Item Property

Summary
Gets or sets the Processor item at the specified index.
Syntax
C#
C++/CLI
public Processor Item( 
   int index 
) { get; set; } 
public: 
property Processor^ Item { 
   Processor^ get(int index); 
   void set (int index, Processor^ ); 
} 

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. VB implements Item as a default property, which provides the same indexing functionality.

Example
C#
using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public PlayCtrlForm _form = new PlayCtrlForm(); 
 
public void IndexOfExample() 
{ 
   // reference the play control 
   PlayCtrl playctrl = _form.PlayCtrl; 
 
   try 
   { 
      // get the play controls available audio processors 
      AudioProcessors allProcs = playctrl.AudioProcessors; 
 
      // get the play controls selected audio processors 
      AudioProcessors selProcs = playctrl.SelectedAudioProcessors; 
 
      // add a couple processors to the selected audio processors collection 
      selProcs.Add(allProcs.Chorus); 
      selProcs.Add(allProcs.Echo); 
 
      // get the indexes of added audio processors 
      int i = selProcs.IndexOf(allProcs.Chorus); 
      int j = selProcs.IndexOf(allProcs.Echo); 
 
      // set the result to what we expect 
      _result = (selProcs[i] == selProcs.Chorus && selProcs[j] == selProcs.Echo); 
      //_result = (i > -1 && j > -1 && i != j); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
}
