Exactly what the error says.

You define this[string] here:

string this[string lineBreaks]
{
    get
    {
        //...
    }
}

Then you define it again here:

string this[string lineBreaks]
{
    get
    {
        //...
    }
}

You can only define members of the same signature once. Otherwise the code would have no way of knowing which one you're trying to invoke when you invoke it.
