Edit Question
Title
Body
Assume I have a business object like this, class Employee { public string name; public int id; public string desgination; public int grade; } List<Employee> lstEmp = new List<Employee>() { new Employee() { name="A",desgination="SE",id=1}, new Employee() { name="b",desgination="TL",id=2}, new Employee() { name="c",desgination="PL",id=3}, new Employee() { name="d",desgination="SE",id=4}, new Employee() { name="e",desgination="SSE",id=5}, }; And if I want to update the employee grade to 3 whose designation is "SE", then I have to write something like this lstEmp=lstEmp.Select(x => { x.grade = (x.desgination == "SE") ? 3 : x.grade; return x; }).ToList(); But here when using select it will generate new employee object everytime, not updating the existing lstEmp, so I have to reassgin the updated list to lstEmp. It seems to me it affects the performance when updating large updates frequently. Is there a workaround for this?
