我正在最新版本的VS 2019中使用blazor 3.1。
到目前为止,我已经能够本地化页面标签(标题,表格字段等)。
在ListEmployee.razor
页上,我可以本地化表标题等。在AddEmplyeeValidation.razor
页上,我可以本地化表单标签,但是在本地化验证消息时遇到问题。
对于Employee.cs
文件的验证消息,验证消息在文件Resources/Data
和Data.Employee.resx
的{{1}}文件夹中定义,但这似乎不起作用。< / p>
Data.Employee.ar.resx
如何根据 using System.ComponentModel.DataAnnotations;
namespace BlazorSPA1.Data
{
public class Employee
{
[MaxLength(50)]
public string Id { get; set; }
[Required (ErrorMessage ="Name is RRRequired")]
[StringLength(20, ErrorMessage = "Name is too long.")]
public string Name { get; set; }
[Required]
[StringLength(20)]
public string Department { get; set; }
[MaxLength(100)]
public string Designation { get; set; }
[MaxLength(100)]
public string Company { get; set; }
[MaxLength(100)]
public string City { get; set; }
}
}
的语言从资源文件中加载验证消息?
AddEmployeForm
我已经阅读了几篇文章,并尝试了一些尝试,但似乎没有任何效果。
这是我的 @page "/addemployeeValidation"
@inject NavigationManager NavigationManager
@inject IEmployeeService EmployeeService
@inject IStringLocalizer<AddEmployeeValidation> L
<h2>Create Employee</h2>
<hr />
<EditForm Model="@employee" OnValidSubmit="@CreateEmployee">

我使用以下示例进行本地化,但是未显示如何本地化错误消息: https://www.c-sharpcorner.com/article/localization-in-blazor-server/

英语版本的资源文件示例,以同样的方式,我也有阿拉伯文件:
在下面的屏幕截图中,您将看到字段名称已从资源文件中正确提取,但是验证消息不起作用,仅以英文显示。

这是我的本地化数据注释错误消息的解决方案。我创建了两个资源文件,一个用于字段,另一个用于错误消息。
DisplayNameResource
用于本地化字段ErrorMessageResource
用于本地化错误消息在视图模型类中,使用Display
属性本地化字段名称。要指定资源文件,请使用ResourceType
属性上的Display
属性:
[Display(Name = "Address", ResourceType = typeof(DisplayNameResource))]
在验证属性上,使用ErrorMessageResourceName
和ErrorMessageResourceType
指定资源文件:
[Required(ErrorMessageResourceName = "RequiredError", ErrorMessageResourceType = typeof(ErrorMessageResource))]
以下是完整示例:
public class SomeViewModel
{
[Display(Name = "Address", ResourceType = typeof(DisplayNameResource))]
[Required(ErrorMessageResourceName = "RequiredError", ErrorMessageResourceType = typeof(ErrorMessageResource))]
[StringLength(256, ErrorMessageResourceName = "MaxLengthError", ErrorMessageResourceType = typeof(ErrorMessageResource))]
public string Address { get; set; }
[Display(Name = "Phone", ResourceType = typeof(DisplayNameResource))]
[Required(ErrorMessageResourceName = "RequiredError", ErrorMessageResourceType = typeof(ErrorMessageResource))]
[RegularExpression("^09([0-9]{9})$", ErrorMessageResourceName = "PhoneLengthError", ErrorMessageResourceType = typeof(ErrorMessageResource))]
public string Phone { get; set; }
[Display(Name = "Password", ResourceType = typeof(DisplayNameResource))]
[Required(ErrorMessageResourceName = "RequiredError", ErrorMessageResourceType = typeof(ErrorMessageResource))]
[StringLength(50, MinimumLength = 6, ErrorMessageResourceType = typeof(ErrorMessageResource), ErrorMessageResourceName = "MinxMaxLengthError")]
public string Password { get; set; }
[Display(Name = "ConfirmPassword", ResourceType = typeof(DisplayNameResource))]
[Required(ErrorMessageResourceName = "RequiredError", ErrorMessageResourceType = typeof(ErrorMessageResource))]
[StringLength(50, MinimumLength = 6, ErrorMessageResourceType = typeof(ErrorMessageResource), ErrorMessageResourceName = "MinxMaxLengthError")]
[Compare("Password", ErrorMessageResourceName = "PasswordConfirmMisMatch", ErrorMessageResourceType = typeof(ErrorMessageResource))]
public string ConfirmPassword { get; set; }
}
MaxLengthError
的错误消息是{0} cannot be longer than {1} character
,因此{0}
将被替换为本地化的文件名,{1}
将被替换为您在{属性256

此问题曾被问过:
How to add ViewModel localization to Blazor?
我建议使用FluentValidation是更好的方法。这是我的Github仓库的链接,展示了它如何工作:

我没有尝试过!
在asp.net core的官方文档中,有一节介绍如何本地化DataAnnotations
也许您找到了clues there。
