範例

以下程式碼範例示範如何使用該 TimeSpanValidator 型別。

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

備註

這個 TimeSpanValidator 類別用來確保 TimeSpan 物件符合特定條件。 帶有兩個參數的 TimeSpanValidator 建構子確保同時遵守最小值與最大 TimeSpan 值。 擁有三個參數的 TimeSpanValidator 建構子檢查最小值與最大 TimeSpan 值，以及驗證範圍是否為排他性。 擁有四個參數的 TimeSpanValidator 建構子會檢查前三個參數，並檢查該 TimeSpan 值是否等於特定秒數。

該方法判斷 CanValidate 被驗證的物件型別是否符合預期型別。 被驗證的物件會作為方法的 Validate 參數傳遞。
