Jcd.Reflection

A dotnetstandard2.0 library containing some commonly implemented reflection helpers.

v2.0 has many breaking changes. See the Version History for details.

Examples

    internal static class Program
    {
        private static void Main()
        {
            var c = new TestClass();
            // set the private field, _field
            c.SetValue("_field",10);

            // now get its value.
            var val = (int)c.GetValue("_field");
            Console.WriteLine(val);

            // Now set a private property with a backing field.
            c.SetValue("PrivateProperty",20);

            // Now call a private helper method that returns the value from the backing field.
            val = c.Invoke<int>("InternalGetField");
            Console.WriteLine(val);

Special Thanks To

Scrutor inspired the technique I'm using for finding implementations of specific types as well as a couple of other handy utility methods.

v2.0 Breaking Changes

Version 2.0 comes with a significant number of breaking changes for advanced use cases. These are listed below

  • ExpandoObjectExtensions was removed. It wasn't functioning as planned. An overhaul of the approach is needed.
  • All overloads of FilterMethods were renamed to GetMethods
  • The filter parameter was moved to the last parameter on an overload of GetMethods (formerly FilterMethods).
  • Renamed EnumerationSettings to Filter in MemberInfoEnumerator, FieldOrPropertyEnumerator, and MethodInfoEnumerator
  • Moved and renamed type from MethodInfoEnumerator.Settings to MethodInfoFilter.
  • Moved predefined instances of MethodInfoEnumerator.Settings from MethodInfoEnumerator to MethodInfoFilter.
  • Moved and renamed type from MemberInfoEnumerator.Settings to MemberInfoFilter.
  • Moved and renamed type from FieldOrPropertyEnumerator.Settings to FieldOrPropertyInfoFilter.
  • MethodInfoFilter, MemberInfoFilter, FieldOrPropertyInfoFilter fields are now get-only properties, requiring a call to new to create new instances.
  • To facilitate the use of init properties on MethodInfoFilter, MemberInfoFilter, FieldOrPropertyInfoFilter types, a custom IsExternalInit is required of target frameworks not supporting it. See this project's source code for an example (IsExternalInit.cs).
  • Extension methods GetCusomAttributes and HasAttribute were moved into classes named after the underlying method. This will only break non-extension invocations.
