Response.Write输出内容不在页面显示

Question

    protected void Page_Load(object sender, EventArgs e)
        {
            Ajax.Utility.RegisterTypeForAjax(typeof(AddOrderPrint));
            if (!Page.IsPostBack)
            {
              Response.Write("writing=success&");
            ｝
       ｝  页面最先输出这句话（FLASH接收这句传出值，相当于钥匙）
怎么不在页面上显示这句话？（输出在页面不美观）

Answer 1

将writing=success& 这个结果赋给一个变量， 前台引用该变量就可以。

Answer 2

protected string str = "";  
protected void Page_Load(object sender, EventArgs e)
        {
            Ajax.Utility.RegisterTypeForAjax(typeof(AddOrderPrint));
            if (!Page.IsPostBack)
            {
              str = "writing=success&";
            ｝
      ｝  
前台 <%=str%>

Answer 3

public string str = "";  
protected void Page_Load(object sender, EventArgs e) 
        {

            if (!Page.IsPostBack) 
            { 
              str = "writing=success&"; 
            ｝ 
      ｝  
前台 <%=str%>
