Why is there no Char.Empty like String.Empty?

I want to pass an empty char as a method parameter and I was wondering why I cannot say

char.Empty

while C# allows me to specify string.Empty ?

If not do I have '' as the only option ?

Answer 1

There is no empty char same way there is no empty number.

You can try using "null" character:

char empty = '\0';

Answer 2

You can use for identifying empty char:

default(Char)

Answer 3

There is no such thing as an empty char. You would need to use nullable types to introduce that concept.

char? c = null;
