.Net Parameter Attribute to make named/optional Parameter visible only internally/private?

Question

Out of curiosity, is there a way to write a method e.g. like this:

public static MyType Parse(string stringRepresentation, [Internal] bool throwException = true)
{
// parsing logic here that conditionally throws an exception or returns null ...
}

public static MyType TryParse(string stringRepresentation)
{
return this.Parse(stringRepresentation, true);
}

I want to cut down code redundancies internally, but remain compliant to e.g. BCL method signatures for (Try)Parse() but if the c# compiler could in this case generate a second, internal method that would be nice.

Is that already somehow possible? Couldn't find anything so far.

I'm not aware that you can, but wouldn't this give you the same result?

public MyType Parse(string stringRepresentation)
{
    return this.Parse(stringRepresentation, true);
}

internal MyType Parse(string stringRepresentation, bool throwException = true)
{
    // parsing logic here that conditionally throws an exception or returns null ...
}
