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

You can apply the LongValidatorAttribute attribute to property types only.

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

No code example is currently available or this language may not be supported.
