High-Performance Memory Management with Span

Span<T> represents a contiguous region of memory. It allows for high-performance operations like slicing arrays without creating expensive copies. It is especially useful in performance-critical applications where memory allocation needs to be minimized.

snippet.cs

csharp

public void UpdateValues(int[] data)
{
    // Create a window (slice) into the array without copying it
    Span<int> slice = data.AsSpan(1, 3);
 
    for (int i = 0; i < slice.Length; i++)
    {
        slice[i] *= 10; // Directly modifies the original 'data' array
    }
}

Breakdown

Span<int> slice = data.AsSpan(1, 3);

Creates a view of 3 elements starting at index 1 of the original array.

slice[i] *= 10;

Modifies the memory in-place; changes are reflected in the original 'data' array.
