c# - 使用 linq 将字符串转换为 3D 数组

Question

我看到了例子，并实现了 linq 来将定界字符串转换为二维数组，如下所示:

using System;
using System.Linq;

namespace AACOBusinessModel.Extensions
{
  [Serializable]
  public class TwoDimensionalStringArray
  {
    public TwoDimensionalStringArray(string data)
    {
      // 1;2;3^^4;5;6
      this.Data = (
          from string line
          in data.Split(new string[] { "^^" }, StringSplitOptions.RemoveEmptyEntries)
          select line.Split(';')
        ).ToArray();
    }

    public TwoDimensionalStringArray() { }

    public readonly string[][] Data = { };

    public override string ToString()
    {
      return string.Join("^^",
        from string[] line
        in Data
        select string.Join(";", line)
      );
    }
  }
}

当我尝试以 3D 形式制作此作品时，我遇到了一个问题:

using System;
using System.Linq;

namespace AACOBusinessModel.Extensions
{
  [Serializable]
  public class ThreeDimensionalStringArray
  {
    public ThreeDimensionalStringArray(string data)
    {
      // 1;2;3^^4;5;6@4;4;4^^7;7;7
      this.Data = (
          from string line2D
          in data.Split(new string[] { "@" }, StringSplitOptions.RemoveEmptyEntries)
          from string line
          in line2D.Split(new string[] { "^^" }, StringSplitOptions.RemoveEmptyEntries)
          select line.Split(';')
        );
    }

    public ThreeDimensionalStringArray() { }

    public readonly string[][][] Data = { };

    public override string ToString()
    {
      return string.Join("@",
        from string[][] line2D
        in Data
        select string.Join("^^", 
          from string[] line 
          in line2D
          select string.Join(";", line)
        )
      );
    }
  }
}

我知道对于 2D，结束选择是转换为数组的拆分集合，从而形成一个 2D 数组。

但是对于 3D，结束选择需要选择二维数组的集合。我不知道该怎么做。

更新

我想到了这个，但如果可能的话，我想要查询语法。

public ThreeDimensionalStringArray(string data)
{
  this.Data = (
      from string line2D
      in data.Split(new string[] { "@" }, StringSplitOptions.RemoveEmptyEntries)
      select (
        from string line
        in line2D.Split(new string[] { "^^" }, StringSplitOptions.RemoveEmptyEntries)
        select line.Split(';')
      ).ToArray()
    ).ToArray();
}

Answer 1

不确定在查询语法中应该如何完成，但这里是方法语法版本:

this.Data = data
    .Split(new[] { "@" }, StringSplitOptions.RemoveEmptyEntries)
    .Select(table => table.Split(new[] { "^^" }, StringSplitOptions.RemoveEmptyEntries)
        .Select(row => row.Split(';'))
        .ToArray())
    .ToArray();

在查询语法中:

this.Data = (
    from table in data.Split(new[] { "@" }, StringSplitOptions.RemoveEmptyEntries)
    select
    (
        from row in table.Split(new[] { "^^" }, StringSplitOptions.RemoveEmptyEntries)
        select row.Split(';')
    ).ToArray()
).ToArray();
