Syntax
'Declaration
Protected Sub ValidateProperty ( _
propertyName As String, _
value As Object _
)
'Usage
Dim propertyName As String
Dim value As Object
Me.ValidateProperty(propertyName, _
value)
protected void ValidateProperty(
string propertyName,
Object value
)
protected:
void ValidateProperty(
String^ propertyName,
Object^ value
)
member ValidateProperty :
propertyName:string *
value:Object -> unit
protected function ValidateProperty(
propertyName : String,
value : Object
)
Parameters
- propertyName
Type: System.String
The name of the property to validate.
- value
Type: System.Object
The value to test. It may be nulla null reference (Nothing in Visual Basic) if nulla null reference (Nothing in Visual Basic) is valid for the specified property.
Exceptions
| Exception | Condition |
|---|---|
| ArgumentNullException | propertyName is nulla null reference (Nothing in Visual Basic). |
| InvalidOperationException | The property is marked with EditableAttribute configured to prevent editing. |
Remarks
This method evaluates the ValidationAttribute associated with the specified property, accumulating the validation errors and surfacing them through the ValidationErrors property.
This method also verifies that the property is not read-only.
All validation logic is bypassed if this instance is currently being deserialized.

Return m_address

{
return this.address;
}
