C # Gets the maximum, minimum, and average values in an array

C # Gets the maximum, minimum, and average values in an array of 1. Give an array

1             int New int 1,2,4,3,0,-1,545,2 ;

2. Array of arrays self-band method

itself is directly able to call Min (), Max (), Average () method to find the minimum, maximum, and average values

1             Console.WriteLine ("--------------Array own method-----------------"); 2             Console.WriteLine ("min:{0}", array. Min ()); 3             Console.WriteLine ("max:{0}", array. Max ()); 4             Console.WriteLine ("average:{0}", array. Average ());

Output Result:

1 --------------array Self method-----------------2 min:-13 Max:5454 Average:62.4

Output results

The above code is also extracted from the. NET Framework, in fact, the array's own maximum, minimum, average value of the algorithm is done, in the. NET Framework source code can be seen
