asp.net-mvc-3 – ASP.NET MVC 3： – 使用数据库而不是资源文件

欢迎提出意见/反馈.

编辑1：根据评论,我添加了代码示例并使用该链接作为参考.

我创建了一个customDataAnnotationsProvider类：

public class CustomDataAnnotationsProvider: DataAnnotationsModelMetadataProvider
{
    private ResourceManager resourceManager = new ResourceManager();
    protected override ModelMetadata CreateMetadata(
                         IEnumerable<Attribute> attributes,Type containerType,Func<object> modelAccessor,Type modelType,string propertyName)
    {
        string key = string.Empty;
        string localizedValue = string.Empty;


        foreach (var attr in attributes)
        {
            if (attr != null)
            {
                if (attr is DisplayAttribute)
                {
                    key = ((DisplayAttribute)attr).Name;
                    if (!string.IsNullOrEmpty(key))
                    {
                        localizedValue = resourceManager.GetLocalizedText(key);
                        ((DisplayAttribute)attr).Name = localizedValue;
                    }
                }
                else if (attr is ValidationAttribute)
                {
                    key = ((ValidationAttribute)attr).ErrorMessage;
                    if (!string.IsNullOrEmpty(key))
                    {
                        localizedValue = resourceManager.GetLocalizedText(key);
                        ((ValidationAttribute)attr).ErrorMessage = localizedValue;
                    }
                }
            }
        }
        return base.CreateMetadata(attributes,containerType,modelAccessor,modelType,propertyName);
    }
}

然后我在Global.asax中的ApplicationStart上引用了自定义提供程序

ModelMetadataProviders.Current = new Project.Web.Helpers.CustomDataAnnotationsProvider();

您不必更改模型,可以使用显示注释：

[Display(Name = "CustomerAccountNumber")]
public string CustomerAccountNumber { get; set; }
