TimeSpanValidatorAttribute TimeSpanValidatorAttribute TimeSpanValidatorAttribute TimeSpanValidatorAttribute Class


Declaratively instructs the .NET Framework to perform time validation on a configuration property. This class cannot be inherited.

public ref class TimeSpanValidatorAttribute sealed : System::Configuration::ConfigurationValidatorAttribute
public sealed class TimeSpanValidatorAttribute : System.Configuration.ConfigurationValidatorAttribute
type TimeSpanValidatorAttribute = class
    inherit ConfigurationValidatorAttribute
Public NotInheritable Class TimeSpanValidatorAttribute
Inherits ConfigurationValidatorAttribute


The following example shows how to decorate the properties of a custom ConfigurationSection object using the TimeSpanValidatorAttribute attribute.

    DefaultValue = "0:10:0",
    IsRequired = false)]
[TimeSpanValidator(MinValueString = "0:0:30",
    MaxValueString = "5:00:0",
    ExcludeRange = false)]
public TimeSpan MaxIdleTime
        return (TimeSpan)this["maxIdleTime"];
        this["maxIdleTime"] = value;
<ConfigurationProperty("maxIdleTime", _
DefaultValue:="0:10:0", _
IsRequired:=False), _
TimeSpanValidator(MinValueString:="0:0:30", _
MaxValueString:="5:00:0", _
ExcludeRange:=False)> _
Public Property MaxIdleTime() As TimeSpan
        Return CType(Me("maxIdleTime"), TimeSpan)
    End Get
    Set(ByVal value As TimeSpan)
        Me("maxIdleTime") = value
    End Set
End Property

The following example is an excerpt of the configuration file that contains the custom section used by the previous sample.

<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">  
    <section name="custom" type="Microsoft.Samples.AspNet.Configuration.SampleSection, ConfigurationValidatorAttribute" />  
  <custom fileName="NewFile.txt" maxSize="1000" maxAttempts="101" maxUsers="2500" maxIdleTime="00:15:00" />  


You use the TimeSpanValidatorAttribute attribute to decorate a configuration property. This is to instruct the .NET Framework to validate the property using the TimeSpanValidator class and pass to it the value of the decorating parameters.

You can apply TimeSpanValidatorAttribute objects to property types only.
