我想创建一个自定义的剃刀视图基类（继承 WebViewPage ），将每个视图模板注入一些HTML渲染（包括布局和局部查看）让我有每个刀片模板开始在客户端（在它结束没兴趣）上的参考。

我已经试过到目前为止

重写Write方法（如在评论描述这里） 。这将给code在每个刀片部分，不只是一次按模板（每次使用的HTML.TextBoxFor时间例子） 重写ExecutePageHierarchy方法（如上述的链路的交描述）。这每一个它击中的第一个 PopContext 通话时抛出一个错误：的RenderBody的方法还没有被调用的页面布局〜/查看/共享/_Layout.cshtml。 解决方案

想我回答这个现在：

 公共抽象类CustomWebViewPage：WebViewPage
{
    公众覆盖无效ExecutePageHierarchy（）
    {
        VAR layoutReferenceMarkup = @＆LT;脚本类型=text / html的数据布局-ID =+ TemplateInfo.VirtualPath + @＆GT;＆LT; / SCRIPT＆gt;中;

        base.ExecutePageHierarchy（）;
        字符串输出= Output.ToString（）;

        //如果身体标记为present脚本标记应注入，否则只是追加
        如果（output.Contains（＆所述; /体＆gt;中））
        {
            Response.Clear（）;
            回复于（output.Replace（＆LT; /身体gt;中，layoutReferenceMarkup +＆LT; /身体GT;））;
            到Response.End（）;
        }
        其他
        {
            Output.Write（layoutReferenceMarkup）;
        }
    }
}

公共抽象类CustomWebViewPage＆LT; TModel的计算值：CustomWebViewPage
{
}
 

似乎工作，但如果任何人有一个更好的解决方案，请分享。

I'm trying to create a custom Razor view base class (inheriting WebViewPage) that will inject a bit of HTML for each view template being rendered (including Layouts and Partial Views) so that I have a reference on the client of where each Razor template starts (not interested in where it ends).

What I have tried so far is

overriding the Write method (as described in a comment here) . This injects code at every razor section, not just once per template (for example every time that you use the HTML.TextBoxFor) overriding the ExecutePageHierarchy method (as described in the post of the link above). This throws an error every time it hits the first PopContext call: The "RenderBody" method has not been called for layout page "~/Views/Shared/_Layout.cshtml".

解决方案

Think that I have an answer to this now:

public abstract class CustomWebViewPage: WebViewPage
{
    public override void ExecutePageHierarchy()
    {
        var layoutReferenceMarkup = @"<script type=""text/html"" data-layout-id=""" + TemplateInfo.VirtualPath + @"""></script>";

        base.ExecutePageHierarchy();
        string output = Output.ToString();

        //if the body tag is present the script tag should be injected into it, otherwise simply append
        if (output.Contains("</body>"))
        {
            Response.Clear();
            Response.Write(output.Replace("</body>", layoutReferenceMarkup+"</body>"));
            Response.End();
        }
        else
        {
            Output.Write(layoutReferenceMarkup);
        }
    }
}

public abstract class CustomWebViewPage<TModel>: CustomWebViewPage
{
}

Seems to work, but if anyone has a better solution, please share.
