InvalidOperationException: 在该类型中找到多个接受所有给定参数类型的构造函数

Question

在创建了第四个 ASP.NET Core 2.2 控制器后，我突然遇到了以下错误信息：

An unhandled exception occurred while processing the request.
InvalidOperationException: Multiple constructors accepting all given argument types have been found in type 'noblesbank.Controllers.AccountController'. There should only be one applicable constructor.
Microsoft.Extensions.DependencyInjection.ActivatorUtilities.TryFindMatchingConstructor(Type instanceType, Type[] argumentTypes, ref ConstructorInfo matchingConstructor, ref Nullable<int>[] parameterMap)

请问您能否提供AccountController的所有构造函数。 - KingOfArrows

我们需要查看控制器的实际代码。 - Jonathan Alfaro

Answer 1

在你想要在 DI 中使用的构造函数上使用 ActivatorUtilitiesConstructorAttribute。
