通过提供类名作为字符串来获取引用程序集中的类型? [英] Get type in referenced assembly by supplying class name as string?

问题描述

这些是类似的问题:操作方法:在运行时使用 Silverlight 中的字符串从引用的程序集中加载类型，对引用程序集中的类进行 GetType 失败，但两个答案都不起作用.

These are similar questions: How-to: Load a type from a referenced assembly at runtime using a string in Silverlight, GetType on a class in a referenced assembly fails but neither answer works.

我有一个 MVC 项目，它从一个数据库中提取数据，该数据库包含作为字符串的普通类型.这些类型在引用的程序集中，而不是在 MVC 项目中.

I've got an MVC project that pulls data from a database that includes the plain types as strings. These types are in a referenced assembly, not in the MVC project.

例如，假设我的引用程序集名称是 MyFramework 和普通类型名称 Car，完整的类型名称可以是 MyFramework.Cars.Car 或 MyFramework.Vehicles.Cars.Car 或其他一些变体.我所拥有的只是作为字符串的引用程序集名称和普通类名称.无论完整的类型名称如何，如何获取类型?

So for example let's say my Referenced Assembly Name is MyFramework and the plain type name Car, the full type name could be MyFramework.Cars.Car or MyFramework.Vehicles.Cars.Car or some other variation. All I have are the referenced assembly name and plain class name as strings. How can I get the type regardless of the full type name?

最后，我可以在引用的程序集中编写一个调用 GetType() 的函数并在 MvC 项目中使用它，以便我可以放弃包含程序集名称吗?我想删除知道程序集名称的信息，所以我想我可以在引用的程序集中编写一个 Util ，例如:

Finally, could I write a function in the referenced assembly that calls GetType() and use that in the MvC project so I could forego including the assembly name? I want to remove knowing the assembly name so I thought I could write a Util IN the referenced assembly like:

namespace MyFramework //the referenced assembly
{
  public static class TypeUtil
  {
    public static Type GetFrameworkType(string typeName)
    {
        return Type.GetType(typeName);
    }
  }
}

然后在我的 MVC 项目中，我可以在不需要程序集作为字符串名称的情况下调用它.这是可能的还是我总是需要程序集名称?

And then in my MVC project I could call it without needing the assembly as a string name. Is that possible or will I always need the assembly name?

推荐答案

可能当时没有加载引用的程序集.另外，我从您的问题中了解到您没有完整的类型名称，只有类名.
你应该尝试沿着这条线做一些事情:

Maybe the referenced assembly isn't loaded at the time. Also, I understand from your question that you do not have the full type name, only the class name.
You should try something along this line then:

Type type = Assembly.Load("YourAssemblyName").GetTypes().First(t => t.Name == "ShortTypeName");

希望我理解正确.
