Tanım

UrlMapping sınıfının yeni bir örneğini başlatır.

public:
 UrlMapping(System::String ^ url, System::String ^ mappedUrl);
public UrlMapping (string url, string mappedUrl);
new System.Web.Configuration.UrlMapping : string * string -> System.Web.Configuration.UrlMapping
Public Sub New (url As String, mappedUrl As String)

Parametreler

url
String

Kullanıcıya görüntülenecek URL.

mappedUrl
String

Web uygulamanızda bulunan bir URL.

Açıklamalar

Oluşturucu UrlMapping öncelikle ASP.NET tarafından iç kullanıma yöneliktir. Bu sınıftan türetmeniz gerekmez ve Web.config dosyasını değiştirmek için kullanılabildiğinden, büyük olasılıkla kodda kullanmanıza gerek yoktur.
