如何添加所有Razor页面都可以访问的功能? [英] How can I add a function that all Razor Pages can access?
问题描述
使用Razor页面ASP.Net Core,我想在每个页面上使用一些功能.我猜想这曾经是用App_Code完成的,但是似乎在Core中不再起作用了.如何在Asp.Net Core Razor Pages中完成此任务?
Using Razor Pages ASP.Net Core, I have some functions that I'd like to use on every page. I guess this used to be done with App_Code, but that no longer seems to work in Core. How can I accomplish this in Asp.Net Core Razor Pages?
推荐答案
选项1-
Option 1 - DI
1 - Create the service class with the relevant functionality
public class FullNameService
{
public string GetFullName(string first, string last)
{
return $"{first} {last}";
}
}
2-在启动时注册服务
2- Register the service in startup
services.AddTransient<FullNameService>();
3-将其注入到剃须刀页面
3- Inject it to the razor page
public class IndexModel : PageModel
{
private readonly FullNameService _service;
public IndexModel(FullNameService service)
{
_service = service;
}
public string OnGet(string name, string lastName)
{
return _service.GetFullName(name, lastName);
}
}
选项2-基本模型
1-使用功能创建基本页面模型
Option 2 - Base Model
1- Create a base page model with the function
public class BasePageModel : PageModel
{
public string GetFullName(string first, string lastName)
{
return $"{first} {lastName}";
}
}
2-从基本模型中导出其他页面
2- Derive other pages from the base model
public class IndexModel : BasePageModel
{
public string OnGet(string first, string lastName)
{
return GetFullName(first, lastName);
}
}
选项3-
Option 3 - Static Class
1- Use a static function that can be accessed from all pages
public static class FullNameBuilder
{
public static string GetFullName(string first, string lastName)
{
return $"{first} {lastName}";
}
}
2-从剃须刀页面调用静态功能
2- Call the static function from the razor page
public class IndexModel : PageModel
{
public string OnGet(string first, string lastName)
{
return FullNameBuilder.GetFullName(first, lastName);
}
}
选项4-扩展方法
1-为特定类型的对象(例如字符串)创建扩展方法
Option 4 - Extension Methods
1- Create an extension method for a specific type of objects (e.g. string)
public static class FullNameExtensions
{
public static string GetFullName(this string first, string lastName)
{
return $"{first} {lastName}";
}
}
2-从剃须刀页面拨打扩展名
2- Call the extension from razor page
public class IndexModel : PageModel
{
public string OnGet(string first, string lastName)
{
return first.GetFullName(lastName);
}
}
