Item(Int32) Property

Example 





The zero-based index of the item to get or set.
Gets or sets the Processor item at the specified index.
Syntax
public Processor Item( 
   int index
) {get; set;}
'Declaration
 
Public Overloads Property Item( _
   ByVal index As Integer _
) As Processor
'Usage
 
Dim instance As Processors
Dim index As Integer
Dim value As Processor
 
instance.Item(index) = value
 
value = instance.Item(index)
public Processor Item( 
   int index
) {get; set;}
 get_Item(Int32)();
set_Item(Int32)(value);
public:
property Processor^ Item {
   Processor^ get(int index);
   void set (int indexProcessor^ value);
}

Parameters

index
The zero-based index of the item to get or set.

Property Value

The Processor item at the specified index.
Exceptions
ExceptionDescription
System.ArgumentOutOfRangeExceptionThe exception that is thrown when the value of an argument is outside the allowable range of values as defined by the invoked method.
Remarks
This property provides the ability to access a specific item in the collection by using the following syntax: myCollection[index] The C# language uses the this keyword to define the indexers instead of implementing the Item property. Visual Basic implements Item as a default property, which provides the same indexing functionality.
