IndexRange 1.1.0

About

This package lets you use the C# 8.0 index and range features in projects that target .NET Framework.

For projects that target netstandard2.0 or .NET Framework 4.6.2 or later, use the Microsoft.Bcl.Memory package instead. This package should be considered deprecated for those target frameworks.

This library is not necessary nor recommended when targeting versions of .NET that include the relevant support.

Using Range with Arrays

The C# compiler needs the RuntimeHelpers.GetSubArray<T> method to be available to create subranges from arrays. This method is only available in netstandard2.1 and .NET Core 3.0, so creating subranges from arrays will fail to compile in .NET Framework.

Use Span<T>

A workaround is to add a reference to System.Memory and use Span<T>. Not only does this compile, it's much more efficient as it doesn't create a new array and copy the sliced data to it:

int[] array = new[] { 1, 2, 3, 4, 5, 6 };

// don't do this:
// var slice = array[1..^1];

// do this:
var slice = array.AsSpan()[1..^1];

Define GetSubArray<T>

The other fix is to define the necessary method in your source code. Copy the following code into your project:

That type is not in this NuGet package so that the C# compiler doesn't warn that The predefined type 'RuntimeHelpers' is defined in multiple assemblies.
