    Required properties for creating an image with the Media service

    Hi all,

    I posted an original question here:

    http://our.umbraco.org/forum/umbraco-7/using-umbraco-7/52982-Using-the-Umbraco-media-services-to-create-a-media-item-from-an-image-uploaded-to-a-specified-directory

    Since then, I have made some ground on retrieving the image from a folder based upon the supplied path and creating a new image using System.Drawing.Image however I'm now stuck as to which property of the media object I pass this into.

    My code can be found below:

    public partial class MediaServiceTest : System.Web.UI.Page
{
  protected void Page_Load(object sender, EventArgs e)
  {
    try
    {
      string originalPath = "uploadedImages/test.png";
      IMediaService mediaService = ApplicationContext.Current.Services.MediaService;
      var newImage = mediaService.CreateMedia("myNewImage", -1, "Image");
      System.Drawing.Image image = System.Drawing.Image.FromFile(System.IO.Path.GetFullPath(HttpContext.Current.Server.MapPath(originalPath)));
      newImage.SetValue("umbracoFile", image);
      mediaService.Save(newImage);
    }
    catch (Exception ex)
    {
      var message = ex;
    }

  }
}

    As you can see I have tried to pass the image into umbracoFile but this doesn't seem to have worked and returns the following error:

    "The best overloaded method match for 'Umbraco.Core.Models.ContentBase.SetPropertyValue(string, string)' has some invalid arguments"

    Any help would be greatly appreciated.

    Regards,

    Jason

    Hi,

    I think you can set newImage.Path = "path to your file". And then saving should do the trick.

    Hi Dawoe,

    Unfortunately, it's not as simple as that and that code doesn't actually do anything. Eventually I managed to crack it using this code:

        string originalPath = "uploadedImages\\test.png";
    IMediaService mediaService = ApplicationContext.Current.Services.MediaService;
    var newImage = mediaService.CreateMedia("myTestImage", -1, "Image");
    byte[] buffer = System.IO.File.ReadAllBytes(System.IO.Path.GetFullPath(HttpContext.Current.Server.MapPath(originalPath)));
    System.IO.MemoryStream strm = new MemoryStream(buffer);
    newImage.SetValue("umbracoFile", "myNewImage.png", strm);
    mediaService.Save(newImage);
    if (System.IO.File.Exists(HttpContext.Current.Server.MapPath(originalPath)))
    {
      System.IO.File.Delete(HttpContext.Current.Server.MapPath(originalPath));
    }

    Thank you Jason, I'm trying to do something similar and your example is very helpful.  But I'm running into a glitch - I cannot find a method to check if a media item with the same name exists before I call mediaService.CreateMedia - the only media services methods I've found are GetById and GetMediaByPath, and all I have is the name (like "myTestImage") and the ancestor folder id.

    And, if one traverses from an ancestor folder, what property does one check for a name match?

    I'm doing this in a .cs file, making me wish I could use uQuery...but, no.

    Hi Helen,

    If I understand your question correctly, you are looking to check that a media item with a given name does not exist before creating a new media item in Umbraco. To do this, you can traverse from an ancestor folder and use a bit of Linq to solve your problem.

    int ancestorFolderId = 2039;
IEnumerable<Imedia> images = ms.GetChildren(ancestorFolderId).Where(x => x.Name == "TheImageName");
// Or use .GetDescendants

    This essentially asks Umbraco to give you all of the children of your ancestor folder that have the name "TheImageName". Typically you will only have one image named this so the IEnumerable

    if(images.Count() > 0){
    // Image already exists
    // Access the image and its properties by using images.First()
}else{
    //Image does not exist. Create a new one.
}

    Always ensure that you check you IEnumerable has content before trying to use it though as it will error if you don't.

    Thanks for sharing, Jason, this is excellent.

    My question is how do you use this if you have created your own Media Type, with Image as a component.

    [EDIT]

    I found it - I must use CreateMedia but specify my own Media Type instead of "Image"

    e.g.

    var newImage = mediaService.CreateMedia("myTestImage", -1, "myImageType");
