Examples
Using computed properties in linq.
Asume we have a class with a computed property
class Employee
{
[Computed]
public string FullName => FirstName + " " + LastName;
public string LastName { get; set; }
public string FirstName { get; set; }
}
And you are going to query employees by their full names
var employees = (from employee in db.Employees
where employee.FullName == "Test User"
select employee).Decompile().ToList();
When you call .Decompile method it decompiles your computed properties to their underlying representation and the query will become simmilar to the following query
var employees = (from employee in db.Employees
where (employee.FirstName + " " + employee.LastName) == "Test User"
select employee).ToList();
If your class doesn't have a [Computed] attribute, you can use the .Computed() extension method..
var employees = (from employee in db.Employees
where employee.FullName.Computed() == "Test User"
select employee).ToList();
