Regex提取“；从“；来自邮件档案，包括名称和换行符

match = Regex.Match(msg, @"(?<=From:)", RegexOptions.Multiline | RegexOptions.IgnoreCase | RegexOptions.IgnorePatternWhitespace);

我也试过下面的表达式，但它把其他记录搞砸了。

match = Regex.Match(msg, @"(?<=From:).*.'s*.*'s*(>)", RegexOptions.Multiline | RegexOptions.IgnoreCase | RegexOptions.IgnorePatternWhitespace);

我想做以下事情
-抓取以From:开头的行，但不要捕获它，即（？<=From:）
-现在继续，直到您到达">"，它必须包括空格、换行符等所有内容

我很难想出这个表达方式。

我已经完成了匹配换行符的正则表达式，c-sharp-regex-match-any-text-between-tags-included-new-lines，但无法在我的代码中实现它。
