C# ASP.NET 获取脚本语句并用文本的方式显示出来

protected void Button6_Click(object sender, EventArgs e)
    {
        this.Label11.Text = HtmlEncode(this.TextBox3.Text);
 
       
    }
    protected static string HtmlEncode(string the)
    {
   
        the = the.Replace("<", "&lt;");
        the = the.Replace(" ", "&nbsp;");
        the = the.Replace("\"", "&quot;");
        the = the.Replace("\'", "'");
        the = the.Replace("\n", "<br/> ");
        return the;
    }
通过在 Page 指令或 配置节中设置 validateRequest=false
就是在页面中加入
<%@page validateRequest=false %>
