Use of 'ref' keyword in C# [duplicate]

Answer 1

I believe the ref keyword indicates that you are passing the object by reference, not by value. For example:

void myfunction(ref object a) {
a = new Something();
}

would change the value of a in the calling function However,

void myfunction(object a) {
a = new Something();
}

would change the value of a locally, but not in the calling function. You can still change PROPERTIES of the item, but you cannot set the value of the item itself. For example; a.someproperty = value;

would work in both cases.
