要继承C＃System.Type的最简单的方法最简单、方法、System、Type
我需要定点数的类继承System.Type的。
I need to make fixed point number class inherit from System.Type.
class FixedPoint : Type
{
public bool Signed { get; set; }
public int Width { get; set; }
public int IntegerWidth { get; set; }
public FixedPoint(Boolean signed = false, int width = 16, int integerWidth = 8)
{
Signed = signed;
Width = width;
IntegerWidth = integerWidth;
}
}
当我试图编译这个code，我得到的错误信息说我需要实现方法为类型是抽象类。
When I tried to compile this code, I got error messages saying that I need to implement methods as Type is abstract class.
userdef.cs(3,7): error CS0534: 'FixedPoint' does not implement inherited abstract member 'System.Type.GUID.get'
userdef.cs(3,7): error CS0534: 'FixedPoint' does not implement inherited abstract member 'System.Type.Namespace.get'
c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll: (Location of symbol related to previous error)
userdef.cs(3,7): error CS0534: 'FixedPoint' does not implement inherited abstract member
'System.Type.AssemblyQualifiedName.get'
我怎样才能避免这些错误信息？有没有简单的方法来继承类型？我一定要实现所有的方法呢？如果是这样，是否有这样做的任何引用？
How can I avoid those error messages? Is there any easy way to subclass Type? Do I have to implement all the methods? If so, are there any references for doing that?
或
时的子类价值型的工作努力？我确实需要继承类型的一些原因，如果这真的很难做到这一点。我最好放弃早早另谋出路。
Is the work of subclassing Type worth trying? I do need to subclass Type for some reasons, if it's really hard to do it. I'd better give up early to find another way.
推荐答案
你说你有你的理由从的System.Type 继承，即使我同意@mootinator ，这里有一些回答您的其他问题：
You say you have your reasons for inheriting from System.Type, even though I agree with @mootinator, here are some answers to your other questions:
有没有简单的方法来继承类型？
Is there any easy way to subclass Type?
没有。
我一定要实现所有的方法？
Do I have to implement all the methods?
是的。
如果是这样，没有做任何的参考？
If so, are there any references for doing that?
您的覆盖 -keyword添加到每个属性和方法
You add the override-keyword to each of the Properties and Methods
这是你如何开始一个例子，你需要覆盖每个摘要属性和方法
This is an example of how you start off, you need to override each of the abstract properties and methods.
public class Test : Type
{
public override Guid GUID
{
get { throw new NotImplementedException(); }
}
}
这是一个完整的compileable 类，它覆盖所有的属性和方法这是必要的，但没有实现。
This is a complete compileable class that overrides all the properties and methods that is needed, but nothing is implemented.

As you can see, there are quite a few that you need to override in order to remove all the compilation errors, so either you have a really good reason for wanting to do this or you should think about overriding from another class/struct or just create a new class/struct.
