                        elem.bind("change", function () {
                            $parse(attrs.fileInput).assign(scope, elem[0].files);
                            scope.$apply();
                        });
                    }
                }
            })
.controller("imageUploadPracticeController", function ($scope,$http,$timeout) {

On the client side, you have a load complete handler on your image (I assume that's the image you want in the database):

JavaScript

vm.imageIsLoaded = function (e) {
    $scope.$apply(function () {
        vm.step = e.target.result;
    });
}

You want to send that e.target.result to the server in your service call. Once there you parse off the beginning text that just identifies the media type. Then you have a perfectly good image as a base64 string. You can store it in the database as text, or continue on to convert to an Image and store it that way:

C#

string imageString = ThisValueIsETargetResultFromClient; // e.target.result;
imageString = imageString.Substring(imageString.IndexOf(",") + 1); // remove meta
// Now can save imageString to database as base 64 string, or

using(MemoryStream ms = new MemoryStream(Convert.FromBase64String(imageString)))
{
      System.Drawing.Image image = System.Drawing.Bitmap.FromStream(ms);
      // Now can save image to database as Image file
}
