This project provides localized validation messages and exception prompts for the .NET System.ComponentModel.Annotations library.
When using ValidationAttribute for model validation, if you want to provide users with localized error messages instead of the default English messages, you would have to specify the ErrorMessage parameter. This can be cumbersome if you have a large number of models to validate. By adding localized language resources, we can obtain localized messages without specifying ErrorMessage.
- Multilingual Support: Provides localization resources for multiple languages, with support for Simplified Chinese and Traditional Chinese already available.
- Continuous Updates: Localization resources will be updated in sync with .NET versions to ensure compatibility and accuracy.
- Community-Driven: Developers are welcome to contribute translations to help improve localization support.
Install the appropriate NuGet package based on the version of .NET you are using and the localization language you need.
For example:
Install-Package FxResources.System.ComponentModel.Annotations.zh-Hans -Version 8.0.0
If you are not using internationalization features and just want to provide localized model validation messages to users, you need to set the default UI culture.
// program.cs
CultureInfo.DefaultThreadCurrentUICulture = CultureInfo.GetCultureInfo("zh-Hans");If you are using ASP.NET Core's internationalization features, you only need to add the culture you are using to the supported list. You should have already done this under normal circumstances.
services.AddRequestLocalization(t =>
{
t.AddSupportedUICultures("zh-CN", "zh-TW", "en");
});
You no longer need to specify ErrorMessage on validation attributes.
public class FooUser
{
[Required]
public string Name { get; set; }
[Required]
public string Email { get; set; }
[Required]
[Range(1, 100)]
public int? Age { get; set; }
}Assuming no parameters are passed, you will get the following error messages:
Age字段为必填项。
Name字段为必填项。
Email字段为必填项。
- Translation Contribution: Choose a language and submit the translated localization resources.
- Report Issues: Report translation errors or missing language support in the Issues section.
Welcome to join us and provide localization support for more cultures!
SR.resx: Contains the neutral language resource file, which is identical to the official original resources.SR.{culture}.resx: Contains localized resource files for the corresponding culture.
Note: The content of SR.resx may vary slightly between different versions of .NET, so please make sure you are using the correct version or branch.
