我如何在 C# 中找到不正確的單詞及其計數？

Question

我喜歡從給定的文本中對不匹配/錯誤的單詞進行排序，例如字符串 s1="let's play Football" s2="let's paly fotbal and cricket"

現在我想要沒有。 String-s2 中的錯誤以及額外的單詞，如paly 和 fotbal、cricket以及類似的這些錯誤單詞的計數。

Answer 1

string s1 = "let's play football";
string s2 = "let's paly fotbal and cricket";

if (s1 != s2)
{
    var str1Parts = s1.Split(' ');
    var str2Parts = s2.Split(' ');

    var wrongOrExtraWords = str2Parts.Where(s => !str1Parts.Contains(s)).ToList();

    Console.WriteLine("Wrong words: ({0})", wrongOrExtraWords.Count());

    foreach (var str2 in wrongOrExtraWords)
    {
        Console.WriteLine(str2);
    }
}
else
{
    Console.WriteLine("Both strings are equal.");
}

Answer 2

        string s1 = "let's play football";
        string s2 = "let's paly fotbal and cricket";

        string[] sArr1 = s1.Split(' ');
        string[] sArr2 = s2.Split(' ');

        int wrongCount = 0;

        for (int i=0; i< sArr1.Length; i++)
        {
            if (sArr1[i] != sArr2[i]) //for different words
                wrongCount++;
        }

        wrongCount +=  sArr2.Length - sArr1.Length; //for extra words

        //wrongCount = 4
