AngularJS how return a string instead of Json object

Question

I use angularjs to get a string from a web service. This string is actually a base64 pdf file.

public string Get(int id)
{
    var bytes = File.ReadAllBytes(@"C:\test.pdf");
    var content = Convert.ToBase64String(bytes);
    return content;
}

Angularjs return me a array like this one:

{"0":"\"","1":"J","2":"V","3":"B","4":"E" ...}

But I need a complete string like this : "JVBE..."

I try to find a way to get the complete string instead of array format and I don't find anything.

Do you know how handle this?

Thank you!

I don't see any Angular JS code here.. either no Javascript... It looks like you are mixing Java & Javascript. There is no var keyword in Java and so no File.ReadAllBytes() function in Javascript. Your Get function must return an error at execution/compilation.. — Merlin

@Lorenzo, actually it looks like C# code (there is var in C#). But you're right anyway, no JS here at all :) — Michal Leszczyk

It seems that you are returning data from .Net MVC's Web API. You can do

public object Get(int id)
{
    var bytes = File.ReadAllBytes(@"C:\test.pdf");
    var content = Convert.ToBase64String(bytes);
    return new {value = content};
}

Since a string can't be converted to JSON.

That give a anonymous return type... Are you sure this is the good way?

@Karine If that is your C# code of your web API, then the answer is yes.
