Have you ever considered of searching on a list based upon a single value, for example we have a List
There are many ways to search for it, we can walk through a foreach loop, or call our database, or whatsoever But we also have functions called Find and FindAll that expects a function the returns a bool value.
Now how we can use it. Suppose we are having a list of Employees say :
and we want to search an employee that contains EmpCode = 0.
We can write a function like:
int _empCode = 4;
Employee empWithCode = lstEmployee.FindAll(new Predicate
private void GetSingleEmployeeForCode
if (emp.EmpCode == _empCode)
This will return us the employee with EmpCode 4.
Now how can we search for items that may have same value for different objects in list.
We have function like :
maleEmpList = lstEmployee.FindAll(new Predicate
private void GetMaleEmployees (Employee emp)
if (emp.Gender == "Male")
