C#-Ninject：激活字符串时出错

我正在遵循有关如何设置SQLite的指南.在指南中,他使用如下代码：

public MainPage()
{
     InitializeComponent();

     // Setup database
     var path = Path.Combine(Path.Combine(ApplicationData.Current.LocalFolder.Path, "test.sqlite"));
     _connection = new SQLiteConnection(new SQLitePlatformWP8(), path); 
}

我试图做同样的事情,但遵循MVVM.
我以为他是要走的路：

public override void Load()
{
    var path = Path.Combine(Path.Combine(ApplicationData.Current.LocalFolder.Path, "test.sqlite"));

    Bind<ISQLitePlatform>().To<SQLitePlatformWP8>().WithConstructorArgument("test.sqlite", path);
}

Ninject回应：

No matching bindings are available, and the type is not self-bindable.

Activation path:

  4) Injection of dependency string into parameter databasePath of constructor

  3) Injection of dependency SQLiteConnection into parameter connection of constructor

  2) Injection of dependency ICarRepository into parameter carRepository of constructor

  1) Request for MainVModel

关于如何解决这一问题的任何提示？

解决方法:

SQLiteConnection需要参数,而不需要SQLitePlatformWP8.

因此,将您的注册更改为：

Bind<SQLiteConnection>.ToSelf().WithConstructorArgument("databasePath", path);
Bind<ISQLitePlatform>().To<SQLitePlatformWP8>();

注意：您需要使用正确的参数名称“ databasePath”,该名称在SQLiteConnection类的constructor中定义.
