net core 的layout.cshtml文件有变化, 区分开发环境和非开发环境. 开发环境用的是非压缩的js和css, 正式环境用压缩的js和css
???<environment include="Development"> ???????<link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.css" /> ???????<link rel="stylesheet" href="~/css/site.css" /> ???</environment> ???<environment exclude="Development"> ???????<link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.7/css/bootstrap.min.css" ?????????????asp-fallback-href="~/lib/bootstrap/dist/css/bootstrap.min.css" ?????????????asp-fallback-test-class="sr-only" asp-fallback-test-property="position" asp-fallback-test-value="absolute" /> ???????<link rel="stylesheet" href="~/css/site.min.css" asp-append-version="true" /> ???</environment>
对view命名空间的引用,现在则改成了使用_ViewImport.cshtml文件，并且用razor语法来配置。
@using FoxCRMCore@using FoxCRMCore.Models@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
旧项目是把多语言放在资源文件里的. 但找了网上也没有详细讲Globalization的, 微软这篇文章讲的是Localization, 根本不好用.
https://docs.microsoft.com/en-us/aspnet/core/fundamentals/localization
所以我还是用扩展HtmlHelper的方法, 却出现一个错误: ‘IHtmlHelper<dynamic>‘ does not contain a definition for ‘Lang‘ and the best extension method overload ‘LocalizationHelper.Lang(HtmlHelper, string)‘ requires a receiver of type ‘HtmlHelper‘
找了好久才发现原因, https://stackoverflow.com/questions/30327764/how-to-create-an-extension-method-on-ihtmlhelperdynamic
现在Razor里的html扩展方法改成IHtmlHelper接口了.
using System;using Microsoft.AspNetCore.Mvc.Rendering;using Microsoft.AspNetCore.Mvc.ViewFeatures;namespace FoxCRMCore{ ???public static class LocalizationHelper ???{ ???????public static string Lang(this IHtmlHelper html, string key) ???????{ ???????????return Resources.Re.ResourceManager.GetString(key); ???????} ???}}把旧系统迁移到.Net Core 2.0 日记（5) ?Razor/HtmlHelper/资源文件
