Delegate在.net核心中不包含CreateDelegate的定义

Question

I'm trying to use delegates for reflection in dotNet core web application. Below is the sample of the code.

Action action = (Action) Delegate.CreateDelegate(typeof(Action), method)

Compiler gives the following error:

'Delegate' does not contain a definition for 'CreateDelegate'   ConsoleApp2..NETCoreApp,Version=v1.0'

Is there any work around for creating delegates in .net Core?

Answer 1

Use MethodInfo.CreateDelegate instead.

MethodInfo methodInfo = target.GetType().GetMethod(nameof(FooMethod));

Action action = (Action) methodInfo.CreateDelegate(typeof(Action), target);

Delegate.CreateDelegate is expected to return in .NET Core 2.0: .NET API Catalog
