问题:

How can I convert input file(image,for example) to byte array by using Angular2 ? Maybe someone can say what is better: convert image to byte array and send it to Web API or send the File "object" to API and there convert it?

You wouldn't really use Angular for solving this task. JavaScript has APIs for handling File data, e.g. https://developer.mozilla.org/en-US/docs/Web/API/FileReader/readAsArrayBuffer

See this question

PS: "Angular 2" is just called "Angular" now, because they're on version 4:

As you might have already guessed, the term “Angular 2” is also kind of deprecated once we get to version 4, 5 etc. That said, we should start naming it simply “Angular” without the version suffix.

Unless you mean you are using an older version of Angular (from closer to when "Angular 2" released).
