Is there a way to ensure a function can't modify a parameter?
I often want to pass objects or values into a function, and make sure the function cannot change it... is it possible?
Example scenario:
Example scenario:
public void UpdateUserAge() {
var user = _dbContext.Users.Find(4);
user.Age = 111;
// How to make sure WriteUserLog can not modify user?
WriteUserLog(user);
_dbContext.SaveChanges()
]
private void WriteUserLog(UserEntity user) //can this parameter be made readonly somehow?
{
user.Name = "Shouldnt be able to change this";
Console.WriteLine($"User {user.Age} was changed")
}
