我可以使用隐式转换器将常见值类型（例如Int32）的类型转换扩展到我的自定义类型吗？

Question

What if i need some kind of reference type wrapper for Int32 (the database Id for example). How can i convert Int32 to my class implicitly?

Answer 1

Create a static implicit converter operator:

public class MyClass
{
    ....
    static public implicit operator MyClass(int value)
    {
        // Create a new instance of your class using the value.
    }
    ...
}

Once created, you can do something like this:

MyClass myInstance = 48;
