c# - 数组引用数组

Question

我有三个字符串数组：

private readonly string[] PMCTableColumnNames = new string[] { "PMCIP", "Description", "Cam1ReferencePoints", "Cam2ReferencePoints", "DataserverIP" };
private readonly string[] PMDTableColumnNames = new string[] { "PMDIP", "Description" };
private readonly string[] PMDZonesTableColumnNames = new string[] { "PMDIP", "Description", "Zone" };

我想构造一个指向这些数组的数组：

private var[] ArrayReferences = new var[] { PMCTableColumnNames, PMDTableColumnNames, PMDZonesTableColumnNames };

当我将此（ArrayReferences）数组索引时，我想获取特定数组的所有元素，如下所示：

string[] _PMDTableColumnNames = ArrayReferences[1];

我怎样才能做到这一点？

Answer 1

您可以创建一个数组数组：

private string[][] ArrayReferences;

请注意，您必须ArrayReferences在构造函数中进行初始化，因为您无法在字段初始化程序中引用其他数组。IE

public class ClassName
{
    private readonly string[] PMCTableColumnNames = new string[] { "PMCIP", "Description", "Cam1ReferencePoints", "Cam2ReferencePoints", "DataserverIP" };
    private readonly string[] PMDTableColumnNames = new string[] { "PMDIP", "Description" };
    private readonly string[] PMDZonesTableColumnNames = new string[] { "PMDIP", "Description", "Zone" };

    private string[][] ArrayReferences;

    public ClassName()
    {
        ArrayReferences = new string[][] { PMCTableColumnNames, PMDTableColumnNames, PMDZonesTableColumnNames };
    }

    void SomeMethod()
    {
        string[] _PMDTableColumnNames = ArrayReferences[1];
    }
}

Answer 2

string[][] ArrayReferences = new [] { PMCTableColumnNames, PMDTableColumnNames, PMDZonesTableColumnNames };

要不就

var ArrayReferences = new [] { PMCTableColumnNames, PMDTableColumnNames, PMDZonesTableColumnNames };

应该这样做。

您可以简单地使用ArrayList类来实现这种目的。
