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

问题描述

我有以下功能，我希望可以在我的 asp.net 网页 2 应用程序中使用多个 .cshtml 视图.如何使该功能可用于应用程序中的任何视图(而不是只有一个).

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.然后你可以在任何 .cshtml 文件中调用 DisplayButton 方法，方法是在文件名前加上前缀:

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));
