在多个网页中使用Razor @functions(.cshtml文件) [英] Using a Razor @functions in several webpages (.cshtml files)

问题描述

我有以下功能，希望对我的asp.net网页2应用程序中的多个.cshtml视图可用.如何使此功能可用于应用程序中的任何视图(而不是一个视图).

I have the below function that I would like to be available to several .cshtml views in my asp.net web pages 2 application. How can I make this function available to any view in the application (as opposed to just one).

@functions {

    public bool DisplayButton(String startDate, String endDate)
    {
        return Convert.ToDateTime(startDate) < DateTime.Now && Convert.ToDateTime(endDate) > DateTime.Now;
    }
}

推荐答案

在App_Code中创建一个名为Functions.cshtml的文件，然后将您拥有的代码粘贴到该文件中.然后，您可以通过在任何.cshtml文件中添加文件名作为前缀来调用DisplayButton方法:

Create a file called Functions.cshtml in App_Code and then paste the code you have into the file. Then you can call the DisplayButton method in any .cshtml file by prefixing it with the file name:

var myBool = Functions.DisplayButton(DateTime.Now, DateTime.Now.AddDays(30));
