[Solved] Does c#’s ref copy and how to prevent it? [duplicate]

by


The ref keyword is used to pass an argument by reference, not value. The ref keyword makes the formal parameter alias for the argument, which must be a variable. In other words, any operation on the parameter is made on the argument.

For example:

void Method(ref int refArgument)
{
    refArgument = refArgument + 44;
}

int number = 1;
Method(ref number);
Console.WriteLine(number);
// Output: 45

So to answer your question, no the ref keyword does not “copy” the variable.
