If you want to check the property value or string which is Null or not using the following code in c# .Net.
Employee emp = new Employee();
emp.firstname = "Thivan";
if (!string.IsNullOrEmpty(emp.firstname.ToString()))
{
//your code here
return true;
}
else {
//your code here
return false;
}
The above example clears how to use IsNullOrEmpty, which will return true or false. It indicates whether the property value or string is empty or null.
