Item Property

Summary

Gets the Compressor item at the specified index.

Syntax

C++/CLI

public Compressor Item( 
   int index 
) { get; }

public: 
property Compressor^ Item { 
   Compressor^ get(int index); 
}

Parameters

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

Property Value

The Compressor item at the specified index.

Exceptions

Exception	Description
System.ArgumentOutOfRangeException	The 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

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public CaptureCtrlForm _form = new CaptureCtrlForm(); 
 
public void IndexContainsExample() 
{ 
   // reference the capture control 
   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   try 
   { 
      // select a video device, use your device name here instead of Analog 
      if (capturectrl.VideoDevices["Analog"] == null) 
         throw new Exception("No Analog video tuner device available"); 
 
      capturectrl.VideoDevices["Analog"].Selected = true; 
 
      // reference the video compressors object 
      Compressors compressors = capturectrl.VideoCompressors; 
 
      // check the index of a video compressor 
      int i = compressors.IndexOf(capturectrl.VideoCompressors.Mpeg2); 
 
      Compressor cmp = null; 
      if (i > -1) 
         // access the compressor via the collection indexer 
         cmp = compressors[i]; 
 
      // check whether the collection contains this input  
      // (it should we just got it with IndexOf above) 
      if (compressors.Contains(cmp)) 
      { 
         // set the result to what we expect 
         _result = true; 
      } 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
}
