Is a bool read/write atomic in C#
.net, boolean, c#, concurrency, locking
Solution
Yes.
Reads and writes of the following data types are atomic: bool, char, byte, sbyte, short, ushort, uint, int, float, and reference types.
as found in C# Language Spec.
Edit: It's probably also worthwhile understanding the volatile keyword.
Problem
Is accessing a bool field atomic in C#? In particular, do I need to put a lock around: ``` class Foo { private bool _bar; //... in some function on any thread (or many threads) _bar = true; //... same for a read if (_bar) { ... } } ```
