Convert File to byte array Angular 2
提问by C.Daniel
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?
如何使用 Angular2 将输入文件（例如图像）转换为字节数组？也许有人可以说什么更好：将图像转换为字节数组并将其发送到 Web API 或将文件“对象”发送到 API 并在那里进行转换？

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
你不会真正使用 Angular 来解决这个任务。JavaScript 具有处理文件数据的 API，例如 https://developer.mozilla.org/en-US/docs/Web/API/FileReader/readAsArrayBuffer
PS: "Angular 2" is just called "Angular" now, because they're on version 4:
PS：“Angular 2”现在被称为“Angular”，因为它们在版本 4 上：
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.
正如您可能已经猜到的那样，一旦我们到达版本 4、5 等，术语“Angular 2”也被弃用了。也就是说，我们应该开始将它简单地命名为“Angular”，而没有版本后缀。

Unless you mean you are using an older version of Angular (from closer to when "Angular 2" released).
除非您的意思是您使用的是旧版本的 Angular（从更接近于“Angular 2”发布时）。
