c# - 复制 DataGridViewColumnHeaderCell obj

Question

我不认为 DataGridViewColumnHeaderCell 实现了 IClonable 所以我正在考虑使用 Xml.Serialization 来复制这个对象以避免不必要的引用。你怎么看？矫枉过正？

Answer 1

You haven't to do it, DataGridViewColumnHeaderCell implements the IClonable.Clone() method.

object clonedObject = myDataGridViewColumnHeaderCell.Clone();

EDIT:

but it doesn't copy the data. And ColumnIndex is a readonly property which is one of 2 properties I'm interested in preserving.

Sincerly I've never used it on DataGridViewColumnHeaderCell, but it should work. Howerever If you just need to preserve two properties you can create your customized Clone method:

public static class Utilities{
    public static object CloneObject(this DataGridViewColumnHeaderCell myObj){
         DataGridViewColumnHeaderCell clonedObject = new DataGridViewColumnHeaderCell();

         //here clone your properties
         clonedObject.ColumnIndex = myObj.ColumnIndex;              

         return clonedObject;
    }
}

Then:

object clonedObject = myDataGridViewColumnHeaderCell.CloneObject();

PS: In the case of ColumnIndex you just need to assign it to the new object because it's of type int which is a struct and you don't pass a reference.

Answer 2

我对此进行了测试，克隆从未出于某种未知原因复制该对象。我不得不复制每一行的属性。
