IntegerValidator Class

Provides validation of an Int32 value.

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

public class IntegerValidator : ConfigurationValidatorBase
public class IntegerValidator extends ConfigurationValidatorBase
public class IntegerValidator extends ConfigurationValidatorBase
Not applicable.

The IntegerValidator class is used to ensure that an integer meets specific criteria. The criteria for validation is established when an instance of the IntegerValidator class is created. The IntegerValidator constructor with two parameters ensures that the integer being verified adheres to both a minimum and a maximum length. The IntegerValidator constructor with three parameters checks both the minimum and maximum Int32 values, as well as whether the validation range is exclusive. The IntegerValidator constructor with four parameters checks the previous three parameters and also checks whether the Int32 value is equal to a specific resolution.

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 IntegerValidator type.

using System;
using System.Configuration;

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

      // Create Integer and Validator.
      int testInt = 5;
      int minIntVal = 1;
      int maxIntVal = 10;
      IntegerValidator myIntegerValidator = 
	new IntegerValidator(minIntVal, maxIntVal, false);

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

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

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

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
