使用字符顯示一個字

Question

新的C＃，我必須爲以下編寫一個控制檯應用程序。

用戶可以輸入他的話，言獲取存儲到一個數組，

用戶被提示輸入一個字符，字符將檢索所有具有該字符的話。我不知道如何在if語句中設置條件，以及如何使用userinput來檢索單詞。這是我嘗試代碼：

int WCount; 
string LargestWord = " "; 
string SmallestWord = " "; 
int vowelcount = 0; 

List<string> wordsarr = new List<string>(); 
Console.WriteLine("How many words are you going to enter?"); 
WCount = int.Parse(Console.ReadLine()); 

for (int j = 0; j < WCount; j++) 
{ 
    Console.WriteLine("Please enter your word"); 
    wordsarr.Add(Console.ReadLine()); 
    LargestWord = wordsarr[0]; 
    SmallestWord = wordsarr[1]; 
    string vowel = wordsarr[j].ToString(); 

    if(LargestWord.Length<wordsarr[j].Length) 
    { 
    LargestWord = wordsarr[j]; 
    } 
    else if (SmallestWord.Length>wordsarr[j].Length) 
    { 
    SmallestWord = wordsarr[j]; 
         } 
    Console.WriteLine("Please enter a letter: "); 
    char userinput = char.Parse(Console.ReadLine()); 

    if (userinput == wordsarr[j]) 
    { 

    } 
    } 

Answer 1

我會做這樣的事情：

Console.WriteLine("How many words are you going to enter?"); 
int wordCount = int.Parse(Console.ReadLine()); 

string[] words = new string[wordCount]; 
for (int i = 0; i < words.Length; i++) 
{ 
    Console.WriteLine("Please enter your word"); 
    words[i] = Console.ReadLine(); 
} 

Console.WriteLine("Please enter a letter: "); 
string searchChar = Console.ReadLine(); 

for (int i = 0; i < words.Length; i++) 
{ 
    string word = words[i]; 
    if (word.Contains(searchChar) == true) 
    { 
    Console.WriteLine(word); 
    } 
}

您可以使用方法找到wordsarr調用像 wordsarr.Find() Plsease檢查如何使用在這裏找到方法http://www.codeproject.com/Articles/388257/Csharp-Tips-Using-delegate-in-List-Find-predicate 要檢查是否字符串包含給定字符看這裏How can I check if a string contains a character in C#?
