AttributeCollection.GetEnumerator 方法
定义
获取此集合的枚举器。Gets an enumerator for this collection.
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。An enumerator of type IEnumerator.
实现
示例
下面的代码示例获取中特性的枚举器 button1 。The following code example gets an enumerator for the attributes on button1. 它使用枚举器输出集合中属性的名称。It uses the enumerator to print the names of the attributes in the collection. 它假定 button1 textBox1 已在窗体上创建和。It assumes that button1 and textBox1 have been created on a form.
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
