Stackalloc in nested expressions

Hi Ayesha Sk,

The use of 'Stackalloc' in nested expressions as like as following:

Starting with C# 8.0, if the result of a stackalloc expression is of the System.Span or System.ReadOnlySpan type, you can use the stackalloc expression in other expressions:

Span<int> numbers = stackalloc[] { 1, 2, 3, 4, 5, 6 };
var ind = numbers.IndexOfAny(stackalloc[] { 2, 4, 6, 8 });
Console.WriteLine(ind);
// output: 1

Hope, this will help you!
