Why use the ref keyword when passing an object? 4 By using the ref keyword with reference types you are effectively passing a reference to the reference In many ways it's the same as using the out keyword but with the minor difference that there's no guarantee that the method will actually assign anything to the ref 'ed parameter
What is the use of ref for reference-type variables in C#? Without ref, the reference is passed by value, and this doesn't happen C# also has the 'out' keyword which is a lot like ref, except that with 'ref', arguments must be initialized before calling the method, and with 'out' you must assign a value in the receiving method
Whats the difference between the ref and out keywords? ref means that the value in the ref parameter is already set, the method can read and modify it Using the ref keyword is the same as saying that the caller is responsible for initializing the value of the parameter
When to use in vs ref vs out - Stack Overflow out and ref parameters are marshaled differently when dealing with interop code Also, as an aside, it's important to note that while reference types and value types differ in the nature of their value, every variable in your application points to a location of memory that holds a value, even for reference types
