一个与ASP.net MVC路线多值路径参数约束

Question

我的路线：

routes.MapRoute(
     name: "Without Controller", 
     url: "{id}", 
     defaults: new { controller = "myControler", action = "Index", id = UrlParameter.Optional }, 
     constraints: new { id = new NotEqual("Home")}); 

定制路线：

public class NotEqual : IRouteConstraint 
    { 
     private readonly string _match = String.Empty; 

     public NotEqual(string match) 
     { 
      _match = match; 
     } 

     public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) 
     { 
      return String.Compare(values[parameterName].ToString(), _match, System.StringComparison.OrdinalIgnoreCase) != 0; 
     } 

    } 

问：我需要筛选既“首页“和”登录“ids.How can I do it？任何帮助将不胜感激。

constraints: new { id = new NotEqual("Home")});//I need to give "Login" also ? 

Answer 1

正如我的意见建议，这样的事情：

public class NotEqual : IRouteConstraint 
{ 
    private readonly List<string> _matches; 

    public NotEqual(string matches) 
    { 
     _matches = matches.Split(',').ToList(); 
    } 

    public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) 
    { 
     return !_matches.Contains(values[parameterName].ToString()); 
    } 

} 

然后：

constraints: new { id = new NotEqual("Home,Login")}); 

Answer 2

您可以使用PARAMS

public NotEqual(params string[] matches) 
{ 
    _match = match.Join(",", matches); 
} 

Answer 3

public class NotEqual : IRouteConstraint 
    { 
     string[] _matches; 

     public NotEqual(string[] matches) 
     { 
      _matches = matches; 
     } 

     public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) 
     { 
      return !_matches.Any(m => string.Equals(m, values[parameterName].ToString(), StringComparison.InvariantCultureIgnoreCase)); 
     } 
    } 

然后在您的路线配置：

constraints: new { id = new NotEqual(new string[] { "Home", "Login" })});
