TimeSpanValidator Class

Note: This class is new in the .NET Framework version 2.0.

Provides validation of a TimeSpan.

Namespace: System.Configuration
Assembly: System.Configuration (in system.configuration.dll)

public class TimeSpanValidator : ConfigurationValidatorBase
public class TimeSpanValidator extends ConfigurationValidatorBase
public class TimeSpanValidator extends ConfigurationValidatorBase

The TimeSpanValidator class is used to ensure a TimeSpan meets specific criteria. There are four constructor overloads for the TimeSpanValidator class. The TimeSpanValidator constructor with one parameter verifies a minimum value for a TimeSpan object. The TimeSpanValidator constructor with two parameters ensures that both a minimum and a maximum TimeSpan are adhered to. The TimeSpanValidator constructor with three parameters checks both the minimum and maximum TimeSpan values, as well as whether the validation range is exclusive. The TimeSpanValidator constructor with four parameters checks the previous three parameters and also checks whether the TimeSpan is equal to a specific number of seconds.

The CanValidate method determines whether the object type being validated matches the expected type. The object being validated is passed as a parameter of the Validate method.

The following code example demonstrates how to use the TimeSpanValidator type.

using System;
using System.Configuration;

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

      // 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",

        // Attempt validation.
      catch (ArgumentException e)
        // Validation failed.
        Console.WriteLine("Error: {0", e.Message.ToString());

      // Display and wait
