如何将asp-validation-for连接到我的新错误

<input type="text" id="email" name="email" asp-validation-for="email" />
<span asp-validation-summary="ModelOnly" class="text-danger"></span>

public class YourModel
{
    [Required(ErrorMessage = "Email is required")]
    [EmailAddress(ErrorMessage = "Invalid email address")]
    public string Email { get; set; }
}

[HttpPost]
public IActionResult YourAction(YourModel model)
{
    if (!ModelState.IsValid)
    {
        return View(model);
    }

    // 处理表单提交的逻辑

    return RedirectToAction("Success");
}

<span asp-validation-for="email" class="text-danger"></span>
