Question

如果第一个字段相同，我很难在逗号分隔的文本文件中组合一些行。这是我的档案：

Area 1 Chiller Grids aB aN and a1 a6,test,1,Ground Floor Framing
Area 1 Chiller Grids aB aN and a1 a6,test,2,Monorails West
Area 1 Chiller Grids aB aN and a1 a6,test,6,Roof Framing West
Area 1 Chiller Grids aB aN and a1 a6,test,11,Bullnose West
Area 2 Office Grids aN zA and a1 a6,101806,3,First Floor Framing East
Area 2 Office Grids aN zA and a1 a6,101806,5,Mezz Floor Framing
Area 2 Office Grids aN zA and a1 a6,101806,7,Roof Framing East
Area 2 Office Grids aN zA and a1 a6,101806,9,First Floor Ceiling
Area 3 Bridge Grids yA yE and a1 10x,101807,4,Link Floor Framing
Area 3 Bridge Grids yA yE and a1 10x,101807,8,Link Roof Framing
Area 3 Bridge Grids yA yE and a1 10x,101807,10,Bridge Catwalks
Area 3 Bridge Grids yA yE and a1 10x,101807,13,Stair 1

我需要输出为：

Area 1 Chiller Grids aB aN and a1 a6,test,1-2-6-11,Ground Floor Framing-Monorails West-Roof Framing West-Bullnose West
Area 2 Office Grids aN zA and a1 a6,101806,3-5-7-9,First Floor Framing East-Mezz Floor Framing-Roof Framing East-First Floor Ceiling
Area 3 Bridge Grids yA yE and a1 10x,101807,4-8-10-13,Link Floor Framing-Link Roof Framing-Bridge Catwalks-Stair 1

我该如何解决这个问题？我已经尝试了一些我在这里找到的linq代码，但它并没有得到我想要的东西，我不知道该怎么做：

                var a = System.IO.File.ReadAllLines(@"X:\Steelcad_Project_Files\" + dir + "\\manager1.txt");
                var b = System.IO.File.ReadAllLines(@"X:\Steelcad_Project_Files\" + dir + "\\manager.txt");

                var query =
                    from bline in b
                    let parts = bline.Split(',')
                    group parts[2] by parts[0] into bg
                    join aline in a on bg.Key equals aline
                    select aline + "," + string.Join("-", bg.ToArray());

                System.IO.File.WriteAllLines(@"X:\Steelcad_Project_Files\" + dir + "\\result.txt", query.ToArray());

其中manager1文件中只包含第一个字段，如下所示：

Area 1 Chiller Grids aB aN and a1 a6
Area 2 Office Grids aN zA and a1 a6
Area 3 Bridge Grids yA yE and a1 10x

如果可能的话，我想只使用1个文件。任何帮助将非常感激。感谢

编辑：是否可以根据第0行和第2行对行进行排序？如果它是1-11-15-2-6可以重新排列到1-2-6-11-15但是将所有区域1保持在一起等吗？

Answer 1

var output = File.ReadAllLines(@"D:\\manager.txt")
    .Select(line => line.Split(','))
    .GroupBy(line => line[0] + "," + line[1])
    .Select(group =>
         group.Key + "," + 
         String.Join("-", group.Select(line => line[2]).ToArray()) + "," +
         String.Join("-", group.Select(line => line[3]).ToArray())
    );

Answer 2

试试这个

var results = from l in File.ReadAllLines(@"..\..\TextFile1.txt")
              let fields = l.Split(new[] { ',' })
              group fields by fields[0] into g
              select (g.Key + "," +
              String.Join("-", g.Select(l => l[2]).ToArray()) +
              "," +
              String.Join("-", g.Select(l => l[3]).ToArray()));

合并文本文件行c＃
