推荐答案
首先,您需要保存每个字母的计数。最好的方法是使用Dictionary对象
1st you need to save the count for each alphabet. The best way is to make use of Dictionary object
Dictionary< char,int> countOfLetters = new Dictionary< char,int>();
Dictionary<char, int> countOfLetters = new Dictionary<char, int>();
现在你可以使用foreach循环扫描字符串
Now you can scan the string using a foreach loop
foreach(string coScan中的char c) )
foreach(char c in stringToScan)
在循环内你可以检查字符(字母)是否已经添加
Inside the loop you can check if the character(letter) is already added or not
if(countOfLetters.ContainsKey(c))然后你应该增加点数
if(countOfLetters.ContainsKey(c)) then you should increment the count
countOfLetters [c] ++;
countOfLetters[c]++;
否则你需要将它添加到字数为1的
else you need to add it to the dictionary with count 1
countOfLetters.Add(c,1);
countOfLetters.Add(c, 1);
现在你可以使用另一个foreach循环打印结果
Now you can print the result using another foreach loop
foreach( charc in countOfLetters.Keys)
foreach(char c in countOfLetters.Keys)
Console.WriterLine(" Letter" + c +"出现" + countOfLetter [c] .ToString()+" times。" ;);
Console.WriterLine("Letter " + c + " appeared " + countOfLetter[c].ToString() + " times.");
希望这会有所帮助!!!
