ValidateRangeAttribute Class

Defines an attribute that uses minimum and maximum values to validate a cmdlet parameter argument. (This attribute can also be used by Windows PowerShell functions.) This class cannot be inherited.


Namespace: System.Management.Automation
Assembly: System.Management.Automation (in System.Management.Automation.dll)

'Usage
Dim instance As ValidateRangeAttribute

[AttributeUsageAttribute(AttributeTargets.Property|AttributeTargets.Field)] 
public sealed class ValidateRangeAttribute : ValidateEnumeratedArgumentsAttribute
/** @attribute AttributeUsageAttribute(AttributeTargets.Property|AttributeTargets.Field) */ 
public final class ValidateRangeAttribute extends ValidateEnumeratedArgumentsAttribute
AttributeUsageAttribute(AttributeTargets.Property|AttributeTargets.Field) 
public final class ValidateRangeAttribute extends ValidateEnumeratedArgumentsAttribute

This example specifies a range of 0 to 5 for the InputData parameter.

[ValidateRange(0, 5)]
[Parameter(Position = 0, Mandatory = true)]
public int InputData
{
  get { return inputData; }
  set { inputData = value; }
}

private int inputData;

There are no established scenarios for explicitly creating a ValidateRangeAttribute object from within a cmdlet. The ValidateRangeAttribute object is created and used indirectly when the attribute is declared.

The cmdlet declares this attribute when implementing a cmdlet parameter. For more information about the syntax and parameters used to declare this attribute within a cmdlet, see ValidateRange Attribute Declaration.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
