在ASP.Net MVC/Core中支持多种日期格式

[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public DateTime DateOfBirth { get; set; }

// Global.asax.cs
protected void Application_Start()
{
    // 设置默认的日期格式
    GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.DateFormatString = "yyyy-MM-dd";
}

// Startup.cs
public void ConfigureServices(IServiceCollection services)
{
    // 设置默认的日期格式
    services.AddMvc().AddJsonOptions(options =>
    {
        options.JsonSerializerOptions.Converters.Add(new DateTimeConverter("yyyy-MM-dd"));
    });
}

public class CustomDateTimeModelBinder : IModelBinder
{
    public Task BindModelAsync(ModelBindingContext bindingContext)
    {
        var valueProviderResult = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
        if (valueProviderResult == ValueProviderResult.None)
        {
            return Task.CompletedTask;
        }

        bindingContext.ModelState.SetModelValue(bindingContext.ModelName, valueProviderResult);

        var value = valueProviderResult.FirstValue;
        if (DateTime.TryParseExact(value, "yyyy-MM-dd", CultureInfo.InvariantCulture, DateTimeStyles.None, out var result))
        {
            bindingContext.Result = ModelBindingResult.Success(result);
        }
        else
        {
            bindingContext.ModelState.TryAddModelError(bindingContext.ModelName, "Invalid date format");
        }

        return Task.CompletedTask;

}

// Global.asax.cs
protected void Application_Start()

    // 注册自定义的模型绑定器
