How does C# manage uninitialized classes?

Question

I am using C# in Unity and I need to know how does C# manages classes in order to know if I need to set all of the values during or after the new to avoid invalid reads or if I can leave them as they are.

With this example I get the following output :

class Test {
  public int test;
}
Test buffer = new Test;
Debug.Log(buffer.test);

0
UnityEngine.Debug:Log(Object)

Does this mean the variable types all have a default value or should I be more careful when instantiating a Class ?

.Net框架将所有字段初始化为其默认值（ 0或null ）。
