我不认为该框架中内置了任何功能，即使
Array.Copy在这种情况下也无法实现。但是，通过循环编写代码很容易：
using System;using System.Collections.Generic;class Test{ static void Main() { List<int[]> list = new List<int[]> { new[] { 1, 2, 3 }, new[] { 4, 5, 6 }, }; int[,] array = CreateRectangularArray(list); foreach (int x in array) { Console.WriteLine(x); // 1, 2, 3, 4, 5, 6 } Console.WriteLine(array[1, 2]); // 6 } static T[,] CreateRectangularArray<T>(IList<T[]> arrays) { // TODO: Validation and special-casing for arrays.Count == 0 int minorLength = arrays[0].Length; T[,] ret = new T[arrays.Count, minorLength]; for (int i = 0; i < arrays.Count; i++) { var array = arrays[i]; if (array.Length != minorLength) { throw new ArgumentException ("All arrays must be the same length"); } for (int j = 0; j < minorLength; j++) { ret[i, j] = array[j]; } } return ret; }}
