路径中的非法字符.C#LoadControl

Question

我是C#的新手,正在使用sitecore开展项目

我刚刚添加了一个aspx页面

.aspx文件:

 <sc:sublayout runat="server" renderingid="{7ACDFB04-E9C9-4AC4-BDC6-6F3FF0862199}" path="/layouts/FSB/Header.ascx" id="HeaderFixed"></sc:sublayout>
    <sc:placeholder runat="server" key="layout" id="templatePage"></sc:placeholder>
    <sc:sublayout runat="server" renderingid="{621A56F6-9948-4661-9F33-3AFEF1DE698D}" path="/layouts/FSB/Footer.ascx" id="FooterFixed"></sc:sublayout> 

.cs文件

 Control templateControl = LoadControl("templateLandingPages/free_template.ascx");
 Control placeHolderControl = Page.FindControl("templatePage");

第16行的浏览器显示错误:

    Illegal characters in path.

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

    Exception Details: System.ArgumentException: Illegal characters in path.

Answer 1

关于你如何使用你的简单问题\.你需要加倍斜杠(\\).第一个充当第二个的转义字符.

Control templateControl = LoadControl("templateLandingPages\\free_template.ascx");

如评论,您还可以使用:

Control templateControl = LoadControl(@"templateLandingPages\free_template.ascx");
