C# 在.net Core 3.1中将ActionFilterAttribute解析为TypeFilter时出错

将我的应用程序从.Net Core 2.2更新到3.1时，我在尝试解决ActionFilter的依赖关系时出错

我有这个过滤器

public class DoSomethingAttribute : ActionFilterAttribute
    {
        private readonly IWorkContext workContext;

        public OneEnum OneParameter { get; set; }

        public AuthorizeAdminAttribute(OneEnum oneParameter, IWorkContext workContext)
        {
            OneParameter = oneParameter;
            workContext = workContext;
        }

         /**more stuff**/
    }

我登记了

services.AddScoped<DoSomethingAttribute>();

有什么想法吗？

下面是一个工作演示，如下所示：

public class MyFilterAttribute : TypeFilterAttribute
{
    public MyFilterAttribute(params object[] arguments) : base(typeof(DoSomethingAttribute))
    {
        Arguments = new object[] { arguments };
    }

    public class DoSomethingAttribute : ActionFilterAttribute
    {

        private readonly IWorkContext WorkContext;
        private readonly OneEnum OneParameter;
 
        public DoSomethingAttribute(object[] arguments, IWorkContext workContext)
        {
            OneParameter = (OneEnum)arguments[0];
            WorkContext = workContext;

        }

        public override async Task OnActionExecutionAsync(ActionExecutingContext context, ActionExecutionDelegate next)
        {
            //do your stuff....
             await base.OnActionExecutionAsync(context, next);
        }
    }
}

services.AddScoped<DoSomethingAttribute>();

将属性添加到控制器：

[MyFilter(OneEnum.OneValue)]
public async Task<IActionResult> Delete(int id)
{}

[MyFilter（OneEnum.OneValue）]
公共异步任务删除（int-id）
{}

无需注册如下属性：

public class MyFilterAttribute : TypeFilterAttribute
{
    public MyFilterAttribute(params object[] arguments) : base(typeof(DoSomethingAttribute))
    {
        Arguments = new object[] { arguments };
    }

    public class DoSomethingAttribute : ActionFilterAttribute
    {

        private readonly IWorkContext WorkContext;
        private readonly OneEnum OneParameter;
 
        public DoSomethingAttribute(object[] arguments, IWorkContext workContext)
        {
            OneParameter = (OneEnum)arguments[0];
            WorkContext = workContext;

        }

        public override async Task OnActionExecutionAsync(ActionExecutingContext context, ActionExecutionDelegate next)
        {
            //do your stuff....
             await base.OnActionExecutionAsync(context, next);
        }
    }
}

services.AddScoped<DoSomethingAttribute>();

services.addScope（）；

只要删除服务。AddScoped（）这一行，您就会看到错误消失，IWorkContext将由asp.net core自动注入。谢谢@Changemyminds，这就是解决方案谢谢。我删除了注册并且成功了。如果我的解决方案对您有所帮助，您能接受我的回答吗？
