Is there any easy way to sort NameValueCollection on the basis of key in C#?

I am looking for an easy way to sort NameValueCollection on the basis of key - it should not be a performance heavy though.

From stackoverflow

• Start with SortedDictionary<string,string> or SortedList<string,string> and you're already there...

  If you need the multiple items per key, then consider a SortedDictionary<string,List<string>>. There are ways to simplify addition etc with extension methods - it needn't be scary.

  Note also that NameValueCollection is case-insensitive, so you might need to use one of the insensitive comparisons - for example:

  Dictionary<string,string> data = new Dictionary<string,string>(
              StringComparer.InvariantCultureIgnoreCase);
  

  (edit) here's an example of using an extension method to populate multiple values against a single key in C# 3.0:

      static void Main()
      {
          var data = new Dictionary<string, List<string>>(
              StringComparer.InvariantCultureIgnoreCase);
          data.Add("abc", "def");
          data.Add("abc", "ghi");
      }
  
      static void Add<TKey, TValue>(this IDictionary<TKey, List<TValue>> lookup,
          TKey key, TValue value)
      {
          List<TValue> list;
          if (!lookup.TryGetValue(key, out list))
          {
              list = new List<TValue>();
              lookup.Add(key, list);
          }
          list.Add(value);
      }
  

• Here's a brute force hack that I'm not too proud of, but it works if you need something quick and dirty.

  public static void Sort(this NameValueCollection nameValueCollection)
      {
          // Create a temporary collection the same size as the original
          NameValueCollection tempNameValueCollection = new NameValueCollection(nameValueCollection.Count);
  
          // Sort the keys
          string[] keys = nameValueCollection.AllKeys;
          Array.Sort(keys);
  
          foreach (string key in keys)
          {
              // Sort the values
              string[] values = nameValueCollection[key].Split(',');
              Array.Sort(values);
  
              // Add each value to the temporary collection
              foreach (string value in values)
              {
                  tempNameValueCollection.Add(key, value);
              }
          }
  
          // Clear the original collection
          nameValueCollection.Clear();
  
          // Add the sorted entries back
          nameValueCollection.Add(tempNameValueCollection);
      }
