FluentValidation“错误 cs0103 当前上下文中不存在名称‘x’”.asp.net 核心 2.1

Question

Issue

I am receiving the following error when using FluentValidation.AspNetCore (ver 8.6.1). this occurs when my edit view is saved. Very basic setup at the moment but i want to expand on the ActionValidator when it works...thanks

Error cs0103 the name 'x' does not exist in the current context

Code

Startup.cs -

    services.AddMvc()
        .SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
        .AddFluentValidation(fv => fv.RegisterValidatorsFromAssemblyContaining<ActionValidator>());

Validation class -

public class ActionValidator : AbstractValidator<EditActionVM>
{
    public ActionValidator()
    {
        RuleFor(x => x.ActionCompletionDate).NotEmpty();
    }
}

What i have tried

Following the FluentValidation guide at - https://docs.fluentvalidation.net/en/latest/aspnet.html#getting-started

Changing startup to use the following code -

    services.AddMvc()
        .SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
        .AddFluentValidation();

    services.AddTransient<IValidator<EditActionVM>, ActionValidator>();

Edit

EditActionVM.cs -

public class EditActionVM
{
    public int Id { get; set; }

    [Display(Name = "Action Reference")]
    public string ActionRef { get; set; }

    [Display(Name = "Status")]
    public Enums.Enums.Status Status { get; set; }

    [Display(Name = "Created Date")]
    public DateTime? CreatedDate { get; set; }

    [Display(Name = "Action Completion Date")]
    public DateTime? ActionCompletionDate { get; set; }

}

重新安装 FluentValidation 解决了我的问题......我的环境中可能有一些东西导致了这个问题
