Extract text from PPT using Aspose.Slides for .NET

I am modifying an existing method that was extracting text using old Aspose.slide interface. But I can’t find any getPlaceholders() method for Islide and TextHolder is also unknown. Here is my code:

ISlide islide = srcPres.getSlides().get_Item(i);
// By shapes

// By plaseholder
for (int j = 0; j < islide.getPlaceholders().getCount(); j++) {
Placeholder holder = islide.getPlaceholders().get_Item(j);
if (holder instanceof TextHolder)
mpTHA.handleText(TS_PLACEHOLDER, ((TextHolder) holder).getText(), holder);

As mentioned above I can’t find any method getPlaceholders() for iSlide and TextHolder is also unknown. I am using aspose.slides API 18.5
