如何在线程内生成ActionLink

您需要伪造HttpContextBase并将其传递给UrlHelper,您可以在没有HttpContext的线程中使用它。这里是一个粗略的想法,虽然您需要围绕它创建一个类,但是这是一个概念的快速证明,因为单元测试也没有HttpContext。

[TestFixture]
public class RouteTestClass
{
    private UrlHelper helper;

    public RouteTestClass()
    {
        MvcApplication.RegisterRoutes(RouteTable.Routes); //You dont need to do this if its done in global.asax!
        var c = new RequestContext(new FakeContext(), new RouteData());
        helper = new UrlHelper(c, RouteTable.Routes);
    }

    [Test]
    public void TestGetHomeIndex()
    {
        var url = helper.Action("Index", "Home");
        Assert.AreEqual("/",url);
    }
}

public class FakeContext : HttpContextBase
{
    public override HttpRequestBase Request { get { return new FakeRequest(); } }
    public override HttpResponseBase Response { get { return new FakeResponse(); } }
}

public class FakeRequest : HttpRequestBase
{
    public override string ApplicationPath { get { return "/"; } }
    public override NameValueCollection ServerVariables { get { return new NameValueCollection(); } }
}

public class FakeResponse : HttpResponseBase
{
    public override string ApplyAppPathModifier(string virtualPath)
    {
        return virtualPath;
    }
}

[TestFixture]
public class RouteTestClass
{
    private UrlHelper helper;

    public RouteTestClass()
    {
        MvcApplication.RegisterRoutes(RouteTable.Routes);
        var req = new HttpRequest("/", "http://www.yoururl.com", "");
        var resp = new HttpResponse(new StringWriter());
        var httpContext = new HttpContext(req, resp);
        var c = new RequestContext(new HttpContextWrapper(httpContext), new RouteData());
        helper = new UrlHelper(c, RouteTable.Routes);
    }

    [Test]
    public void TestGetHomeIndex()
    {
        var url = helper.Action("Index", "Home");
        Assert.AreEqual("/",url);
    }
}

您可以授予线程对现有 UrlHelper URL帮助程序 Url 属性:

new Thread(
    urlHelper =>
    {
        var url = 
            ((UrlHelper)urlHelper)
            .Action("Index", "Home", new { Id = 5 });
        // use url here
    }
).Start(Url);
