推荐答案

这是获得单元格值的方法： http：// msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.value.aspx [ ^ ]。



如果你不是确保if的类型是正确的类型（ System.Windows.Forms.DataGridViewImageCell 还是能够在值中存储图像的自定义类型，您可以检查该值是否具有您期望的类型：

http://msdn.microsoft.com/en- us / library / system.windows.forms.datagridviewcell.valuetype.aspx [ ^ ]。



关于在数据库中存储和检索图像老实说，一遍又一遍地回答这个问题并不好。您可以从现有答案中找到所有答案： http://www.codeproject.com/search.aspx?doctypeid=5&q=database+%28image+OR+images+OR+bitmap+OR+bitmaps%29 [ ^ ]。

This is how you get a value of the cell: http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.value.aspx[^].

If you are not sure that the cell of if the proper type (System.Windows.Forms.DataGridViewImageCell or a custom type capable of storing an image in its Value, you can check up that the value has the type you expect:
http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.valuetype.aspx[^].

As to the storing and retrieving images in/from a database, honestly, it''s not good to answer this question over and over. You can find it all from existing answers: http://www.codeproject.com/search.aspx?doctypeid=5&q=database+%28image+OR+images+OR+bitmap+OR+bitmaps%29[^].

Good luck,
