推荐答案

请查看MSDN帮助页面上的System.Windows.Forms.DataGridViewCell. Value的类型是什么?是的，它是System.Object.这意味着:您几乎可以托管任何东西.

请参阅:

Look at the MSDN help page for the System.Windows.Forms.DataGridViewCell. What is the type of its Value? Right, it''s System.Object. It means: you can host nearly anything.

Please see:

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