✅ Finding all FieldInfo's of BackingFields of a type

I have following code snippet to find all

FieldInfo

FieldInfo

FieldInfo

FieldInfo's of a type

t

t which are BackingFields of public properties of type double.

FieldInfo[] doubleFields = t
    .GetProperties(BindingFlags.Public | BindingFlags.Instance)
    .Where(p => p.PropertyType == typeof(double))
    .Select(p => t.GetField($"<{p.Name}>k__BackingField", BindingFlags.NonPublic | BindingFlags.Instance)!)
    .Where(f => f is not null)
    .ToArray();

FieldInfo[] doubleFields = t
    .GetProperties(BindingFlags.Public | BindingFlags.Instance)
    .Where(p => p.PropertyType == typeof(double))
    .Select(p => t.GetField($"<{p.Name}>k__BackingField", BindingFlags.NonPublic | BindingFlags.Instance)!)
    .Where(f => f is not null)
    .ToArray();

FieldInfo[] doubleFields = t
    .GetProperties(BindingFlags.Public | BindingFlags.Instance)
    .Where(p => p.PropertyType == typeof(double))
    .Select(p => t.GetField($"<{p.Name}>k__BackingField", BindingFlags.NonPublic | BindingFlags.Instance)!)
    .Where(f => f is not null)
    .ToArray();

FieldInfo[] doubleFields = t
    .GetProperties(BindingFlags.Public | BindingFlags.Instance)
    .Where(p => p.PropertyType == typeof(double))
    .Select(p => t.GetField($"<{p.Name}>k__BackingField", BindingFlags.NonPublic | BindingFlags.Instance)!)
    .Where(f => f is not null)
    .ToArray();

I was now wondering if the

CompilerGeneratedAttribute

CompilerGeneratedAttribute

CompilerGeneratedAttribute

CompilerGeneratedAttribute is only applied to BackingFields or if there are other instances of fields having that attribute since I cannot currently think of any. If it is only applied to BackingFields, I could skip the step of getting all properties.

I just had the bright idea of asking ChatGPT the exact same and, for once, it actually knew something. Now that I've seen it it's obvious but compiler generated fields are also created when you use asyncasync or yield returnyield return.
