数据流读取本地的图片信息 FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read); byte[] bt = new byte[fs.Length]; fs.Read(bt, , bt.Length); fs.Close(); //打开数据库的连接 string strconn = @"Data Source=LONG-PC\;Initial Catalog=PRACTICE;User ID=istrive;Password=istrive"; SqlConnection conn = new SqlConnection(strconn); conn.Open(); //将信息上传到 SQL Server string strcmd = "insert into PeopleInformation (Name,Photo) values (@name,@photo)"; SqlCommand cmd = new SqlCommand(); cmd.Connection = conn; cmd.CommandText = strcmd; cmd.Parameters.Add(new SqlParameter("@name", txtUpload.Text)); cmd.Parameters.Add(new SqlParameter("@photo",bt)); cmd.ExecuteNonQuery(); //关闭数据库连接 conn.Close();
图片读取的代码:
//打开数据库连接 string strcoon = @"Data Source=LONG-PC\;Initial Catalog=PRACTICE;User ID=istrive;Password=istrive ;Connect Timeout=5"; SqlConnection conn = new SqlConnection(strcoon); conn.Open(); //查询数据库 string strcmd = "select Name,Photo from PeopleInformation where Name = @name"; SqlCommand cmd = new SqlCommand(strcmd, conn); cmd.Parameters.Add(new SqlParameter("@name", name)); SqlDataAdapter adap = new SqlDataAdapter(cmd); DataTable dt = new DataTable(); cmd.ExecuteNonQuery(); adap.Fill(dt); //将图片信息从 DataTable 以数据流的形式读取 ) { MemoryStream ms = ]["Photo"]); picRead.Image = Image.FromStream(ms, true); }
