In functions with long parameter list, I wrap after each one or two parameters for readability (always keeping the same number of parameters on each line):
int SomeReturnValue = SomeMethodWithLotsOfArguments(Argument1,
Argument2,
Argument3,
Argument4);
OR
int SomeReturnValue = SomeMethodWithLotsOfArguments(Argument1, Argument2,
Argument3, Argument4);
depending on the list/parameter length.
