是否有任何黑客方法可以访问声明为内部的父属性？

Question

The problem is I have AspxGridView with Bands and Columns. I need to add Bands (class GridViewBands ) with ColRowSpan = 2 , but this property exists only in parent class - GridViewColumn . GridViewColumn has property ColRowSpan , but it is declared as "protected internal". Also, I tried to access it during debug - it works! But in the code I got exception.

Please, let me know does any method exist to access and change this property?

I found the solution. It needs to use Reflection in this case. The code will be like this:<b

var gridViewColumnType = typeof(GridViewColumn);
var cellRowSpanProperty = gridViewColumnType.GetProperty("CellRowSpan", BindingFlags.Instance | BindingFlags.NonPublic);
cellRowSpanProperty.SetValue(bandcolumn, 2);
