TimeSpanValidatorAttribute 构造函数

定义

命名空间:

System.Configuration

程序集:

System.Configuration.ConfigurationManager.dll

包:

System.Configuration.ConfigurationManager v8.0.0

Source:

TimeSpanValidatorAttribute.cs

初始化 TimeSpanValidatorAttribute 类的新实例。

public:
 TimeSpanValidatorAttribute();

public TimeSpanValidatorAttribute ();

Public Sub New ()

示例

下面的示例演示如何使用 StringValidatorAttribute 构造函数。

            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 '

注解

在特性化模型中使用此构造函数，以确保分配给相关属性的值的类型是 TimeSpan 对象。
