C＃泛型能有一个特定的基类型吗？ [英] Can C# generics have a specific base type?

问题描述

泛型接口的类型是否可能基于特定的父类？

例如：

  public interface IGenericFace< T：BaseClass> 
 {
} 
  

显然上面的代码不起作用，但如果它做了什么，我试图告诉编译器： T 必须是 BaseClass 的子类。可以这样做，是否有计划等等？

我认为这对于一个特定的项目是有用的，确保一个通用的接口/类不是在编译时没有使用非预期的类型。或者也可以对自我文档进行排序：显示哪种类型是有意的。

解决方案 > public interface IGenericFace< T> T：SomeBaseClass

Is it possible for a generic interface's type to be based on a specific parent class?

For example:

public interface IGenericFace<T : BaseClass>
{
}

Obviously the above code doesn't work but if it did, what I'm trying to tell the compiler is that T must be a sub-class of BaseClass. Can that be done, are there plans for it, etc.?

I think it would be useful in terms of a specific project, making sure a generic interface/class isn't used with unintended type(s) at compile time. Or also to sort of self-document: show what kind of type is intended.

解决方案

public interface IGenericFace<T> where T : SomeBaseClass
