内部类ASP.Net C＃ResolveClientUrl [英] ASP.Net C# ResolveClientUrl inside Class

问题描述

我有以下的code：

public class NavigationPath
{
    private string menuItems = "<li>" +
                                    "<a href=\"#\">home</a>" +
                               "</li>";

不过，我想有：

public class NavigationPath
{
    private string menuItems = "<li>" +
                                    "<a href=\"" + ResolveClientUrl("~/home.aspx") + "\">re</a>" +
                               "</li>";

不过，我不能够使用ResolveClientUrl一类中。任何ideias？

However, I am not able to use ResolveClientUrl inside a Class. Any ideias?

提前THX，对于u'r恬。

Thx in advance, for u'r tim.

推荐答案

ResolveClientUrl是System.Web.UI.Control类的成员，因此它直接访问为：

ResolveClientUrl is a member of the System.Web.UI.Control class, hence it's accessible directly as:

var url = ResolveClientUrl("~/Some/Url/");

当您的asp.net页面的code中调用。

when called within the code of your asp.net page.

要使用它你将不得不页面（或页面上的控件）传递到在其构造函数类的类中。即使如此，我不知道你能在你指定的方式来使用它。你可能不得不做类似的东西：

To use it inside a class you're going to have to pass the Page (or a control on the page) into the class in its constructor. Even then I'm not sure you'd be able to use it in the way you've indicated. You'd probably have to do something similar to:

public class NavigationPath
{
  private string menuItems = string.Empty;

  public NavigationPath(Page page)
  {
    menuItems = "<li>" + "<a href=\"" + page.ResolveClientUrl("~/Home.aspx") + "\">home</a>" + "</li>";
  }
}

和那么你的asp.net页面中做这样的事情：

And then inside your asp.net page do something like:

var navPath = new NavigationPage(this);
