示例

下面的代码示例演示如何使用 TimeSpanValidator 类型。

using System;
using System.Configuration;

namespace Samples.AspNet
{
  class UsingTimeSpanValidator
  {
    static void Main(string[] args)
    {
      // Display title.
      Console.WriteLine("ASP.NET Validators");
      Console.WriteLine();

      // Create TimeSpan and Validator.
      TimeSpan testTimeSpan = new TimeSpan(0,1,05);
      TimeSpan minTimeSpan = new TimeSpan(0,1,0);
      TimeSpan maxTimeSpan = new TimeSpan(0,1,10);
      TimeSpanValidator myTimeSpanValidator = new TimeSpanValidator(minTimeSpan, maxTimeSpan, false, 65);

      // Determine if the object to validate can be validated.
      Console.WriteLine("CanValidate: {0}",
        myTimeSpanValidator.CanValidate(testTimeSpan.GetType()));

      try
      {
        // Attempt validation.
        myTimeSpanValidator.Validate(testTimeSpan);
        Console.WriteLine("Validated.");
      }
      catch (ArgumentException e)
      {
        // Validation failed.
        Console.WriteLine("Error: {0}", e.Message.ToString());
      }

      // Display and wait
      Console.ReadLine();
    }
  }
}

Imports System.Configuration

Namespace Samples.AspNet
  Class UsingStringValidator
    Public Shared Sub Main()

      ' Display title.
      Console.WriteLine("ASP.NET Validators")
      Console.WriteLine()

      ' Create string and validator.
      Dim testVal As String = "filename"
      Dim myStrValidator As StringValidator = New StringValidator(1, 8, "$%^")

      ' Create TimeSpan and Validator.
      Dim testTimeSpan As TimeSpan = New TimeSpan(0, 1, 5)
      Dim minTimeSpan As TimeSpan = New TimeSpan(0, 1, 0)
      Dim maxTimeSpan As TimeSpan = New TimeSpan(0, 1, 10)
      Dim myTimeSpanValidator As TimeSpanValidator = _
       New TimeSpanValidator(minTimeSpan, maxTimeSpan, False, 65)

      ' Determine if the object to validate can be validated.
      Console.WriteLine("CanValidate: {0}", _
        myTimeSpanValidator.CanValidate(testTimeSpan.GetType()))

      Try
        ' Attempt validation.
        myTimeSpanValidator.Validate(testTimeSpan)
        Console.WriteLine("Validated.")

      Catch e As Exception
        ' Validation failed.
        Console.WriteLine("Error: {0}", e.Message.ToString())
      End Try

      ' Display and wait.
      Console.ReadLine()
    End Sub
  End Class
End Namespace

注解

类 TimeSpanValidator 用于确保 TimeSpan 对象满足特定条件。 具有两个参数的 TimeSpanValidator 构造函数可确保同时遵循最小值和最大值 TimeSpan 。 具有三个参数的 TimeSpanValidator 构造函数会检查最小值和最大值 TimeSpan ，以及验证范围是否独占。 具有四个参数的 TimeSpanValidator 构造函数会检查前三个参数， TimeSpan 并检查该值是否等于特定的秒数。

方法 CanValidate 确定要验证的对象类型是否与预期类型匹配。 正在验证的对象作为 方法的参数 Validate 传递。
