IntegerValidatorAttribute Class

Definition

Namespace:

System.Configuration

Assembly:

System.Configuration.ConfigurationManager.dll

Source:

IntegerValidatorAttribute.cs

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

public ref class IntegerValidatorAttribute sealed : System::Configuration::ConfigurationValidatorAttribute

[System.AttributeUsage(System.AttributeTargets.Property)]
public sealed class IntegerValidatorAttribute : System.Configuration.ConfigurationValidatorAttribute

[<System.AttributeUsage(System.AttributeTargets.Property)>]
type IntegerValidatorAttribute = class
    inherit ConfigurationValidatorAttribute

Examples

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

[ConfigurationProperty("maxAttempts", DefaultValue = 101,
    IsRequired = true)]
[IntegerValidator(MinValue = 1, MaxValue = 100,
    ExcludeRange = true)]
public int MaxAttempts
{
    get
    {
        return (int)this["maxAttempts"];
    }
    set
    {
        this["maxAttempts"] = value;
    }
}

<ConfigurationProperty("maxAttempts", _
DefaultValue:=101, _
IsRequired:=True), _
IntegerValidator(MinValue:=1, _
MaxValue:=100, _
ExcludeRange:=True)> _
Public Property MaxAttempts() As Integer
    Get
        Return Fix(Me("maxAttempts"))
    End Get
    Set(ByVal value As Integer)
        Me("maxAttempts") = value
    End Set
End Property

Remarks

You use the IntegerValidatorAttribute attribute to decorate a configuration property, which will instruct .NET to validate the property using the IntegerValidator object and pass to it the value of the decorating parameters.

You can apply IntegerValidatorAttribute attributes to property types only.

Constructors

IntegerValidatorAttribute()

Creates a new instance of the IntegerValidatorAttribute class.

Properties

ExcludeRange	Gets or sets a value that indicates whether to include or exclude the integers in the range defined by the MinValue and MaxValue property values.
MaxValue	Gets or sets the maximum value allowed for the property.
MinValue	Gets or sets the minimum value allowed for the property.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)
ValidatorInstance	Gets an instance of the IntegerValidator class.
ValidatorType	Gets the type of the validator attribute. (Inherited from ConfigurationValidatorAttribute)

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
