      TargetFormats formats = capturectrl.TargetFormats; 
 
      // check the index using a name string 
      int i = formats.IndexOf("WAVE"); 
 
      // or get a target format directly, using a TargetFormatType enum 
      TargetFormat mpeg1 = formats[TargetFormatType.MPEG1Audio];

      TargetFormat af = formats[i]; 
 
      // check whether the collection contains this format  
      // (it should we just got it with IndexOf above) 
      if (formats.Contains(af) && formats.Contains(mpeg1)) 
      {
