Question

在Page_Load事件处理函数中，我尝试了以下内容：

protected void Page_Load(object sender, EventArgs e)
    {
        if (Context.User.Identity.IsAuthenticated)
        {
            Response.Write("Hello World");
        }
    }

它有效！浏览器显示Hello World！但默认情况下IsAuthenticated属性如何获得真值？

我的web.config文件如下：

<?xml version="1.0"?>

Answer 1

这取决于<authentication />元素的模式属性;如果是Windows，它将被设置为true，因为它使用当前的Windows用户;如果是表格，那么你必须登录。

Answer 2

添加以下内容：

<authentication mode="Windows"/>

<system.web>部分内的某个地方，如下所示：

<configuration>
    <system.web>
        <authentication mode="Windows"/>
    <system.web>
</configuration>

更新您的示例：

<?xml version="1.0"?>

`IsAuthenticated`属性默认如何获得真值？
