建構函式
| CompareAttribute(String) |
初始化 CompareAttribute 類別的新執行個體。Initializes a new instance of the CompareAttribute class. |
屬性
| ErrorMessage |
取得或設定錯誤訊息，此錯誤訊息會在驗證失敗時與驗證控制項產生關聯。Gets or sets an error message to associate with a validation control if validation fails. (繼承來源 ValidationAttribute) |
| ErrorMessageResourceName |
取得或設定要在驗證失敗時用來查閱 ErrorMessageResourceType 屬性值的錯誤訊息資源名稱。Gets or sets the error message resource name to use in order to look up the ErrorMessageResourceType property value if validation fails. (繼承來源 ValidationAttribute) |
| ErrorMessageResourceType |
取得或設定資源類型，此類型可在驗證失敗時用於查閱錯誤訊息。Gets or sets the resource type to use for error-message lookup if validation fails. (繼承來源 ValidationAttribute) |
| ErrorMessageString |
取得當地語系化的驗證錯誤訊息。Gets the localized validation error message. (繼承來源 ValidationAttribute) |
| OtherProperty |
取得要與目前屬性比較的屬性。Gets the property to compare with the current property. |
| OtherPropertyDisplayName |
取得其他屬性的顯示名稱。Gets the display name of the other property. |
| RequiresValidationContext |
取得值，這個值表示屬性是否需要驗證內容。Gets a value that indicates whether the attribute requires validation context. |
| TypeId |
在衍生類別中實作時，取得這個 Attribute 的唯一識別碼。When implemented in a derived class, gets a unique identifier for this Attribute. (繼承來源 Attribute) |
方法
| Equals(Object) |
傳回值，這個值指出此執行個體是否與指定的物件相等。Returns a value that indicates whether this instance is equal to a specified object. (繼承來源 Attribute) |
| FormatErrorMessage(String) |
根據發生錯誤所在的資料欄位，將格式套用至錯誤訊息。Applies formatting to an error message, based on the data field where the error occurred. |
| GetHashCode() |
傳回這個執行個體的雜湊碼。Returns the hash code for this instance. (繼承來源 Attribute) |
| GetType() |
取得目前執行個體的 Type。Gets the Type of the current instance. (繼承來源 Object) |
| GetValidationResult(Object, ValidationContext) |
檢查指定的值在目前的驗證屬性方面是否有效。Checks whether the specified value is valid with respect to the current validation attribute. (繼承來源 ValidationAttribute) |
| IsDefaultAttribute() |
在衍生類別中覆寫時，表示這個執行個體的值是衍生類別的預設值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (繼承來源 Attribute) |
| IsValid(Object) |
判斷指定的物件值是否有效。Determines whether the specified value of the object is valid. (繼承來源 ValidationAttribute) |
| IsValid(Object, ValidationContext) |
判斷指定的物件是否有效 Determines whether a specified object is valid. |
| Match(Object) |
在衍生類別中覆寫時，會傳回值，表示這個執行個體是否等於指定物件。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (繼承來源 Attribute) |
| MemberwiseClone() |
建立目前 Object 的淺層複製。Creates a shallow copy of the current Object. (繼承來源 Object) |
| ToString() |
傳回代表目前物件的字串。Returns a string that represents the current object. (繼承來源 Object) |
| Validate(Object, String) |
驗證指定的物件。Validates the specified object. (繼承來源 ValidationAttribute) |
| Validate(Object, ValidationContext) |
驗證指定的物件。Validates the specified object. (繼承來源 ValidationAttribute) |
明確介面實作
| _Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) |
將一組名稱對應至一組對應的分派識別項 (Dispatch Identifier)。Maps a set of names to a corresponding set of dispatch identifiers. (繼承來源 Attribute) |
| _Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) |
擷取物件的類型資訊，可以用來取得介面的類型資訊。Retrieves the type information for an object, which can be used to get the type information for an interface. (繼承來源 Attribute) |
| _Attribute.GetTypeInfoCount(UInt32) |
擷取物件提供的類型資訊介面數目 (0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1). (繼承來源 Attribute) |
| _Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) |
提供物件所公開的屬性和方法的存取權。Provides access to properties and methods exposed by an object. (繼承來源 Attribute) |
