Question

I am aware that I can set null like

string val = null;

But I am wondering the other ways I can set it to null. Is there a funcion like String.null that I can use.

Answer 1

I think you are looking far String.Empty

string val = String.Empty;

Update:
TheFuzzyGiggler comments are worth mentioning:

It’s much better to set a string to empty rather than null. To avoid
exceptions later. If you have to read and write a lot of strings
you’ll have null value exceptions all over the place. Or you’ll have a
ton of if(!string.isNullorEmpty(string)) which get annoying
