Umbraco中获取UmbracoContext

在Umbraco项目中，获取当前的UmbracoContext几乎是都需要用到的，我们一般通过一个静态方法来获取，代码如下

public class ContextHelpers
{

   public static UmbracoContext EnsureUmbracoContext()
   {

         if(UmbracoContext != null)
         {
             return UmbracoContext.Current;
         }

      var dummyHttpContext = new HttpContextWrapper(new HttpContext(new SimpleWorkerRequest("blah.aspx", "", new StringWriter())));
            return UmbracoContext.EnsureContext(
                dummyHttpContext,
                ApplicationContext.Current,
                new WebSecurity(dummyHttpContext, ApplicationContext.Current),
                UmbracoConfig.For.UmbracoSettings(),
                UrlProviderResolver.Current.Providers,
                false);

    }

}
