从通用类型转换为具体类型的最干净方法

Question

I have a method

public Dto Convert<T>(T source)
{
   //todo here?
}

And i need to call the following methods from there based on T, will i have to do TypeOf and switch statement (trying to avoid that)?

public Dto Convert(Contact source) {}
public Dto Convert(Org source) {}
etc...

Answer 1

You could use dynamic :

public Dto Convert<T>(T source)
{
   var resut = (Dto)Convert((dynamic)source);
}

It will perform method selection at runtime depending on actual source type. Will also fail when there is no suitable method with that name available.

But it seems to be something wrong with your design in general. Are you sure you're not trying to solve XY problem ?
