通过反射/类型名实例化一个泛型类 [英] Instantiating a generic class through reflection / typename
本文介绍了通过反射/类型名实例化一个泛型类的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
public class Repository< T>
{
public IEnumerable< T> FindAll()
{
//
}
}
我希望能够做的是通过反射来创建Repository的一个实例。
例如:
var typeName =Customer
var type = Assembly.GetCallingAssembly()。GetType(typeName);
//显然,这是无效的...
var repository = new Repoistory< type>();
是否有这些可能?
解决方案
var repository = Activator.CreateInstance(typeof(Repository<>)。MakeGenericType(type));
For example, I have a class, that looks like:
public class Repository<T>
{
public IEnumerable<T> FindAll()
{
//
}
}
What I'd like to be able to do, is create an instance of a Repository via reflection.
For example:
var typeName = "Customer"
var type = Assembly.GetCallingAssembly().GetType(typeName);
//obviously, this isn't valid...
var repository = new Repoistory<type>();
Is something along these lines possible?
解决方案
var repository = Activator.CreateInstance(typeof(Repository<>).MakeGenericType(type));
