This code checks whether the `Country` property of the `employeeModel`...

This code checks whether the Country property of the employeeModel object is not null, empty, or consists only of whitespace characters. If this condition is true (i.e., the Country has a meaningful value), it assigns the value of employeeModel.Country to the ForeignCountry property of the employeeAddress object.

To break it down:

• !string.IsNullOrWhiteSpace(employeeModel.Country):

  • string.IsNullOrWhiteSpace is a method that checks if a string is null, empty (""), or consists only of whitespace characters (e.g., space, tab, etc.).
  • The ! negates the result. This means the condition checks if employeeModel.Country is NOT null, empty, or whitespace only.

• employeeAddress.ForeignCountry = employeeModel.Country;:

  • If the condition is met, the value of employeeModel.Country is assigned to employeeAddress.ForeignCountry.

Overall, the code ensures that employeeAddress.ForeignCountry only gets assigned a valid, meaningful value from employeeModel.Country.
