How would I search a range of ranged values using C#

Question

I have a list of values like this

1000, 20400
22200, 24444

The ranges don\'t overlap.

What I want to do is have a c# function that can

Is this functionally what you're after? If so, and you just want it to be more performant, than change the foreach in the ValueRangeCollection to a binary search..

    public struct ValueRange 
    { 
       public int LowVal; 
       public int HiVal; 
       public bool Contains (int CandidateValue) 
       { return CandidateValue >= LowVal && CandidateValue <= HiVal; } 
       public ValueRange(int loVal, int hiVal)
       {
          LowVal = loVal;
          HiVal = hiVal;
       }
   }

    public class ValueRangeCollection: SortedList 
    { 
        public bool Contains(int candValue) 
        {  
            foreach ( ValueRange valRng in Values)
                if (valRng.Contains(candValue)) return true;
            return false; 
        }
        public void Add(int loValue, int hiValue)
        {
            Add(loValue, new ValueRange(loValue, hiValue));
        }
    }
