我正在爲MVC Web應用程序中的HtmlHelper類創建擴展方法。什麼都沒有顯示,甚至沒有默認的InputExtensions。擴展方法未顯示
public static class HtmlHelpers
{
public static void RegisterScriptInclude(this HtmlHelper htmlhelper, string script)
{
if (!RegisteredScriptIncludes.ContainsValue(script))
{
RegisteredScriptIncludes.Add(RegisteredScriptIncludes.Count, script);
}
}
public static string RenderScripts(this HtmlHelper htmlhelper)
{
var scripts = new StringBuilder();
foreach (string script in RegisteredScriptIncludes.Values)
{
scripts.AppendLine("<script src='" + script + "' type='text/javascript'></script>");
}
return scripts.ToString();
}
private static SortedList<int, string> RegisteredScriptIncludes
{
get
{
SortedList<int, string> value = (SortedList<int, string>)HttpContext.Current.Items["RegisteredScriptIncludes"];
if (value == null)
{
value = new SortedList<int, string>();
HttpContext.Current.Items["RegisteredScriptIncludes"] = value;
}
return value;
}
}
}
擴展方法沒有顯示在代碼中。
他們在哪裏?
