C++/CLI
public Processor Item( 
   string name 
) { get; set; } 
public: 
property Processor^ Item { 
   Processor^ get(String^ name); 
   void set (String^ name, Processor^ ); 
} 

Parameters

name
The string name of the item to get or set.

Property Value

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.
System.NullReferenceExceptionThe exception that is thrown when there is an attempt to dereference a null object reference.
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.MediaFoundation; 
using LeadtoolsMediaFoundationExamples.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; 
 
      // get index of LEAD MF Volume Transform 
      int nIndex = allProcs.IndexOf("{E2B7DC41-38C5-11D5-91F6-00104BDB8FF9}"); 
 
      // get LEAD MF Volume Transform 
      Processor AudProc = allProcs[nIndex]; 
 
      // add the LEAD MF Volume Transform to the selected audio processors 
      selProcs.Add(AudProc); 
 
      // get the index of added audio processor 
      int i = selProcs.IndexOf(AudProc); 
 
      // set the result to what we expect 
      _result = (selProcs[i] == AudProc); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
}
