在ABP中，本地化资源有两种类型：静态本地化资源和动态本地化资源。静态本地化资源是在应用程序开发期间添加的本地化字符串，它们被嵌入到程序集中。动态本地化资源是在应用程序运行时通过源添加的本地化字符串。

要扩展ABP中的本地化资源源，您可以遵循以下步骤：

1. 创建一个新的类，该类继承自 IApplicationLocalizationConfiguration 接口。

public class MyApplicationLocalizationConfiguration : IApplicationLocalizationConfiguration
{
    public List ExternalLocalizationSources { get; } = new List
    {
        typeof(MyCustomLocalizationDictionaryProvider)
    };
}

2. 创建一个新类 MyCustomLocalizationDictionaryProvider，该类继承自 ILocalizationDictionaryProvider 接口，并实现 GetDictionariesAsync 方法。

public class MyCustomLocalizationDictionaryProvider : ILocalizationDictionaryProvider
{
    private readonly IMyCustomLocalizationSource _myCustomLocalizationSource;

    public MyCustomLocalizationDictionaryProvider(IMyCustomLocalizationSource myCustomLocalizationSource)
    {
        _myCustomLocalizationSource = myCustomLocalizationSource;
    }

    public async Task> GetDictionariesAsync(
        GetLocalizationDictionariesInput input)
    {
        var dictionary = await _myCustomLocalizationSource.GetDictionaryAsync(input.CultureInfo);
        return new List
        {
            new LocalizationDictionary(dictionary)
        };
    }
}

3. 创建一个新类 MyCustomLocalizationSource，该类继承自 ILocalizationSource 接口，并实现 GetDictionaryAsync 方法。

public class MyCustomLocalizationSource : ILocalizationSource
{
    public string Name => "MyCustomLocalizationSource";

    public Task> GetDictionaryAsync(CultureInfo culture)
    {
        // add your custom dictionary here
        var dictionary = new Dictionary
        {
            {"Hello", "你好"},
            {"Goodbye", "
