获取此集合的枚举器。
public:
System::Collections::IEnumerator ^ GetEnumerator();
public:
virtual System::Collections::IEnumerator ^ GetEnumerator();
public System.Collections.IEnumerator GetEnumerator ();
member this.GetEnumerator : unit -> System.Collections.IEnumerator
abstract member GetEnumerator : unit -> System.Collections.IEnumerator
override this.GetEnumerator : unit -> System.Collections.IEnumerator
Public Function GetEnumerator () As IEnumerator
返回
IEnumerator 类型的枚举数。
实现
示例
下面的代码示例获取 上的 button1
属性的枚举器。 它使用 枚举器打印集合中属性的名称。 它假定 button1
已在窗体上创建了 和 textBox1
。
private:
void MyEnumerator()
{
// Creates a new collection and assigns it the attributes for button1.
AttributeCollection^ attributes;
attributes = TypeDescriptor::GetAttributes( button1 );
// Creates an enumerator for the collection.
System::Collections::IEnumerator^ ie = attributes->GetEnumerator();
// Prints the type of each attribute in the collection.
Object^ myAttribute;
System::Text::StringBuilder^ text = gcnew System::Text::StringBuilder;
while ( ie->MoveNext() == true )
{
myAttribute = ie->Current;
text->Append( myAttribute );
text->Append( '\n' );
}
textBox1->Text = text->ToString();
}
private void MyEnumerator() {
// Creates a new collection and assigns it the attributes for button1.
AttributeCollection attributes;
attributes = TypeDescriptor.GetAttributes(button1);
// Creates an enumerator for the collection.
System.Collections.IEnumerator ie = attributes.GetEnumerator();
// Prints the type of each attribute in the collection.
Object myAttribute;
while(ie.MoveNext()==true) {
myAttribute = ie.Current;
textBox1.Text += myAttribute.ToString();
textBox1.Text += '\n';
}
}
Private Sub MyEnumerator
' Creates a new collection and assigns it the attributes for button1.
Dim attributes As AttributeCollection
attributes = TypeDescriptor.GetAttributes(button1)
' Creates an enumerator for the collection.
Dim ie As System.Collections.IEnumerator = attributes.GetEnumerator
' Prints the type of each attribute in the collection.
Dim myAttribute As Object
Do While ie.MoveNext
myAttribute = ie.Current
textBox1.Text = textBox1.Text & myAttribute.toString & ControlChars.crlf
Loop
End Sub
