AttributeCollection.Item Property (Int32)

Gets the attribute with the specified index number.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

public virtual Attribute this[
	int index
] { get; }

Parameters

index
Type: System.Int32

The zero-based index of AttributeCollection.

Property Value

Type: System.Attribute
The Attribute with the specified index number.

The index number is zero-based. Therefore, you must subtract 1 from the numerical position of a particular Attribute to access that Attribute. For example, to get the third Attribute, you need to specify myColl[2].

The following code example uses the Item property to print the name of the Attribute specified by the index number in a text box. Because the index number is zero-based, this code example prints the name of the second Attribute in a text box. It assumes button1 and textBox1 have been created on a form.

private void PrintIndexItem() {
    // Creates a new collection and assigns it the attributes for button1.
    AttributeCollection attributes;
    attributes = TypeDescriptor.GetAttributes(button1);

    // Prints the second attribute's name.
    textBox1.Text = attributes[1].ToString();
 }
