img数据库

⑴ 数据库以img存储，如何读取图片

直接使用企业管理器好像没有办法操作吧，通过软件或自己做个小软件读取。

#region //读取数据库中图片到内存.并显示
public void LoadToMemoryAndDisable(string serverAdress, string database)
{
//读取数据库中图片到内存.并显示
SqlConnection conn = new SqlConnection("server=" + serverAdress + ";integrated security = sspi;database = " + database);
SqlCommand cmd = new SqlCommand("select * from imgtable where imgname like '%bmp%'", conn);
conn.Open();
SqlDataReader dr;
try
{
dr = cmd.ExecuteReader();
dr.Read();
System.Data.SqlTypes.SqlBinary sb = dr.GetSqlBinary(2);
//或byte[] imageData = (byte[])dr[2];
MemoryStream ms = new MemoryStream(sb.Value);//在内存中操作图片数据
Bitmap bmp = new Bitmap(Bitmap.FromStream(ms));
this.pictureBox1.Image = bmp;
dr.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
conn.Close();
}
}
