访问HTMLHelper类中的User.Identity.Name

Question

我正在写一个HTMLHelper,但我需要访问User.Identity.Name,我该怎么做？

Answer 1

public static string YourHtmlHelper(this HtmlHelper html)
{
    var name = html.ViewContext.HttpContext.User.Identity.Name;
}

Answer 2

您可能想要在尝试获取名称之前检查并查看User.Identity是否为空.

    public static string YourHtmlHelper(this HtmlHelper html) 
    { 
        var identity = html.ViewContext.HttpContext.User.Identity;

        if (identity != null)
        {
            return html.ViewContext.HttpContext.User.Identity.Name;
        }

        return string.Empty;
    }
