Range(int, int, int)

Generates a sequence of integral numbers within a specified range.

Declaration

public static IEnumerable<int> Range(int start, int count, int step)

Parameters

Type	Name	Description
int	start	The value of the first integer in the sequence.
int	count	The number of sequential integers to generate.
int	step	The step increment for each returned value.

Returns

Type	Description
IEnumerable<int>	An IEnumerable<T>that contains a range of sequential integral numbers.

Remarks

This operator uses deferred execution and streams its results.

Examples

The following code example demonstrates how to generate a sequence of values using Range.

// Generate a sequence using a sequence function
var result = SuperEnumerable
    .Range(1, 10, 2);

Console.WriteLine(
    "[" +
    string.Join(", ", result) +
    "]");

// This code produces the following output:
// [1, 3, 5, 7, 9, 11, 13, 15, 17, 19]

Exceptions

Type	Condition
ArgumentOutOfRangeException	count is less than 0. -or- start + (count -1) * step cannot be contained by an int.
