TimeSpanValidator Class


The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Provides validation of a TimeSpan object.

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


public class TimeSpanValidator : ConfigurationValidatorBase

System_CAPS_pubmethodTimeSpanValidator(TimeSpan, TimeSpan)

Initializes a new instance of the TimeSpanValidator class, based on supplied parameters.

System_CAPS_pubmethodTimeSpanValidator(TimeSpan, TimeSpan, Boolean)

Initializes a new instance of the TimeSpanValidator class, based on supplied parameters.

System_CAPS_pubmethodTimeSpanValidator(TimeSpan, TimeSpan, Boolean, Int64)

Initializes a new instance of the TimeSpanValidator class, based on supplied parameters.


Determines whether the type of the object can be validated.(Overrides ConfigurationValidatorBase.CanValidate(Type).)


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)


Determines whether the value of an object is valid.(Overrides ConfigurationValidatorBase.Validate(Object).)

The TimeSpanValidator class is used to ensure that a TimeSpan object meets specific criteria. The TimeSpanValidator constructor with two parameters ensures that both a minimum and a maximum TimeSpan value 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 value 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
