Nik*_*nis 1 c# reflection lambda fakeiteasy
是否可以通过Reflection编写以下代码?
var fake = A.Fake<Foo>(
o => o.WithArgumentsForConstructor(new[] { "Hello" }));

其中Ø为:
Action<IFakeOptionsBuilder<T>>

其中WithArgumentsForConstructor是:
IFakeOptionsBuilder<T> WithArgumentsForConstructor(IEnumerable<object> argumentsForConstructor);

Foo类是:
class Foo
{
public Foo(string s)
{
}
}

我做的是:
object fake = typeof(A)
.GetMethod("Fake", new Type[] { })
.MakeGenericMethod(new[] { this.targetType })
.Invoke(null, /* Here I need to pass the lambda. */);

是的,可以通过反思做你的建议,但是非常不必要.像这样自己定义一个静态方法会更简单:
public static class MyClass
{
public static T CreateFakeWithArgumentsForConstructor<T>(object[] argumentsForConstructor)
{
return A.Fake<T>(x => x.WithArgumentsForConstructor(argumentsForConstructor));
}
}

现在只需使用反射调用此函数:
var method = typeof(MyClass).GetMethod("CreateFakeWithArgumentsForConstructor", BindingFlags.Public | BindingFlags.Static).MakeGenericMethod(new[] { theType });
method.Invoke(null, argumentsForConstructor);
