I would like some help to know how to upload an image using webservice c #, I've tried several forms and several examples but I could not.
I have tried to convert an image to base64 string, I did not succeed. The form for communication between the webservice I used the KSOAP2 library, I also tried JSON, HTTP POST ... Some rotate however do not send photo 640 x 480.
Thank you in advance.
To upload a photo, you can use the WebInvoke annotation, which allows you to create WCF endpoints in REST format. Here's the code snippet to explain:
[WebInvoke(UriTemplate = "UploadPhoto/{fileName}/{description}", Method = "POST")]
public void UploadPhoto(string fileName, string description, Stream fileContents)
{
byte[] buffer = new byte[32768];
MemoryStream ms = new MemoryStream();
int bytesRead, totalBytesRead = 0;
do
{
bytesRead = fileContents.Read(buffer, 0, buffer.Length);
totalBytesRead += bytesRead;
ms.Write(buffer, 0, bytesRead);
} while (bytesRead > 0);
// Save the photo on database.
using (DataAcess data = new DataAcess())
{
var photo = new Photo() { Name = fileName, Description = description, Data = ms.ToArray(), DateTime = DateTime.UtcNow };
data.InsertPhoto(photo);
}
ms.Close();
Console.WriteLine("Uploaded file {0} with {1} bytes", fileName, totalBytesRead);
}
