Difference between ref
and out
parameters in C#
In C#, both `ref` and `out` parameters are used to pass arguments by reference to a method. However, there are key differences between them:
ref
Parameters:
- Must be initialized before passing to the method.
- Method can read and modify the value of `ref` parameter.
- Changes made to the `ref` parameter inside the method are reflected outside the method.
out
Parameters:
- Do not need to be initialized before passing to the method.
- Method must initialize the `out` parameter before returning.
- Designed to return a value from a method.
It is important to choose between `ref` and `out` parameters based on the specific requirements of your method and how you intend to use the passed arguments.
