How to pass variables to overridden toString() method?

Question

Is it possible to pass in a bool variable into an overridden toString() method, so it can conditionally print the object in different formats?

Answer 1

The typical pattern for parametrized ToString() is to declare an overload with a string parameter.

Example:

class Foo
{
    public string ToString(string format)
    {
        //change behavior based on format
    }
}

For a framework example see Guid.ToString
