asp.net-mvc – 更改ASP.NET MVC 3中的默认ModelState错误消息

我将资源文件放在单独的程序集MyApp.Resources.dll中.我可以毫无问题地使用资源,但是当我想更改(本地化)默认验证消息时会出现问题：

“{0}字段是必需的.”和“值'{0}’对{1}无效.”

solution DefaultModelBinder.ResourceClassKey =“MyApp.Resources.Global”;不起作用,因为它要求ResourceClassKey位于Web项目中的App_GlobalResources文件夹下.

应该为我解决什么？

解决方法

我找到了这种情况的解决方案(当资源处于单独的程序集中时).

为了使它工作,您应该创建自定义ResourceProviderFactory并将其注册为< globalization>中的默认ResourceProviderFactoryType. web.config部分.

设置本地化

// Modify web.config in run-time and setup custom ResourceProviderFactory
var globalization = WebConfigurationManager.GetSection("system.web/globalization") as GlobalizationSection;
var readonlyField = typeof(ConfigurationElement).GetField("_bReadOnly",BindingFlags.Instance | BindingFlags.NonPublic);
readonlyField.SetValue(globalization,false);
globalization.ResourceProviderFactoryType = typeof(ValidationResourceProviderFactory).FullName;

var resourcesClass = typeof(ValidationResources).FullName; 
DefaultModelBinder.ResourceClassKey = resourcesClass;
ValidationExtensions.ResourceClassKey = resourcesClass;

ValidationResourceProviderFactory

public sealed class ValidationResourceProviderFactory: System.Web.Compilation.ResourceProviderFactory
{
    public ValidationResourceProviderFactory()
    {
    }

    public override IResourceProvider CreateGlobalResourceProvider(string classKey)
    {
        return new GlobalResourceProvider(classKey);
    }

    public override IResourceProvider CreateLocalResourceProvider(string virtualPath)
    {
        throw new NotImplementedException("Local resources are not supported yet");
    }
}

GlobalResourceProvider

public class GlobalResourceProvider : IResourceProvider
{
    public GlobalResourceProvider(string classKey)
    {
        Throw.IfBadArgument(() => String.IsNullOrEmpty(classKey),"classKey");

        var type = Type.GetType(classKey,false);
        if (type == null)
        {
            var asmName = classKey;
            var className = classKey;
            while(asmName.IndexOf(".") > -1 && type == null) 
            {
                asmName = asmName.Substring (0,asmName.LastIndexOf("."));
                className = classKey.Substring(asmName.Length + 1);
                type = Type.GetType(classKey + "," + asmName,false);
            }
        }

        Throw.IfNullArgument(type,"type");

        Manager = CreateResourceManager(classKey,type.Assembly);
    }

    public ResourceManager Manager { get; set; }

    #region IResourceProvider implementation

    public IResourceReader ResourceReader { get; set; }

    public object GetObject(string resourceKey,CultureInfo culture)
    {
        return Manager.GetObject(resourceKey,culture);
    }

    #endregion

    private ResourceManager CreateResourceManager(string classKey,Assembly assembly)
    {
        return new ResourceManager(classKey,assembly);
    }
}

UPD

RESidation for ValidationResources

只需将新资源类添加为ValidationResources并在其中放置提供的XML
