Trying to save null value with arcObjects

I'm trying to save a null in an integer column with arcObjects but it always save 0 when the value is null. Can anyone explain me what is happening? I am developing in C#.

I tried to assign DBNull.Value to my variable but I can't because it's an integer. Thank you very much for your time and your knowledge!

Shapefile does not support Null in field value and converts it to default value ie 0 for integer types. In a Geodatabase, the field "Allow NULL values" property should be set to "Yes".
