c# - "C# base class virtual function"- "override in Managed C++ ref class"

Question

我有一个 .NET_4 Managed C++ ref 类，它派生自用 C# 编写的 .NET_4 基类。

C# 基类:

namespace Core
{
  public class ResourceManager
  {
    public class _Resource
    {
      public virtual void Delete() {}
    }
  }
}

托管 C++ 类:

namespace Input.DI
{
  public ref class Mouse : ResourceManager::_Resource
  {
    public:
    virtual void Delete() {}
  };
}

这是我遇到的错误:

'Input::DI::Mouse::Delete' : matches base ref class method 'Core::ResourceManager::_Resource::Delete', but is not marked 'new' or 'override'; 'new' (and 'virtual') is assumed

从 C# 类覆盖 virtual 函数的正确托管 C++ 语法是什么？

Answer 1

你把 override after the function signature .

//MANAGED C++ CLASS
namspace Input.DI
{
  public ref class Mouse : ResourceManager::_Resource
  {
    public:
    virtual void Delete() override {}
  };
}
