i guess this is what would solve this problem.

Code:
            
//Set LowestNumber to the maximum value
int LowestNumber = int.MaxValue;

//Create a list you can fill with int values
List<int> MyIntList = new List<int>();

//Add some values
MyIntList.Add(43);
MyIntList.Add(21);
MyIntList.Add(6);
MyIntList.Add(102);
MyIntList.Add(93);
...
