Summary

Syntax
C#
C++/CLI
public TargetDevice Item( 
   int index 
) { get; } 
public: 
property TargetDevice^ Item { 
   TargetDevice^ get(int index); 
} 

Parameters

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

Property Value

The TargetDevice 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 ConvertCtrlForm _form = new ConvertCtrlForm(); 
 
public void IndexContainsExample() 
{ 
   // reference the capture control 
   ConvertCtrl convertctrl = _form.ConvertCtrl; 
 
   // input file 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_Source.avi"); 
 
   try 
   { 
      // set the input file 
      convertctrl.SourceFile = inFile; 
 
      // reference the video target devices object 
      TargetDevices devices = convertctrl.TargetDevices; 
 
      // check the index of an HD Audio device 
      int i = devices.IndexOf("HD Audio"); 
 
      TargetDevice dev = null; 
      if (i > -1) 
         // access the input via the collection indexer 
         dev = devices[i]; 
 
      // check whether the collection contains this input  
      // (it should we just got it with IndexOf above) 
      if (devices.Contains(dev)) 
      { 
         // set the result to what we expect 
         _result = true; 
      } 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
}
