TimeSpanValidatorAttribute 建構函式

定義

命名空間:

System.Configuration

組件:

System.Configuration.ConfigurationManager.dll

套件:

System.Configuration.ConfigurationManager v8.0.0

來源:

TimeSpanValidatorAttribute.cs

初始化 TimeSpanValidatorAttribute 類別的新執行個體。

public:
 TimeSpanValidatorAttribute();

public TimeSpanValidatorAttribute ();

Public Sub New ()

範例

下列範例將示範如何使用這個 StringValidatorAttribute 建構函式。

            ConfigurationValidatorBase valBase;
            TimeSpanValidatorAttribute tsValAttr;
            tsValAttr = new TimeSpanValidatorAttribute();

            TimeSpan goodValue = TimeSpan.FromMinutes(10);
            Int16 badValue = 10;

            try
            {
                valBase = tsValAttr.ValidatorInstance;
                valBase.Validate(goodValue);
                // valBase.Validate(badValue);
            }
            catch (ArgumentException e)
            {
                // Display error message.
                string msg = e.ToString();
#if DEBUG
                Console.WriteLine(msg);
#endif
            }

        Dim valBase As ConfigurationValidatorBase
        Dim tsValAttr As TimeSpanValidatorAttribute
        tsValAttr = New TimeSpanValidatorAttribute()

        Dim goodValue As TimeSpan = TimeSpan.FromMinutes(10)
        Dim badValue As Int16 = 10

        Try
            valBase = tsValAttr.ValidatorInstance
            valBase.Validate(goodValue)
            ' valBase.Validate(badValue);
        Catch e As ArgumentException
            ' Display error message.
            Dim msg As String = e.ToString()

#If DEBUG Then
            Console.WriteLine(msg)
#End If
        End Try '

備註

您會在屬性化模型中使用此建構函式，以確保指派給相關屬性的值類型是 TimeSpan 物件。
