Examples
The following code example gets an enumerator for the properties on button1
. It uses the enumerator to print the names of the properties in the collection. It requires that button1
and textBox1
have been instantiated on a form.
private:
void MyEnumerator()
{
// Creates a new collection and assigns it the properties for button1.
PropertyDescriptorCollection^ properties = TypeDescriptor::GetProperties( button1 );
// Creates an enumerator.
IEnumerator^ ie = properties->GetEnumerator();
// Prints the name of each property in the collection.
Object^ myProperty;
while ( ie->MoveNext() == true )
{
myProperty = ie->Current;
textBox1->Text = textBox1->Text + myProperty + "\n";
}
}
private void MyEnumerator() {
// Creates a new collection and assigns it the properties for button1.
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(button1);
// Creates an enumerator.
IEnumerator ie = properties.GetEnumerator();
// Prints the name of each property in the collection.
Object myProperty;
while(ie.MoveNext()==true) {
myProperty = ie.Current;
textBox1.Text += myProperty.ToString() + '\n';
}
}
Private Sub MyEnumerator()
' Creates a new collection and assigns it the properties for button1.
Dim properties As PropertyDescriptorCollection = _
TypeDescriptor.GetProperties(button1)
' Creates an enumerator.
Dim ie As IEnumerator = properties.GetEnumerator()
' Prints the name of each property in the collection.
Dim myProperty As Object
While ie.MoveNext() = True
myProperty = ie.Current
textBox1.Text &= myProperty.ToString() & ControlChars.Cr
End While
End Sub
