如何存取圖檔到資料庫(SQL Server)

以二進制形式通過AppendChunk()方法存到資料庫裡,再通過Image類的FromStream()方法将圖檔顯示到PictureBox控件中.

AppendChunk()方法:

StringBuilder strSql = new StringBuilder();

                strSql.Append("insert into cpic values(@車牌号,@車圖)");

                SqlCommand cmd = new SqlCommand(strSql.ToString(), conn);

                cmd.Parameters.Add("@車牌号", SqlDbType.Text).Value = cph;

                cmd.Parameters.Add("@車圖", SqlDbType.Binary).Value = pic;

Image類的FromStream()方法:

                byte[] pic = (byte[])dt.Rows[*][*];

                //MessageBox.Show(dt.Rows[*][*].ToString());

                MemoryStream ms = new MemoryStream(pic);

                this.pictureBox1.Image = Image.FromStream(ms);
