private file:File;
this.file = "../assets/image/image.jpg"
I'm pretty sure the typescript compiler is telling you that you can't assign a String to a File type. That is why it's not working. In other words when you say that file is of type File then the typescript compiler is expecting a special kind of object, a File object. If you assign a string to it it will tell you it's wrong. When you write :File it isn't just a decoration, it tells typescript, hey I intend this to be a File, so if I assign anything else, make sure to scream at me.
So you could just do this, if you want a string:
private file:string;
this.file = "../assets/image/image.jpg"
Or if you want a legal File object the doc on File here https://developer.mozilla.org/en/docs/Web/API/File
says this:
new File(
Array parts,
String filename,
BlobPropertyBag properties
);
So :
file:File = new File(this.data , "filename");
Or if you want to be free of charges:
file:any;
On a side note, you should read the doc or the quickstart because if you don't understand typing, then there is no point in using typescript notations in the first place.
