asp.net - ASP.NET 虚拟路径在哪里解析波浪号 "~"？

Question

ASP.NET虚拟路径在哪里解析链接中的波形符~，例如

<link rel="stylesheet" type="text/css" href="~/Css/Site.css" />

它是重定向，还是 ASP.NET MVC 中的 RedirectToAction ？

Answer 1

它从这里获取:

VirtualPathUtility.ToAbsolute(contentPath, httpContext.Request.ApplicationPath);

以下是 System.Web.Mvc DLL 中 PathHelpers 类的反射器输出:

private static string GenerateClientUrlInternal(HttpContextBase httpContext, string contentPath)
{
    if (string.IsNullOrEmpty(contentPath))
    {
        return contentPath;
    }
    if (contentPath[0] == '~')
    {
        string virtualPath = VirtualPathUtility.ToAbsolute(contentPath, httpContext.Request.ApplicationPath);
        string str2 = httpContext.Response.ApplyAppPathModifier(virtualPath);
        return GenerateClientUrlInternal(httpContext, str2);
    }
    NameValueCollection serverVariables = httpContext.Request.ServerVariables;
    if ((serverVariables == null) || (serverVariables["HTTP_X_ORIGINAL_URL"] == null))
    {
        return contentPath;
    }
    string relativePath = MakeRelative(httpContext.Request.Path, contentPath);
    return MakeAbsolute(httpContext.Request.RawUrl, relativePath);
}
