This project uses Source Generation to generate an interface and a Proxy class for classes. This makes it possible to wrap external classes which do not have an interface, in a Proxy class which makes it easier to Mock and use DI.
It supports:
- properties
- methods
- events
- implicit and explicit operators
public sealed class Person
{
public string Name { get; set; }
public string HelloWorld(string name)
{
return $"Hello {name} !";
}
}And annotate this with ProxyInterfaceGenerator.Proxy[...] and with the Type which needs to be wrapped:
[ProxyInterfaceGenerator.Proxy(typeof(Person))]
public partial interface IPerson
{
}In case also want to proxy the properties/methods/events from the base class(es), use this:
[ProxyInterfaceGenerator.Proxy(typeof(Person), true)] // 👈 Provide `true` as second parameter.
public partial interface IPerson
{
}By default, the generated Proxy class is public. If you want to create the Proxy class as internal, use the following:
[ProxyInterfaceGenerator.Proxy(typeof(Person), ProxyClassAccessibility.Internal)] // 👈 Provide `ProxyClassAccessibility.Internal` as second parameter.
public partial interface IPerson
{
}Which defines the same properties and methods as in the external class.
public partial interface IPerson
{
string Name { get; set; }
string HelloWorld(string name);
}Which takes the external class in the constructor and wraps all public properties, events and methods.
// ⭐
public class PersonProxy : IPerson
{
public Person _Instance { get; }
public PersonProxy(Person instance)
{
_Instance = instance;
}
public string Name { get => _Instance.Name; set => _Instance.Name = value; }
public string HelloWorld(string name)
{
string name_ = name;
var result_19479959 = _Instance.HelloWorld(name_);
return result_19479959;
}
}⭐ By default the accessibility from the generated Proxy class is public.
IPerson p = new PersonProxy(new Person());
p.Name = "test";
p.HelloWorld("stef");You can ignore members by adding a property to the membersToIgnore string array.
Example when you want to ignore the Postcode property:
[Proxy(typeof(Address), ["Postcode"])]
public partial interface IAddress
{
}Note that's also possible to use wildcard matching to ignore multiple members at once.
[Proxy(typeof(Address), ["Post*"])]
public partial interface IAddress
{
}
