c# – 将int(或任何值类型)作为对象存储并将它们转换回int(或值

基本上我需要创建一个内存表.我可以创建特定于每种可能类型的“列”(因此任何原始值类型,如int,double,string等,以及我希望存储在表中的用户定义的引用类型,如Order),或者我可以简单地将一切存储为对象并在访问表格时将它们转换回正确的类型.

所以我的问题是哪种方法表现更好或两者都相同？

或者我应该为所有值类型坚持使用特定的“列”并将所有用户定义的引用类型存储为对象？

谢谢 – 下面的示例代码 – 静态测试方法显示用法.

public sealed class Columns
{
    public static void Test()
    {
        Columns cols = new Columns(100);
        cols.SetInt(0,Int_Column,12345);
        int value = cols.GetInt(0,Int_Column);

        cols.SetObject(1,Object_Column,12345);
        int value2 = (int)cols.GetObject(1,Object_Column);
    }

    private const int Int_Column = 0;
    private const int String_Column = 1;
    private const int Object_Column = 2;

    private int[] _intCol;
