是"在WPF的文本框中加载文件，而不是显示文件内容，计算后在文本框中显示  特殊字符的数量。并将此结果保存在< g class =" gr_ gr_160 gr-alert gr_gramm gr_inline_cards
gr_run_anim Grammar only-ins doubleReplace replaceWithoutSep"数据-GR-ID =" 160" ID = QUOT; 160">文字< / g取代;文件。结果必须如下所示 "

推荐答案

这是尝试的东西，用读取的信息替换项目var来自文本文件。

Here is something to try, replace items var with information read in from the text file.

string items = "ÝABCÓDE?ÃFGHÃI?YJKLÓƒƒMÆNOPRSŠTU??VZݽ¥¥¥¥";

Encoding iso = Encoding.GetEncoding("ISO-8859-1");
Encoding utf8 = Encoding.UTF7;
byte[] utfBytes = utf8.GetBytes(items);
byte[] isoBytes = Encoding.Convert(utf8, iso, utfBytes);
string itemsTranslated = iso.GetString(isoBytes);

var characterGroup = (
    from chr in itemsTranslated.ToCharArray()
    group chr by chr into grp
    select new
    {
        Letter = grp.Key,
        Occurrences = grp.Count(),
        Code = Convert.ToInt32((int)grp.Key)
    })
    .ToList()
    .OrderBy((item) => item.Letter.ToString());

var results = (from item in characterGroup select item);


foreach (var item in results)
{
    Console.WriteLine(

" {item.Letter} ，{item.Code}，{item.Occurrences}"）;
}

"{item.Letter}, {item.Code}, {item.Occurrences}"); }
