Edit: I originally misunderstood the problem to be looking for the character that occurred most frequently (i.e. the "mode" of the data set). Actually, the OP wants to know how many times the mode is repeated in the data set.
static int CountMode<T>(IEnumerable<T> str)
{
return str.GroupBy(c => c).Select(g => g.Count())
.OrderBy(freq=>freq).LastOrDefault();
}
Note the similarity to mjolka's LINQ solution mjolka's LINQ solution. This differs in how the empty string case is handled (since there is no MaxOrDefault()). The ternary version is shorter; however, the LINQ version can work for all IEnumerable<T> without multiple enumeration.
