在母版页'/WebSite2/Site.master'中找不到ContentPlaceHolder'HeadContent'，验证内容控件的内容页面中的ContentPlaceHolderID属性。
Cannot find ContentPlaceHolder 'HeadContent' in the master page '/WebSite2/Site.master', verify content control's ContentPlaceHolderID attribute in the content page.
这意味着您拥有属性 ContentPlaceHolderID 的控件为 HeadContent ，但不幸的是它不在母版页。
所以，要么使用正确的 ContentPlaceHolderID ，位于母版页或只是重命名ContentPlaceHolderID
That means you have control which have the property ContentPlaceHolderID as HeadContent, but unfortunately it is not in the Master Page.
So, either use correct ContentPlaceHolderID, which is in Master Page or just rename the ContentPlaceHolderID
