Find the name of the student with the top mark, display their name and mark

+4
−9

I have a CSV file like this:

name,surname,score
Moon,Walko,148
Jerald,Gryder,150

I need to find the highest score. My attempt:

namespace test
{ 
    class Program 
    { 
        string[] Data; 
        static void Main(string[] args) 
        { 
            ReadIn(); 
        }

        public static void ReadIn() 
        { 
            StreamReader Reader = new StreamReader("TestData.csv");
            string datafile = Reader.ReadToEnd(); 
            char[] Seperators = new char[] { ' ', ',', '.' }; 
            string[] Data = datafile.Split(Seperators); 
            for (int i = 0; i < Data.Length; i++ ) 
            {
                Console.WriteLine(Data[i]); 
            } 
            Console.Read(); 
        } 
    } 
}

Read the csv file line-wise. The StreamReader has a method for doing that. That will make it easier to iterate over the records/lines. Then you could just use a variable that keeps track of the currently maximum score value when iterating through the records. If a record has a score that is greater than the current maximum score value variable, assign that value to that variable (or you could use some Linq expression on a collection of records).
