自定義驗證消息，具體

Question

語言，我有一個模型，它看起來是這樣的：

[LocalizedRegularExpression(@"^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$", "RedesignEmailValidationError")] 
public string EmailAddress { get; set; } 

[Compare("EmailAddress", ErrorMessage = "Emails mismatch!")] 
public string EmailConfirm { get; set; } 

的問題是，該錯誤消息未本地化。處理這個問題的最佳方法是什麼？ PS：我收到需要在模型中的此表單上的語言特定文本;理想情況下，我想使用那裏提供的文字。

Answer 1

此外，如果你不依賴於默認的資源提供者，你必須自己實現它。

像：

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method | AttributeTargets.Property | AttributeTargets.Event)] 
public sealed class LocalizedDisplayNameAttribute : DisplayNameAttribute { 
    public LocalizedDisplayNameAttribute() { 
    } 

    public LocalizedDisplayNameAttribute(object context) { 
    Context = context; 
    } 

    public object Context { get; set; } 

    public override string DisplayName { 
    get { 
     // TODO: override based on CultureInfo.CurrentCulture and Context here 
     return "LocalizedAttributeName"; 
    } 
    } 
} 

[AttributeUsage(AttributeTargets.Property)] 
public class LocalizedCompareAttribute : CompareAttribute { 

    public object Context { get; set; } 

    public LocalizedCompareAttribute(string otherProperty) 
    : base(otherProperty) { 
    } 

    public override string FormatErrorMessage(string name) { 
    // TODO: override based on CultureInfo.CurrentCulture and Context here 
    string format = "Field '{0}' should have the same value as '{1}'."; 
    return string.Format(CultureInfo.CurrentCulture, format, name, OtherPropertyDisplayName);  
    } 
} 

等

用法：

[LocalizedCompare("EmailAddress", Context = "ResourceKey_EmailMismatch")] 
[LocalizedDisplayName("ResourceKey_Email")] 
public string EmailConfirm { get; set; } 

Answer 2

您需要使用ErrorMessageResourceName和ErrorMessageResourceType

應該是這樣的：

[Compare("EmailAddress", ErrorMessageResourceName = "ConfirmEmailErrorMessage", ErrorMessageResourceType=typeof(your_resource_type)] 
public string EmailConfirm { get; set; }
