c# - 我怎么知道我可以在 GetRow() 上转换成什么类型​​？

Question

void gridControl1_DoubleClick(object sender, EventArgs e) {
    GridControl grid = sender as GridControl; 
    DXMouseEventArgs args = e as DXMouseEventArgs;
    BaseHitInfo hitInfo = grid.Views[0].CalcHitInfo(args.Location);
    GridHitInfo gridHit = hitInfo as GridHitInfo;
    if (GridHitTest.RowCell == gridHit.HitTest) {
        int rowHandle = gridHit.RowHandle;
        grid.MainView.GetRow(rowHandle);//GetRow returns Object. I need to cast this to a Type to make it useful
    }
}

我有 documentation对于 GetRow()。我无法提取比我已经通过智能感知提取的有用信息多得多的信息。

我怎么知道我可以将其转换到什么？

Answer 1

文档对我来说似乎相当清楚:

This method's return value depends upon the type of the View's data source. If the data source is a System.Data.DataTable or a System.Data.DataView, this method returns a System.Data.DataRowView object. If the data source is a custom list of items, the appropriate list item is returned.

那么您的来源是什么？是DataTable吗/DataView ？如果是这样，转换到DataRowView .如果是 List<T>或类似的东西，然后转换为元素类型。我假设您确实在编译时知道您的数据源类型是什么？
