MVC在网页中引用js脚本，下面两种格式的效果是一样的吗？一样的有什么区别？
--------------------编程问答----------------------------------------编程问答--------------------
public string Content(string contentPath) {
return Content(contentPath, RequestContext.HttpContext);
}
internal static string Content(string contentPath, HttpContextBase httpContext) {
if (String.IsNullOrEmpty(contentPath)) {
throw new ArgumentException(MvcResources.Common_NullOrEmpty, "contentPath");
}
if (contentPath[0] == '~') {
return PathHelpers.GenerateClientUrl(httpContext, contentPath);
}
else {
return contentPath;

// this method can accept an app-relative path or an absolute path for contentPath--------------------编程问答--------------------
public static string GenerateClientUrl(HttpContextBase httpContext, string contentPath) {
if (String.IsNullOrEmpty(contentPath)) {
return contentPath;
}
// many of the methods we call internally can't handle query strings properly, so just strip it out for
// the time being
string query;
contentPath = StripQuery(contentPath, out query);
return GenerateClientUrlInternal(httpContext, contentPath) + query;
}
private static string GenerateClientUrlInternal(HttpContextBase httpContext, string contentPath) {
if (String.IsNullOrEmpty(contentPath)) {
return contentPath;
}
// can't call VirtualPathUtility.IsAppRelative since it throws on some inputs
bool isAppRelative = contentPath[0] == '~';
if (isAppRelative) {
string absoluteContentPath = VirtualPathUtility.ToAbsolute(contentPath, httpContext.Request.ApplicationPath);
string modifiedAbsoluteContentPath = httpContext.Response.ApplyAppPathModifier(absoluteContentPath);
return GenerateClientUrlInternal(httpContext, modifiedAbsoluteContentPath);
}
// we only want to manipulate the path if URL rewriting is active, else we risk breaking the generated URL
NameValueCollection serverVars = httpContext.Request.ServerVariables;
bool urlRewriterIsEnabled = (serverVars != null && serverVars[_urlRewriterServerVar] != null);
if (!urlRewriterIsEnabled) {
return contentPath;
}
// Since the rawUrl represents what the user sees in his browser, it is what we want to use as the base
// of our absolute paths. For example, consider mysite.example.com/foo, which is internally
// rewritten to content.example.com/mysite/foo. When we want to generate a link to ~/bar, we want to
// base it from / instead of /foo, otherwise the user ends up seeing mysite.example.com/foo/bar,
// which is incorrect.
string relativeUrlToDestination = MakeRelative(httpContext.Request.Path, contentPath);
string absoluteUrlToDestination = MakeAbsolute(httpContext.Request.RawUrl, relativeUrlToDestination);

}
直接写第二个得了 第一个得多做很多事吧
--------------------编程问答--------------------
请问能说一下两者的区别吗 --------------------编程问答-------------------- UrlHelper.Content:将虚拟（相对）路径转换为应用程序绝对路径。 --------------------编程问答-------------------- MVC4/Razor2.0 里面用第二种就好了 微软的东西有时候就这样让人很蛋疼 新瓶装旧酒 --------------------编程问答-------------------- 要是网站放在虚拟目录下可能会有问题 --------------------编程问答-------------------- 第一种没问题，但是没有智能提示 哎 --------------------编程问答--------------------
第二种使用的虚拟路径，会有什么问题呢？ --------------------编程问答--------------------
有时候你的网站放在二级目录下的时候 有可能找不到实际的js文件
补充：.NET技术 , ASP.NET
