NameDescription
System_CAPS_pubmethodStringValidatorAttribute()

Initializes a new instance of the StringValidatorAttribute class.

NameDescription
System_CAPS_pubpropertyInvalidCharacters

Gets or sets the invalid characters for the property.

System_CAPS_pubpropertyMaxLength

Gets or sets the maximum length allowed for the string to assign to the property.

System_CAPS_pubpropertyMinLength

Gets or sets the minimum allowed value for the string to assign to the property.

System_CAPS_pubpropertyTypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

System_CAPS_pubpropertyValidatorInstance

Gets an instance of the StringValidator class.(Overrides ConfigurationValidatorAttribute.ValidatorInstance.)

System_CAPS_pubpropertyValidatorType

Gets the type of the validator attribute.(Inherited from ConfigurationValidatorAttribute.)

NameDescription
System_CAPS_pubmethodEquals(Object)

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodGetHashCode()

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethodMatch(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfoCount(UInt32)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

You use the StringValidatorAttribute to decorate a configuration property. This is to instruct the .NET Framework to validate the property using the StringValidator and pass to it the value of the decorating parameters.

You can apply StringValidatorAttribute objects to property types only.

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

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