问题描述

你好

我有以下内容:

IDictionary<String, IList<String>> data;

推荐答案

以下内容可能会为您解决此问题或给您一些想法:

The following might either solve this for you or give you some ideas:

using System;
using System.Collections.Generic;

namespace MatrixLambda
{
  class Program
  {
    static void Main(string[] args)
    {
      // Load test data.
      IDictionary<String, IDictionary<String, IList<String>>> data = new Dictionary<String, IDictionary<String, IList<String>>>();
      data.Add("A", new Dictionary<String, IList<String>>());
      data["A"].Add("AX", new List<String>());
      data["A"]["AX"] = new string[] { "Hello", "World" };
      data.Add("B", new Dictionary<String, IList<String>>());
      data["B"].Add("BY", new List<String>());
      data["B"]["BY"] = new string[] { "Good", "Evening" };

      // Here is the lambda for the function that determines what goes in each cell given zero-based row and col index.
      Func<int, int, string> f = (row, col) => col == 0 ? data["A"]["AX"][row] : data["B"]["BY"][row];

      String[,] result = new string[2, 2];

      // Apply function to determine what goes in each cell.
      for (int row = 0; row <= result.GetUpperBound(0); row++)
      {
        for (int col = 0; col <= result.GetUpperBound(1); col++)
        {
          result[row, col] = f(row, col);
        }
      }

      // Print for diagnostic.
      for (int row = 0; row <= result.GetUpperBound(0); row++)
      {
        for (int col = 0; col <= result.GetUpperBound(1); col++)
        {
          if (col != 0)
            Console.Write(' ');
          Console.Write(result[row, col]);
        }
        Console.WriteLine();
      }
    }
  }
}
