So far I found something related to what I am looking for, but I'm not sure if this is what I need: link
How do I convert the file to byte in js and send it to webservices to upload to server.
Example:
JS:
<script>
webService.UploadFile(Myfilebytes,suc,fail);
</script>
C#:
[Web Method]
public string UploadFile(byte[] Myfilebytes)
{
//UPloading script
return "OK";
}
You don't convert the file to a byte array; it already is one. Your browser manages the responsibility of formatting the data to send to a web service. Typically this is achieved through a POST on a form with an input of type file:
<form enctype="multipart/form-data" action="UploadFile" method="post">
<input id="image" type="file" />
</form>
Using a WebMethod on the C# side is not possible, however, as POST variables are received through the request information, of which a WebMethod does not provide. You can create a web handler and use the ProcessRequest method to receive this info, but this is not the only way.
