6 months ago Hi, thanks for reporting the issue, at the moment I can't reproduce this. My test code:
using System.Collections;
using System.Runtime.CompilerServices;
internal class Program
{
private static void Main(string[] args)
{
Console.WriteLine("Hello, World!");
var list = new ListStruct<int>();
var value = list[0];
}
}
public struct ListStruct<T> : IEnumerable<T> where T : unmanaged
{
internal int CountInternal;
private T[] _storage;
// ...
public readonly ref T this[int index]
{
[method: MethodImpl(MethodImplOptions.AggressiveInlining)]
get => ref _storage[index];
}
public IEnumerator<T> GetEnumerator()
{
throw new NotImplementedException();
}
IEnumerator IEnumerable.GetEnumerator()
{
throw new NotImplementedException();
}
}I guess some additional code is required to trigger the issue.
My sample code is dotnet 8.0, I tested with the analyzer from 6.0, 7.0 and 8.0. But none failed.
Akarinnnnn
I made a specialized collection for mutable large structs. To mutate a struct member by this indexer, it returns a reference. While analyzer processing this file, it thrown an exception and stopped generation.
Here is the repro code snippet:
And here is the stack trace:
Hope these information will help.
