C＃陣列由％

Question

排序我有一個字母排列，像這樣：

10% A 
20% A 
30% A 
40% B 
50% B 
60% B 
70% B 
80% C 
90% C 
100% D 

我需要的代碼給我造成這樣的：

A 10%-30% 
B 40%-70$ 
C 80%-90% 
D 100%-100% 

Answer 1

如果你的數組進行排序那樣，這應爲你工作：

var result = values.GroupBy(x => x.Last()) 
       .Select(
        x => 
         string.Format("{0} {1} - {2}", x.Key.ToString(), 
          x.First().Split()[0], 
          x.Last().Split()[0])); 

Answer 2

從我的角度來看，主題是首發的意思是這樣的：

static void Main() { 
    var array = new[] {"A", "A", "A", "B", "B", "B", "B", "C", "C", "D"}; 
    var result = new Collection<string>(); 

    //as u call it "resolution": 
    const int resolution = 10; 

    var currentSymbol = array[0]; 
    var startIndex = 1; 

    for (var index = 0; index < array.Length; index++) { 
     if (currentSymbol != array[index]) { 
      result.Add(currentSymbol + " " + startIndex*resolution + "%-" +index*resolution); 
      currentSymbol = array[index]; 
      startIndex = index + 1;     
     } 
     if (index + 1 == array.Length) { 
      result.Add(currentSymbol + " " + startIndex * resolution + "%-" + (index + 1) * resolution); 
      currentSymbol = array[index]; 
      startIndex = index + 1;  
     } 
    } 

    foreach (var a in result) { 
     Console.WriteLine(a); 
    } 
    Console.ReadLine(); 
}
