ValidationException 類別

定義

表示使用 ValidationAttribute 類別驗證資料欄位時發生的例外狀況 (Exception)。Represents the exception that occurs during validation of a data field when the ValidationAttribute class is used.

public ref class ValidationException : Exception
public class ValidationException : Exception
[System.Serializable]
public class ValidationException : Exception
type ValidationException = class
    inherit Exception
[<System.Serializable>]
type ValidationException = class
    inherit Exception

備註

如果輸入值與資料欄位的預期資料類型、範圍或模式不符,就會發生驗證例外狀況。A validation exception occurs if an input value does not match the expected data type, range or pattern of the data field. 例如,如果使用者在預期值的資料欄位中輸入整數值 DateTime ,就會發生驗證例外狀況。For example, if a user enters an integer value in a data field that expects a DateTime value, a validation exception occurs.

此類別會使用 ValidationAttribute 類別來自訂驗證。This class uses the ValidationAttribute class to customize validations. ValidationException如果發生驗證錯誤,就會擲回。A ValidationException is thrown if a validation error occurs. 呼叫方法時,會擲 Validate 回例外狀況。The exception is thrown when the Validate method is called. 在驗證期間擲回的所有例外狀況都會包含在 InnerExceptions 集合中。All the exceptions that are thrown during validation are contained in the InnerExceptions collection. 您可以逐一查看集合,以取得每個驗證例外狀況 InnerExceptionsYou can retrieve each validation exception by iterating through the InnerExceptions collection.
