DelegateDecompiler

A tool which is able to decompile a delegate or a method body to its lambda representation

Examples

Using computed properties in linq.

Asume we have a class with a computed property

class Employee
{
    [Computed]
    public string FullName
    {
      get { return 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();
