c# - 单键具有不同值的哈希表

Question

如果我对同一个键有多个值，那么如何将它添加到哈希表中 例如:

                   Hashtable hs = new Hashtable();
                      hs["id"]= "x001.xhtml";
                      hs["media-type"]= "application/xhtm+xml"; 
                      hs["href"]= "text/001.xhtml";

                      hs["id"]= "x002.xhtml";
                      hs["media-type"]= "application/xhtm+xml";
                      hs["href"]= "text/002.xhtml";

                     hs["id"]= "x003.xhtml";
                     hs["media-type"]= "application/xhtm+xml";
                     hs["href"]= "text/003.xhtml";

这只取哈希表中的最后一组，即

                     hs["id"]= "x003.xhtml";
                     hs["media-type"]= "application/xhtm+xml";
                     hs["href"]= "text/003.xhtml";

如何解决这个问题....提前致谢!!

哈希表被定义为具有唯一键，索引器替换现有值。听起来您实际上想要一个对象列表，即

var list = new List<YourType> {
    new YourType { Id = "x001.xhtml", MediaType = "...", Href = "..." },
    new YourType { Id = "x002.xhtml", MediaType = "...", Href = "..." },
    new YourType { Id = "x003.xhtml", MediaType = "...", Href = "..." }
};

与

public class YourType {
    public string Id {get;set;}
    public string MediaType {get;set;}
    public string Href {get;set;}
}

(或类似的)
