请问在C#中如何向数据库插入图片?
如题!数据库就用sql2005!!在数据库中图片的存储形式好像是以二进制的形式存储的,存进去后,看不出图的样子?现在我想例如在.NET中,用一个控件把一个图片存进数据库,然后在用另一个控件再把图片读出来显示! 
 请问该怎么做?是不是要用到特殊控件??

 		SqlCommand cmd = new SqlCommand( "INSERT INTO Categories(CategoryName, Picture) VALUES (@CategoryName, @Picture) ", cn);   
 		cmd.Parameters.Add( "@CategoryName ", SqlDbType.NVarChar, 15).Value = categoryName; 
 		cmd.Parameters.Add( "@Picture ", SqlDbType.Image, photo.Length).Value = photo;   
 		cn.Open(); 
 		cmd.ExecuteNonQuery(); 
 		cn.Close();
