Item Property

Summary

Gets the AudioInput item with the specified name.

Syntax

C++/CLI

public AudioInput Item( 
   string name 
) { get; }

public: 
property AudioInput^ Item { 
   AudioInput^ get(String^ name); 
}

Parameters

name
The string name of the item to get.

Property Value

The AudioInput item with the specified name.

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.
System.NullReferenceException	The 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. Audio Input names are unique. An application can use this method to find a specific input. An Audio Input name can be retrieved with the AudioInput.Name property. If the method fails, an error is raised. For more information, refer to the Error Codes.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public CaptureCtrlForm _form = new CaptureCtrlForm(); 
 
public void IndexContainsExample() 
{ 
   try 
   { 
      // reference the form capture control 
      CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
      // set an audio device first.  use your audio device's name here 
      if (capturectrl.AudioDevices["USB"] == null) 
         throw new Exception("No USB audio device available"); 
 
      capturectrl.AudioDevices["USB"].Selected = true; 
 
      // reference the form capture control's audio inputs 
      AudioInputs inputs = capturectrl.AudioInputs; 
 
      // check for the master volume input 
      int i = inputs.IndexOf("Master Volume"); 
 
      // access the input via the collection indexer 
      AudioInput ai = inputs[i]; 
 
      // check whether the collection contains this input  
      // (it should we just got it with IndexOf above!) 
      if (inputs.Contains(ai)) 
      { 
         // set the result to what we expect 
         _result = true; 
      } 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
}
