c# check if null or empty ofr int code example

Example: c# check if int is null

// When trying to check if your int is null or i.e. 'not set',
// you will get the following error:

// The result of the expression is always 'false'
// since a value of type 'int' is never equal to 'null' of type 'int?'

// You can however bypass this by converting your int to string:
int myInt = null;
// This Method will return a bool;
bool isNullInt = string.IsNullOrEmpty(myInt.ToString());
// isNullInt will be in this case true
