The last solution will help you here.

没有标准功能可以执行:您可能可以在Linq中执行此操作，但是此组合也可以使用:

There is no standard function that will do it: you can probably do it in Linq, but this combo also works:

private static char FindMostFrequent(string input)
    {
    char[] distinct = input.Distinct().ToArray();
    int max = -1;
    char most = input[0];
    foreach (char d in distinct)
        {
        int count = input.Count(c => c == d);
        if (count > max)
            {
            max = count;
            most = d;
            }
        }
    return most;
    }
