这里两个ID="F" 的 runat="server" 不出错? --------------------编程问答-------------------- 去一个依旧不行。请问)(Control C in F.Controls)这里的F是哪的 --------------------编程问答-------------------- id="F" runat="server" 这里不是F吗? --------------------编程问答-------------------- 识别不了说是上下文不存在F --------------------编程问答--------------------
补充：.NET技术 , ASP.NET
