C# 根据英文首字母排序

代码：

List<string> list = new List<string>() { "Ace", "Abbiy", "Jack", "Rose", "Micheal", "Milk", "Lucy", "Peach", "Jimmy" };
Dictionary<string, dynamic> dict = new Dictionary<string, dynamic>();
List<IGrouping<string, string>> data = list.OrderBy(p => p.Substring(0, 1)).GroupBy(p => p.Substring(0, 1)).ToList();

foreach (var item in data)
 {
      dict.Add(item.Key, item.Select(p => new {  Name = p }));
 }
Console.WriteLine(JsonConvert.SerializeObject(dict));

结果：

{
    "A":[
        {
            "Name":"Ace"
        },
        {
            "Name":"Abbiy"
        }
    ],
    "J":[
        {
            "Name":"Jack"
        },
        {
            "Name":"Jimmy"
        }
    ],
    "L":[
        {
            "Name":"Lucy"
        }
    ],
    "M":[
        {
            "Name":"Micheal"
        },
        {
            "Name":"Milk"
        }
    ],
    "P":[
        {
            "Name":"Peach"
        }
    ],
    "R":[
        {
            "Name":"Rose"
        }
    ]
}
