How to build base64 rest web service to upload image file with other information

I want to build a Rest Web Service (in .NET) to upload image file with other information like name, description, time etc.

So I have write this code:

[Route("SaveDocument")]
[HttpPost]
public HttpResponseMessage SaveDocument(Stream fileContents)
{

    byte[] buffer = new byte[10000];
    int bytesRead, totalBytesRead = 0;
    do
    {
    bytesRead = fileContents.Read(buffer, 0, buffer.Length);
    totalBytesRead += bytesRead;
    } while (bytesRead > 0);
    Console.WriteLine("Service: Received file {0} with {1} bytes", fileName, totalBytesRead);

}

I want pass file Base64 and I'm not able to do this.

Can we help me?

You should wrap your base64 data in an JSON object with your additional information and parse it on your REST backend:

{
    "fileName": "example.jpg",
    "content": "base64-content",
    "creationTime": "2015-10-27T00:10:00"
}

Create some models for your file on the server side and parse your response into objects with the following: https://msdn.microsoft.com/en-us/library/hh674188.aspx

You can then save your file to the disk on your backend with the following command:

File.WriteAllBytes(@"c:\yourfile", Convert.FromBase64String(yourBase64String));
