在 C# 中使用 LINQ 将分隔字符串转换为数组和组

Question

我有一个带有分隔格式的字符串，如下所示：

组织名：名姓氏，名姓姓氏；

（这可以与组织名称和每个组织的可变名称重复）

例子：

**XXX University**: Martha Zander, Rick Anderson; **Albert School**: Nancy Vanderburg, Eric Towson, George Branson; **Hallowed Halls**: Jane Goodall, Ann Crabtree, Rick Grey, Tammy Hudson;

生成的字符串需要按 orgname 和 lastname 进行分组和排序，如下所示：

**Albert School**: George Branson, Eric Towson, Nancy Vanderburg; 
**Hallowed Halls**: Ann Crabtree, Jane Goodall, Rick Grey, Tammy Hudson;
**XXX University**: Rick Anderson, Martha Zander;

我已经走到这一步了：

string[][] splitThis = staff.Split(';').Select(s => s.Split(':')).ToArray();

这给了我一个按 orgname 拆分的数组，然后我被卡住了。

我知道我需要一个包含 orname、firstname、lastname 的多维数组，但我不知道如何填充、分组和排序以获得正确的结果。

Answer 1

public static void Main()
{
    var input =
    @"**Albert School**: George Branson, Eric Towson, Nancy Vanderburg; 
     **Hallowed Halls**: Ann Crabtree, Jane Goodall, Rick Grey, Tammy Hudson;
     **XXX University**: Rick Anderson, Martha Zander;";

    var universities = input
                      .Split(';')
                      .Select(ParseUniversity)
                      .ToArray();
}

public static University ParseUniversity(string line)
{
    var fields = line
                .Split(',',':')
                .Select(f=>f.Trim('*','\n','\r', '\t' ,' '))  // remove trailing crap
                .ToArray();

    var universityName = fields.First();

    var persons = fields
                 .Skip(1)  // skip university field
                 .Select(ParsePerson)
                 .ToArray();

    return new University {Name = universityName, Persons = persons};
}

public static Person ParsePerson(string field)
{
    var p = field.Split(' ');
    return new Person{FirstName = p.First(), LastName = p.Last()};
}

public class University
{
    public string   Name    {get;set;}
    public Person[] Persons {get;set;}
}

public class Person
{
    public string FirstName {get;set;}
    public string LastName  {get;set;}
}

Answer 2

我会在这里使用正则表达式

string input = @"**XXX University**: Martha Zander, Rick Anderson; **Albert School**: Nancy Vanderburg, Eric Towson, George Branson; **Hallowed Halls**: Jane Goodall, Ann Crabtree, Rick Grey, Tammy Hudson;";
var dict = Regex.Matches(input, @"\*\*(.+?)\*\*: (.+?);")
           .Cast<Match>()
           .ToDictionary(x => x.Groups[1].Value, x=>x.Groups[2].Value.Split(','));

dict 将是（在 json 中）：

{
  "XXX University": [
    "Martha Zander",
    " Rick Anderson"
  ],
  "Albert School": [
    "Nancy Vanderburg",
    " Eric Towson",
    " George Branson"
  ],
  "Hallowed Halls": [
    "Jane Goodall",
    " Ann Crabtree",
    " Rick Grey",
    " Tammy Hudson"
  ]
}
