{
static void Main(string[] args)
{

List<double> lstNumbers = new List<double>() { 1, 2.06, -36.4, -4, 5.90, 61.9, 79.8, 8, 9, 18.0,23.7 };
double minNum = 0;
double maxNum = 0;

minNum = lstNumbers[0];
maxNum = lstNumbers[0];
for(int i = 1;i< lstNumbers.Count;i++)
{
//logic for obtaining the Minimum Number
if (minNum > lstNumbers[i]) minNum = lstNumbers[i];

//logic for obtaining the Maximum Number
if (maxNum < lstNumbers[i]) maxNum = lstNumbers[i];
}
Console.WriteLine("Min = {0} , Max = {1}", minNum, maxNum);
Console.ReadKey(true);
}
}
}


Explanation: First of all we have collected the data and put into a collection.Then we have assumed the first collection element as the Maximum and Minimum number and put in two variables minNum and maxNum. Then we have looped through from second element till the last element in the collection and compared each element with minNum and maxNum variables. If the values found to be greater/smaller, then those values are assigned.
