C# 使用数据注释部分验证模型属性
我使用数据注释对模型属性设置了两个验证,如下所示:C# 使用数据注释部分验证模型属性,c#,asp.net-mvc,data-annotations,C#,Asp.net Mvc,Data Annotations,我使用数据注释对模型属性设置了两个验证,如下所示: [MinLength(8, ErrorMessage = "Password Requires at least one letter, one number and 8 characters long")] [Required(ErrorMessage = "Password Required")] public string Password { get; set; } 我想在一些特殊情况下进行部分验证。例如,我不想在用户登录时检查
[MinLength(8, ErrorMessage = "Password Requires at least one letter, one number and 8 characters long")]
[Required(ErrorMessage = "Password Required")]
public string Password { get; set; }
我想在一些特殊情况下进行部分验证。例如,我不想在用户登录时检查最小长度,但只在注册时检查
任何人都知道如何实现这一点吗?使用不同的视图模型进行注册和登录,就像默认的asp.net-mvc实现一样 您将得到3个类:模型本身、登录类和注册类。具有密码长度验证的唯一类应该是模型本身,而不是视图模型。然后,使用控制器,您应该从ViewModel填充到模型(当执行POST时)或从模型填充到ViewModel(当执行GET时) 登录视图模型示例(取自默认MVC代码) 和注册ViewModel,也来自默认MVC
public class RegisterViewModel
{
[Required]
[EmailAddress]
[Display(Name = "Email")]
public string Email { get; set; }
[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }
}
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);
// For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
// Send an email with this link
// string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
// var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
// await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");
return RedirectToAction("Index", "Home");
}
AddErrors(result);
}
// If we got this far, something failed, redisplay form
return View(model);
}
注册ViewModel和模型本身的使用示例,所有默认MVC
public class RegisterViewModel
{
[Required]
[EmailAddress]
[Display(Name = "Email")]
public string Email { get; set; }
[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }
}
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model)
{
if (ModelState.IsValid)
{
var user = new ApplicationUser { UserName = model.Email, Email = model.Email };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);
// For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
// Send an email with this link
// string code = await UserManager.GenerateEmailConfirmationTokenAsync(user.Id);
// var callbackUrl = Url.Action("ConfirmEmail", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
// await UserManager.SendEmailAsync(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=\"" + callbackUrl + "\">here</a>");
return RedirectToAction("Index", "Home");
}
AddErrors(result);
}
// If we got this far, something failed, redisplay form
return View(model);
}
[HttpPost]
[异名]
[ValidateAntiForgeryToken]
公共异步任务);
返回重定向到操作(“索引”、“主页”);
}
加法器(结果);
}
//如果我们走到这一步,有些东西失败了,重新显示形式
返回视图(模型);
}
然后使用两种视图模型,一种用于登录,另一种用于注册(由于注册视图应具有“确认密码”字段,因此它们应该有所不同),请查看FluentValidation以解决您的问题
