re: Dealing with Nothing in C# - The Null Object Pattern VIEW POST

re: The next version of C# will make huge strides toward making null a nonissue. Nullable reference types.

AFAIK there are currently measures to deal with null issues in C#

They are:

Nullable types System.Nullable<T>

int? Id = null;

Default literal

int i = default;

Null coalescing operator

int currentUserId = getUserId() ?? -1;

Null conditional operator

var userObject = null;
try {
catch {
finally {

Nullable value types introduced the concept of null where previously a value couldn’t be null. (It’s essentially an option type.) The rest of these were introduced as syntactic sugar to help us deal with the fact that null exists in the language. In upcoming versions of C# you will be able to opt into nullability. Soon, the default mode of operation in C# will be “things can’t be null”.

So that’s exactly what I think you’re missing here. In upcoming versions, you won’t need those annotations. Take some time to look into Nullable reference types.

I think it's far from being ready. Especailly if it introduces breaking changes. Switching midsets is difficult and if you hide a feature behind a compiler switch it's not going to work.

By the way John Skeet found 2 bugs straight away...
