Question

if i have multiple values for same key then how to add it in hash table
for example:

                   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";

this is taking only last group in hashtable i.e

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

how to solve this….thanks in advance!!

Answer 1

A hashtable is defined as having unique keys, and the indexer replaces existing values. It sounds like you actually want a list of objects, i.e.

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 = "..." }
};

with

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