    //store requested language as new culture in the session
    if (senderLink.CommandArgument == "he-IL")

    else

    //reload last requested page with new culture

【解决方案1】：

在你的代码后面：

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签上并使用属性来填充它：

<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);

}

我尝试了您的建议，但对我不起作用。我会在后面贴一个代码。
@zZD1M0NZz - 在浏览器中查看源代码时会呈现什么？你有任何错误吗？例外？
不，没有错误或异常，也没有向body标签添加rtl属性
@zZD1M0NZz - 给定另一个选项。
抱歉，我不明白如何在点击事件中设置目录
