我应该在数据库的URL中存储空格吗？如果是这样，当将它们放入时如何编码？

/

var path = \"/tags/ASP.NET MVC\";
var url = HttpUtility.UrlPathEncode(path).Replace(\"%2f\", \"/\");

private static string EncodeTitleInternal(string title)
{
        if (string.IsNullOrEmpty(title))
                return title;

        // Search engine friendly slug routine with help from http://www.intrepidstudios.com/blog/2009/2/10/function-to-generate-a-url-friendly-string.aspx

        // remove invalid characters
        title = Regex.Replace(title, @\"[^\\w\\d\\s-]\", \"\");  // this is unicode safe, but may need to revert back to \'a-zA-Z0-9\', need to check spec

        // convert multiple spaces/hyphens into one space       
        title = Regex.Replace(title, @\"[\\s-]+\", \" \").Trim(); 

        // If it\'s over 30 chars, take the first 30.
        title = title.Substring(0, title.Length <= 75 ? title.Length : 75).Trim(); 

        // hyphenate spaces
        title = Regex.Replace(title, @\"\\s\", \"-\");

        return title;
}
