Methods

GetEnumerator(Range)

Allows the ability to use a for loop to iterate over the indices of a . The indices of the range are the inclusive lower and upper bounds of the enumeration.

Declaration

public static RangeEnumerator GetEnumerator(this Range range)

Parameters

Type	Name	Description
Range	range	The range whose indices over which will be enumerated.

Returns

Type	Description
RangeEnumerator	A RangeEnumerator that will enumerate over the indices of range.

Remarks

This method aims to implement Python-esque for loops in C# by taking advantage of the language syntax used to define a value. Negative bounds may be specified using the C# ^ operator, or by providing an whose property is true.

Examples

The following example counts from 0 to 10 inclusive:

    foreach (var i in 0..10)
    {
        Console.WriteLine(i);
    }

To use negative bounds, use the ^ operator. The following example counts from -5 to 5 inclusive:

    foreach (var i in ^5..5)
    {
        Console.WriteLine(i);
    }

Decrementing enumeration is supported. The following example counts from 5 to -5 inclusive:

    foreach (var i in 5..^5)
    {
        Console.WriteLine(i);
    }
