C# - 如何找到最低和最高数字之间的差异

Question

I have a List that contains multiple numbers like this:

• 1.75
• 1.25
• 2.03
• 1.44

What I want to do, is to find a difference between lowest and highest number. In this case it would be 1.25 and 2.03 , which would make 0.78 .

How should I do it?

Answer 1

The steps are quite simple:

1. Find the largest number in the list
2. Find the smallest number in the list
3. The result you need = [Result of 1] - [Result of 2]

To implement this you can use LINQ:

// Intialize your list (or use the existing one)
var list = new List<decimal>{ 1.75m, 1.25m, 2.03m, 1.44m};
// The result is maximum of the list minus minimum of the list
var result = list.Max() - list.Min();
// Print or use the result
Console.WriteLine(result);  // prints the result 0.78

Answer 2

首先确定最大值和最小值，然后从最大值中减去最小值。

Answer 3

There are a few different ways you can do it, but first a few questions:

1. Is the list sorted? If it is, then it's really simple.
2. If it's not sorted, then you may iterate through the list, an have two variables "min" and "max", and in the end just find the difference.
3. Are you given the list? If not and you are the one adding values to the list, then you can keep track of the added values, and assign them appropriately to your "min" and "max" variables.
4. You can use LINQ
