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" };

我想构建一个指向这些数组的数组：

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

当我将索引放入此（ArrayReferences）数组时，我想获取特定数组的所有元素，如下所示：

string[] _PMDTableColumnNames = ArrayReferences[1];

我该怎么做？

Answer 1

您可以创建一个数组数组：

private string[][] ArrayReferences;

请注意，您必须在构造函数中初始化ArrayReferences，因为您无法引用字段初始化程序中的其他数组。即。

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 };

或只是

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

应该这样做。

Answer 3

您只需使用ArrayList类就可以达到这种目的。
