我创建了数据合同,如下所示: -

[DataContract(Name = "Animal")]
public class Animal { ... }

[DataContract(Name = "Dog ")]
public class Dog : Animal { // Has some Dog specific member properties }

[DataContract(Name = "Cat ")]
public class Cat : Animal { // Has some Cat specific member properties }

我正在使用ASP.NET WebApi来提供REST API,如:

[HttpGet]
public Task<Animal> Get(string type) 
{ 
    switch(type)
    {
        case "dog":
            Dog dog = GetDogDetails();
            return Task.FromResult(dog);
            break;

        case "cat":
            Cat cat = GetCatDetails();
            return Task.FromResult(cat);
            break:
    }
}

我无法归还各自的动物类型.我收到以下错误: - …

使用NSubstitute,如何模拟返回void的方法中抛出的异常？

假设我们的方法签名看起来像这样:

    void Add();

以下是NSubstitute文档如何模拟抛出void返回类型的异常.但这不编译:(

    myService
        .When(x => x.Add(-2, -2))
        .Do(x => { throw new Exception(); });

那你怎么做到这一点？
