TimeSpanValidator Class
Assembly: System.Configuration (in system.configuration.dll)
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.
Imports System 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
