定義

命名空間:

判斷參數值是否符合該參數的條件約束。

protected:
 virtual bool ProcessConstraint(System::Web::HttpContextBase ^ httpContext, System::Object ^ constraint, System::String ^ parameterName, System::Web::Routing::RouteValueDictionary ^ values, System::Web::Routing::RouteDirection routeDirection);

protected virtual bool ProcessConstraint (System.Web.HttpContextBase httpContext, object constraint, string parameterName, System.Web.Routing.RouteValueDictionary values, System.Web.Routing.RouteDirection routeDirection);

abstract member ProcessConstraint : System.Web.HttpContextBase * obj * string * System.Web.Routing.RouteValueDictionary * System.Web.Routing.RouteDirection -> bool
override this.ProcessConstraint : System.Web.HttpContextBase * obj * string * System.Web.Routing.RouteValueDictionary * System.Web.Routing.RouteDirection -> bool

Protected Overridable Function ProcessConstraint (httpContext As HttpContextBase, constraint As Object, parameterName As String, values As RouteValueDictionary, routeDirection As RouteDirection) As Boolean

參數

httpContext

HttpContextBase

封裝 HTTP 要求相關資訊的物件。

constraint

Object

規則運算式或要用來測試 parameterName 的物件。

parameterName

String

要測試的參數名稱。

values

RouteValueDictionary

routeDirection

RouteDirection

指定 URL 路由是在處理傳入的要求還是在建構 URL 的值。
