通过提供类名称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：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，，但没有一个答案有效。

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，该项目从包含普通类型作为字符串的数据库中提取数据。这些类型在引用的程序集中，而不在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.

因此，例如，假设我的引用程序集名称为 MyFramework 和普通类型名称 Car ，完整类型名称可以是 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引用的程序集名称和普通类名称。

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中使用该函数吗？项目，这样我就可以放弃包括程序集名称的内容了吗？我想删除知道程序集名称的信息，所以我想可以在引用的程序集中编写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项目中我可以调用它而无需将程序集作为字符串名称。可以吗？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

也许引用的程序集当时未加载。另外，从您的问题中我了解到您没有完整的类型名称，只有类名称。

您应该尝试以下方法：

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。
