How do you check if a number is within a range?
If x is in range, then it must be greater than or equal to low, i.e., (x-low) >= 0. And must be smaller than or equal to high i.e., (high – x) <= 0. So if result of the multiplication is less than or equal to 0, then x is in range.

3 Answers. The first parameter you pass in the GetRange method is the index it will start the copy and the second parameter the number of elements that will be copied. If index = 5 and count = 7 , it will try to copy the values of the element in the following positions: 5, 6, 7, 8, 9, 10, 11(?)
How do you code a range in C#?
To program a range loop in C# we use the Range() LINQ extension method. That method makes an enumerable ( IEnumerable ) with a range of integer values (Microsoft Docs, n.d. a; Stephens, 2014). We then loop over that enumerable to implement the range loop. To access that method we use the static Enumerable class.
How check value is decimal or not in C#?
