一些解释：您可以假设某些单元格的运行时类型为 System.Windows.Forms .DataGridViewImageCell ;如果你问这个问题，它应该暗示你要注意使用相应的列类型或这个单元格类型用于单独的单元格;并且单元格包含有效的图像数据。您可以检查单元格的 ValueType ，看看它是什么类型的数据： https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.valuetype（v = VS。 110）.aspx [ ^ ]。

Some explanations: you can assume that the runtime type of some cell is System.Windows.Forms.DataGridViewImageCell; if you are asking this question, it should imply that you take care about using corresponding column type or this cell type for a separate cell; and the cell contains valid image data. You can check ValueType for the cell and see what kind of data it is: https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.valuetype(v=vs.110).aspx[^].
