Simply install nuget package and you are ready to zoom off!

Creating a new class

var className = "ClassA";
var typeExtender = new TypeExtender(className);
var returnedType = typeExtender.FetchType();
var obj = Activator.CreateInstance(returnedClass);

Extending an existing class

var className = "ClassA";
var baseType = typeof(List<string>);
var typeExtender = new TypeExtender(className, baseType);
var returnedClass = typeExtender.FetchType();
var obj = Activator.CreateInstance(returnedClass);

Adding CustomAttribute to type

 var typeExtender = new TypeExtender("ClassA");
 typeExtender.AddAttribute<CustomAAttribute>(new object[] { "Jon Snow" });

Adding Properties to type

There are several overloads on the AddProperty method. Few of them are shown below:

var typeExtender = new TypeExtender("ClassA");
typeExtender.AddProperty("IsAdded", typeof(bool));
typeExtender.AddProperty("IsEnabled", typeof(bool), true);
typeExtender.AddProperty<double>("Width", true);

You can add properties with custom attributes

 var attributeType = typeof(CustomAAttribute);
 var attributeParams = new object[] { "Jon Snow" };
 var typeExtender = new TypeExtender("ClassA");
 typeExtender.AddProperty("IsAdded", typeof(bool), attributeType, attributeParams);

Adding Field to Type

The AddField method helps add a field to the type you are creating or extending

  var typeExtender = new TypeExtender("ClassA");
  typeExtender.AddField("IsAdded", typeof(bool)); // first overload
  typeExtender.AddField<bool>("IsEnabled"); // second overload
