像往常一样，您应该阅读文档并进行自己的研究.
最终确定 [处置 [

As usual you should be reading the documentation and doing your own research.
Finalize[^]
Dispose[^]

Finalize()
1.这与C#中的析构函数~Object()语法在C#中等效.
在VB.Net中，您可以通过覆盖实现Finalize().但是，在C#中，编译器将析构函数转换为Finalize()方法.
2. Finalize()不能在C#中覆盖或调用.
3.因为Finalize()由垃圾收集器调用，所以它是不确定的.

Dispose()
1.这必须在实现IDispose interface的类中实现. 2.它是释放非托管资源(例如文件，句柄和连接等)的正确位置.
3. Dispose()方法在代码本身中被显式调用.
4.在"using"语句中使用时，Dispose()方法将自动调用(对于实现IDispose的对象).

Finalize()
1.This is the C# equivalent of destructor ~Object() syntax in C#.
In VB.Net you implement the Finalize() by overriding it. But, in C# the compiler translates the destructor to a Finalize() method.
2. Finalize() can NOT be overridden or called in C#.
3. Since, Finalize() is called by the Garbage Collector, it is non-deterministic.

Dispose()
1. This has to be implemented in classes implementing IDispose interface.
2. Its the right place for freeing-up unmanaged resources like file, handles, and connections etc.
3. Dispose() method is called explicitely in the code itself.
4. Dispose() method is automatically called (for objects which implement IDispose), when used in a "using" statement.
