c# - CaSTLe Windsor 注册类带有构造函数参数

Question

我有以下类(class):

public class DatabaseFactory<C> : Disposable, IDatabaseFactory<C> where C : DbContext, BaseContext, new()
{
    private C dataContext;
    private string connectionString;

    public DatabaseFactory(string connectionString)
    {
        this.connectionString = connectionString;
    }

    public C Get()
    {
        return dataContext ?? (dataContext = Activator.CreateInstance(typeof(C), new object[] {connectionString}) as C);
    }

    protected override void DisposeCore()
    {
        if (dataContext != null)
            dataContext.Dispose();
    }
}

当我尝试启动 web api 时，出现以下错误:

无法创建组件 'MyApp.DAL.Implementations.DatabaseFactory'1'，因为它需要满足依赖关系。 'MyApp.DAL.Implementations.DatabaseFactory'1' 正在等待以下依赖项: - 未提供的参数“connectionString”。是不是忘记设置依赖了？

如何正确注册，如何在运行时传递参数？

Answer 1

需要注册构造函数参数:

container.Register(
    Component.For<IDatabaseFactory>().ImplementedBy<DatabaseFactory>()
             .DependsOn(Dependency.OnValue("connectionString", connectionString))
    );
