如何在 C Sharp 中以编程方式将 HTML 标记目录属性从 RTL 设置为 LTR，反之亦然

在你的代码隐藏中：

this.html.Attributes.Add("dir", "ltr");

如果这不起作用，另一种方法是将属性直接放在标记上并使用属性填充它：

<body dir="<%:Dir%>">
public string Dir { get; set; }
// Set Dir in the on click event
protected void RequestLanguageChange_Click(object sender, EventArgs e)
{
    LinkButton senderLink = sender as LinkButton;
    //store requested language as new culture in the session
    if (senderLink.CommandArgument == "he-IL")
    {
        Dir = "rtl";
    }
    else
    {
        Dir = "ltr";
    }
    Session[Global.SESSION_KEY_CULTURE] = senderLink.CommandArgument;
    //reload last requested page with new culture
    Server.Transfer(Request.Path);
}
