Question

我有下课

public class Foo
{
  public Foo(int max=2000){...}
}

我希望使用Ninject为Foo注入一个常量值。我试过这个

Bind<Foo>().ToSelft().WithConstructorArgument("max", 1000);

但是当我尝试使用_ninject.Get<Foo>时出现以下错误：

Error activating int
No matching bindings are available, and the type is not self-bindable.
Activation path:
  3) Injection of dependency int into parameter max of constructor of type Foo

Answer 1

以下对我有用：

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Ninject;
using Ninject.Activation;
using Ninject.Syntax;


    public class Foo
    {
        public int TestProperty { get; set; }
        public Foo(int max = 2000)
        {
            TestProperty = max;
        }
    }

    public class Program
    {

        public static void Main(string [] arg)
        {
              using (IKernel kernel = new StandardKernel())
              {
                 kernel.Bind<Foo>().ToSelf().WithConstructorArgument("max", 1000);
                  var foo = kernel.Get<Foo>();
                  Console.WriteLine(foo.TestProperty); // 1000
              }

        }
    }

使用Ninject注入一个整数
