C# System.Array 如何计算或查找它有多少维度？

Question

如果我有一个未知数组作为 System.Array，我如何才能找到它有多少维度？我在想一些可以称为 Array.GetDimensionCount() 的东西

例如，如果我在 System.Array 类上构建扩展方法并且我想验证 arrayDimensionIndex 不大于或等于数组的维数，我想抛出 ArgumentOutOfRangeException

    /// <summary>
    /// Determines whether the value of the specified arrayIndex is within 
    /// the bounds of this instance for the specified dimension.
    /// </summary>
    /// <param name="instance">The instance of the array to check.</param>
    /// <param name="arrayDimensionIndex">Index of the array dimension.</param>
    /// <param name="arrayIndex">The arrayIndex.</param>
    /// <returns></returns>
    /// <exception cref="System.ArgumentOutOfRangeException">
    /// If arrayDimensionIndex exceeds the number of dimesnions in the array.
    /// </exception>
    public static bool IsInBounds(this Array instance, int arrayDimensionIndex, int arrayIndex)
    {
        // Determine if this instance has more dimension than the specified array dimension to check.
        if(instance.Get?????() <= arrayDimensionIndex)
        {
            throw new ArgumentOutOfRangeException();
        }

        // Get the length of the dimension specifed
        int arraDimensionLength = instance.GetLength(arrayDimensionIndex);

        // Check if the value is withing the array bounds
        bool isInBounds = ((uint)arrayIndex < arraDimensionLength);

        // Return the result
        return isInBounds;
    }

谢谢。

您要查找的关键词是Rank .使用 Rank 属性找出数组的维数。
