使用Humanizer或Regex在每个/周围添加空间

我有一个像这样的字符串:

var text = @"Some text/othertext/ yet more text /last of the text";

我想规范每个斜杠周围的空格，使其匹配以下内容:

var text = @"Some text / othertext / yet more text / last of the text";

也就是说，每个斜杠前和斜杠后各有一个空格。我怎么能做到这一点使用Humanizer或，除非，与单个正则表达式?Humanizer是首选解决方案。

我可以使用以下对正则表达式来实现:

var regexLeft = new Regex(@"'S/");    // 'S matches non-whitespace
var regexRight = new Regex(@"/'S");
var newVal = regexLeft.Replace(text, m => m.Value[0] + " /");
newVal = regexRight.Replace(newVal, m => "/ " + m.Value[1]);

  var text = @"Some text/othertext/ yet more text /last of the text";
  // Some text / othertext / yet more text / last of the text 
  string result = Regex.Replace(text, @"'s*/'s*", " / ");
