You can easily make one from a dictionary of lists:

public class MultiValueDictionary : Dictionary> {

  public void Add(Key key, Value value) {
    List values;
    if (!this.TryGetValue(key, out values)) {
      values = new List();
      this.Add(key, values);
    }
    values.Add(value);
  }

}
