获取在.NET Core中实现接口的所有类型 [英] Getting all types that implement an interface in .NET Core

问题描述

使用反射，如何获得在 .NET Core 中实现某些特定接口的所有类型?我注意到，在.NET 4.6中可用的方法不再可用.

Using reflection, How can I get all types that implement some specific interface in .NET Core? I have noticed that the methods usable in .NET 4.6 are not available anymore.

例如，此代码不起作用.

For example, this code doesn't work.

var type = typeof(IMyInterface);
var types = AppDomain.CurrentDomain.GetAssemblies()
    .SelectMany(s => s.GetTypes())
    .Where(p => type.IsAssignableFrom(p));

它抛出名称"AppDomain"在当前上下文中不存在错误.

推荐答案

您可以这样做:

System.Reflection.Assembly ass = System.Reflection.Assembly.GetEntryAssembly();

foreach (System.Reflection.TypeInfo ti in ass.DefinedTypes)
{
    if (ti.ImplementedInterfaces.Contains(typeof(yourInterface)))
    {
        ass.CreateInstance(ti.FullName) as yourInterface;
    }  
}

如果要在所有程序集中输入类型，只需使用以下命令即可获取所有引用，然后再次执行上述操作:)

If you want types in all assemblies, just simply use the following to get all the references and do the above again:)

ass.GetReferencedAssemblies()
