博客介绍了数据类型的原子读写情况，指出uint、int、float和引用类型等的读写是原子的，enum类型在特定条件下读写也为原子的。而long、ulong等类型及用户定义类型的读写不一定是原子的，除特定库函数外，也无法保证原子的读-修改-写操作。
uint, int, float, and reference types. In addition, reads and writes of enum
types with an underlying type
in the previous list shall also be atomic. Reads and writes of other types,
including long, ulong, double,
and decimal, as well as user-defined types, need not be atomic. Aside from
the library functions designed
for that purpose, there is no guarantee of atomic read-modify-write, such
as in the case of increment or
decrement.
