当IsHTML=True时从outlook2016编码的HTML中获取BodytPart中的文本

MimeKit.Text 命名空间。

您可以使用它来删除html标记并只保留字符数据。

using (var writer = new StringWriter ()) {
    using (var reader = new StringReader (html)) {
        var tokenizer = new HtmlTokenizer (reader) {
            DecodeCharacterReferences = true
        };
        HtmlToken token;

        while (tokenizer.ReadNextToken (out token)) {
            switch (token.Kind) {
            case HtmlTokenKind.Data:
                var data = (HtmlDataToken) token;
                writer.Write (data.Data);
                break;
            case HtmlTokenKind.Tag:
                var tag = (HtmlTagToken) token;
                switch (tag.Id) {
                case HtmlTagId.Br:
                    writer.Write (Environment.NewLine);
                    break;
                case HtmlTagId.P:
                    if (tag.IsEndTag || tag.IsEmptyElement)
                        writer.Write (Environment.NewLine);
                    break;
                }
                break;
            }
        }
    }

    return writer.ToString ();
}
