Thanks,
推荐答案
<asp:contentplaceholder id="head" runat="server" >
</asp:contentplaceholder><!--Take note of id='head' -->
使用母版页的Web内容页必须使用与母版页文件中指定的占位符ID相同的内容元素.
Web content pages those which use the master page must use content elements which has the same placeholder id specified in Master Page File.
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<!--ContentPlaceHolderID="head" is important-->
</asp:Content>
在您的情况下，您使用的是ContentPlaceHolderID，而在这样的母版页中未指定.
In your case you are using a ContentPlaceHolderID which is not specified in master page like this.
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content> <!-- change ContentPlaceHolderID="HeadContent" to ContentPlaceHolderID="head" -->
这样可以修复错误.
希望对您有所帮助.
This will fix the error.
Hope it helps.
