我试图避免在我的主项目中引用具体类型库,但我收到了这个错误:
No default instance or named instance 'Default' for requested plugin type StackExchangeChatInterfaces.IClient
1.) Container.GetInstance(StackExchangeChatInterfaces.IClient ,{username=; password=; defaultRoomUrl=; System.Action`2[System.Object,System.Object]=System.Action`2[System.Object,System.Object]})
我已经设置我的容器来扫描程序集,如下所示:
var container = new Container(x =>
{
x.Scan(scan =>
{
scan.AssembliesFromApplicationBaseDirectory();
scan.ExcludeNamespace("StructureMap");
scan.WithDefaultConventions();
scan.AddAllTypesOf<IMessageHandlers>();
});
//x.For<IClient>().Use<Client>(); //GetInstance will work if this line is not commented out.
});
当我尝试获取实例时,我得到了错误,我获取实例的代码在这里:
chatInterface = container
.With("username").EqualTo(username)
.With("password").EqualTo(password)
.With("defaultRoomUrl").EqualTo(roomUrl)
.With<Action<object, object>>(delegate(object sender, object messageWrapper)
{
string message = ((dynamic)messageWrapper).Message;
Console.WriteLine("");
Console.WriteLine(message);
foreach (var item in messageHandlers)
{
item.MessageHandler.Invoke(message, chatInterface);
}
}).GetInstance<IClient>();
如果我将具体类显式映射到接口,一切正常,但这意味着我需要引用其中的项目,Client
我不想这样做。
