Just curious.
If you go:
string myString;
Its value is null.
But if you go:
int myInt;
What is the value of this variable in C#?
Thanks

Firstly, note that this is only applicable for fields, not local variables – those can’t be read until they’ve been assigned, at least within C#. In fact the CLR initializes stack frames to 0 if you have an appropriate flag set – which I believe it is by default. It’s rarely observable though – you have to go through some grotty hacks.
The default value of
intis 0 – and for any type, it’s essentially the value represented by a bit pattern full of zeroes. For a value type this is the equivalent of calling the parameterless constructor, and for a reference type this is null.Basically the CLR wipes the memory clean with zeroes.
This is also the value given by
default(SomeType)for any type.
