ASP.NET Core 3.1 MVC中的本地化 [英] Localization in ASP.NET Core 3.1 MVC
本文介绍了ASP.NET Core 3.1 MVC中的本地化的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试将本地化添加到我的ASP.NET Core 3.1 MVC项目中，不幸的是，我找不到任何文章或教程来展示如何轻松地做到这一点.
每个人都有一些我无法理解的问题.
有人可以告诉我一种简单的方法吗?好的，我尝试做syncfusion.com/blogs/post/…但我遇到了一个问题(options.RequestCultureProviders = new [] {new RouteDataRequestCultureProvider {IndexOfCulture = 1，IndexofUICulture = 1}};)它说RequestCultureProviders没有没有IndexofUICulture ...
我已经达到这个水平:
<代码> @使用Microsoft.AspNetCore.Localization@using Microsoft.Extensions.Localization@using System.Resources@model索引@inject IStringLocalizer< Index>定位器@inject IHtmlLocalizer< Index>htmlLocalizer@ {ViewData ["Title"] ＝"M-POS"；//Microsoft.AspNetCore.Localization.IRequestCultureFeature requestCultureFeature;var requestCulture = CultureInfo.CurrentCulture;}< div class =文本中心">< h1 class ="display-4"> @localizer ["Welcome"]/h1< p> @localizer [学习"]/p<表类=表文化表">< tr>< td样式="宽度:50％;"文化</td>< td> @ requestCulture.DisplayName {@ requestCulture.Name}</td></tr>< tr>< td> UI文化</td>< td> @ requestCulture.Name</td></tr>< tr>< td> UICulture父</td>< td> @ requestCulture.Parent</td></tr>< tr>< td>日期</td>< td> @ DateTime.Now.ToLongDateString()</td></tr>< tr>< td>货币</td>< td>@(12345.00.ToString("c")))</td></tr>< tr>< td>货币</td>< td>@(12345.00.ToString("c")))</td></tr>< tr>< td>编号</td>< td>@(123.45m.ToString("F2")))</td></tr></table></div> ，然后在该文件夹中有一个名为Resources的文件夹，我有一个名为Resource.resx和Resource.en-US.resx的文件和StartUp.cs文件是这样的:

解决方案
问题1:与此相关的问题(options.RequestCultureProviders = new [] {new RouteDataRequestCultureProvider {IndexOfCulture = 1，IndexofUICulture = 1}};)它表示RequestCultureProviders没有IndexofUICulture ...

如何在ASP.NET Core Web API中使用本地化
I'm trying to add localization to my ASP.NET Core 3.1 MVC project, unfortunately I could not find any article or tutorial that shows how to do it in an easy way.
Each and everyone is having some issues that I could not understand.
Could anyone please show me an easy way to do this? ok, I tried to do syncfusion.com/blogs/post/… but I faced an issue with this (options.RequestCultureProviders = new[] { new RouteDataRequestCultureProvider { IndexOfCulture = 1, IndexofUICulture = 1 } };) it says that RequestCultureProviders doesn't have IndexofUICulture......
I have reached this level:
@using Microsoft.AspNetCore.Localization
@using Microsoft.Extensions.Localization
@using System.Resources
@model Index
@inject IStringLocalizer<Index> localizer
@inject IHtmlLocalizer<Index> htmlLocalizer
@{
ViewData["Title"] = "M-POS";
//Microsoft.AspNetCore.Localization.IRequestCultureFeature requestCultureFeature;
var requestCulture = CultureInfo.CurrentCulture;
}
<div class="text-center">
<h1 class="display-4">@localizer["Welcome"]</h1>
<p>@localizer["Learn"]</p>
<table class="table culture-table">
<tr>
<td style="width:50%;">Culture</td>
<td>@requestCulture.DisplayName {@requestCulture.Name}</td>
</tr>
<tr>
<td>UI Culture</td>
<td>@requestCulture.Name</td>
</tr>
<tr>
<td>UICulture Parent</td>
<td>@requestCulture.Parent</td>
</tr>
<tr>
<td>Date</td>
<td>@DateTime.Now.ToLongDateString()</td>
</tr>
<tr>
<td>Currency</td>
<td>
@(12345.00.ToString("c"))
</td>
</tr>
<tr>
<td>Currency</td>
<td>
@(12345.00.ToString("c"))
</td>
</tr>
<tr>
<td>Number</td>
<td>
@(123.45m.ToString("F2"))
</td>
</tr>
</table>
</div>
and then I have a folder called Resources inside that folder I have a file called Resource.resx and Resource.en-US.resx and the StartUp.cs file is like that:

}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
// The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
//configer localization
var localizationOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>().Value;
app.UseRequestLocalization(localizationOptions);
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
endpoints.MapRazorPages();
});
}
}
}
now I can't see resource.en-US.resx file values I think I'm missing something.
解决方案
Q1: an issue with this (options.RequestCultureProviders = new[] { new RouteDataRequestCultureProvider { IndexOfCulture = 1, IndexofUICulture = 1 } };) it says that RequestCultureProviders doesn't have IndexofUICulture......
Download the samples you will find RouteDataRequestCultureProvider.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Localization;
namespace LocalizationSampleSingleResxFile
{
public class RouteDataRequestCultureProvider : RequestCultureProvider
{
public int IndexOfCulture;
public int IndexofUICulture;
public override Task<ProviderCultureResult> DetermineProviderCultureResult(HttpContext httpContext)
{
if (httpContext == null)
throw new ArgumentNullException(nameof(httpContext));
string culture = null;
string uiCulture = null;
culture = uiCulture = httpContext.Request.Path.Value.Split('/')[IndexOfCulture]?.ToString();
var providerResultCulture = new ProviderCultureResult(culture, uiCulture);
return Task.FromResult(providerResultCulture);
}
}
}
Q2: Change name of your resource
You already named en-US, so your resource file name must format with en-US.
