c#怎麽把二進制數據轉換為圖片

參考下面的代碼：

public void GetImage()

{

SqlCommand cmd = new SqlCommand(@"SELECT name, photo FROM Temp", sqlConn);

sqlConn.Open();

SqlDataReader reader = cmd .ExecuteReader();

if (reader.Read())

{

image_filename= (string) reader.GetValue(0);

byte[] image_bytes = (byte[]) reader.GetValue(1);

MemoryStream ms = new MemoryStream(image_bytes);

Bitmap bmap = new Bitmap(ms);

return bmap;

}
