LongValidatorAttribute Class

.NET Framework 2.0

Note: This class is new in the .NET Framework version 2.0.

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

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

Syntax

C++

[AttributeUsageAttribute(AttributeTargets.Property)] 
public sealed class LongValidatorAttribute : ConfigurationValidatorAttribute

/** @attribute AttributeUsageAttribute(AttributeTargets.Property) */ 
public final class LongValidatorAttribute extends ConfigurationValidatorAttribute

JScript

AttributeUsageAttribute(AttributeTargets.Property) 
public final class LongValidatorAttribute extends ConfigurationValidatorAttribute

Remarks

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

You may apply the LongValidatorAttribute to property types only.

Example

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

[ConfigurationProperty("maxUsers", DefaultValue = (long)10000,
    IsRequired = false)]
[LongValidator(MinValue = 1, MaxValue = 10000000,
    ExcludeRange = false)]
public long MaxUsers
{
    get
    {
        return (long)this["maxUsers"];
    
    set
    {
        this["maxUsers"] = value;
