In Umbraco 7, I'm using the following method and its working fine

   private void SaveMediaUsingMediaService(string sourceImageName, out IMedia newMedia, int parentFolderId, byte[] mediaBuffer, string mediaType, out string tempurl, string fileName)
        {
            newMedia = _mediaService.CreateMedia(sourceImageName, parentFolderId, mediaType);
            tempurl = "";
            newMedia.SetValue("umbracoFile", sourceImageName, new MemoryStream(mediaBuffer));
            _mediaService.Save(newMedia);
            if (mediaType == "File")
            {
                tempurl = newMedia.GetValue("umbracoFile").ToString();
            }
            else
            {
                dynamic mediaInfo = JsonConvert.DeserializeObject(newMedia.GetValue("umbracoFile").ToString());
                tempurl = mediaInfo.src;
            }
            if (System.IO.File.Exists(fileName))
            {
                System.IO.File.Delete(fileName);
            }
        }

This is the one I'm trying to use on Umbraco version 11

This just create dummy file on media section but content empty as below image

  private void SaveMediaUsingMediaService(string sourceImageName, out IMedia newMedia, int parentFolderId, byte[] mediaBuffer, string mediaType, out string tempurl, string fileName)
        {
            newMedia = _mediaService.CreateMedia(sourceImageName, parentFolderId, mediaType);
            tempurl = "";
            newMedia.SetValue("umbracoFile", fileName);
            _mediaService.Save(newMedia);
            if (mediaType == "File")
            {
                tempurl = newMedia.GetValue("umbracoFile").ToString();
            }
            else
            {
                dynamic mediaInfo = JsonConvert.DeserializeObject(newMedia.GetValue("umbracoFile").ToString());
                tempurl = mediaInfo.src;
            }
            if (System.IO.File.Exists(fileName))
            {
                System.IO.File.Delete(fileName);
            }
        }

Did you try the code example in the link I posted? (it does not appear to be the same code as you are currently trying)

Hi Huw, Yes I tried But SetValue Method signature bit different in Umbraco 11 than mentioned in the documentation it accepts only these parameters.

SetValue(string propertyTypeAlias, object? value, string? culture = null, string? segment = null);

But I need to set the value for the media URL. If I parse only the first two parameters it only creates a dummy file in Umbraco media, not the actual image I added.

you don't appear to be passing the stream in the setvalue call (last value passed in the method, after filename.

    media.SetValue(_mediaFileManager, _mediaUrlGeneratorCollection, _shortStringHelper, _contentTypeBaseServiceProvider, Constants.Conventions.Media.File, "unicorn.jpg", stream);

Yes, but about method signature is different. It doesn't accept stream

Not sure what you are doing then, as the SetValue method does accept a stream in Umbraco 11, exactly as shown in the example from the documentation.

There are 2 overloads for that method

Thanks, but I can't see two overloads in IContentBase Interface. That is the issue

Please correct me if you see I missed anything. Also if you need I can show you my full method

Full method would help since you should have an Imedia object not Icontentbase

Hi Huw, I'm creating IMedia object. Please check my method

private void SaveMediaUsingMediaService(string sourceImageName, out IMedia newMedia, int parentFolderId, byte[] mediaBuffer, string mediaType, out string tempurl, string fileName)
{

    try
    {
        newMedia = _mediaService.CreateMedia(sourceImageName, parentFolderId, mediaType);
        tempurl = "";
        newMedia.SetValue("umbracoFile", new MemoryStream(mediaBuffer));
        _mediaService.Save(newMedia);
        if (mediaType == "File")
        {
            tempurl = newMedia.GetValue("umbracoFile").ToString();
        }
        else
        {
            dynamic mediaInfo = JsonConvert.DeserializeObject(newMedia.GetValue("umbracoFile").ToString());
            tempurl = mediaInfo.src;
        }
        if (System.IO.File.Exists(fileName))
        {
            System.IO.File.Delete(fileName);
        }
    }
    catch (Exception ex)
    {
        tempurl = "";
        newMedia=null;
    }
}

you are not passing in the correct values which is why it is defaulting to the wrong overload, you need to pass ALL the correct values as shown in the example and in my post above, one of those is the stream, you can't just pass in 2 values like you are attempting.

Method signature for SetValue

   public static void SetValue(this Umbraco.Cms.Core.Models.IContentBase content, 
    Umbraco.Cms.Core.IO.MediaFileManager mediaFileManager,
    Umbraco.Cms.Core.PropertyEditors.MediaUrlGeneratorCollection mediaUrlGenerators, 
    Umbraco.Cms.Core.Strings.IShortStringHelper shortStringHelper, 
    Umbraco.Cms.Core.Services.IContentTypeBaseServiceProvider contentTypeBaseServiceProvider, 
    string propertyTypeAlias, 
    string filename, 
    System.IO.Stream filestream, 
    [string culture = null], 
    [string segment = null])

                Member of Umbraco.Extensions.ContentExtensions

            Summary:
            Sets the posted file value of a property.

Parsed parameters the way you mentioned in the previous reply(Please see attached image) but now it's giving an error saying

error CS1501: No overload for method 'SetValue' takes 10 arguments

remove _contentBase from you method call, it is passed explicitly because it is an extension method, hence the this in the signature definition.

so call it as below.

media.SetValue(_mediaFileManager, _mediaUrlGeneratorCollection, _shortStringHelper, _contentTypeBaseServiceProvider, Constants.Conventions.Media.File, "unicorn.jpg", stream);

Thanks Huw , I had tried this but it still says

No overload for method 'SetValue' takes 7 arguments

 newMedia.SetValue(_mediaFileManager, 
                        _mediaUrlGeneratorCollection, 
                        _shortStringHelper,
                        _contentTypeBaseService, 
                        Constants.Conventions.Media.File, 
                        "unicorn.jpg", 
                        stream);

Did you try this previously Umbraco version 11?

Thanks. Let me try this on a sample project and let you know the results

Hi Huw, I was trying to implement this function in the separate class library and it has some other functions as well. After moving the saving function to a separate class this is working fine.

Thanks a lot for your support, Now I'm trying to identify what is the actual reason for not working with the same class previously added. I will update the thread after I found the reason. Thanks again.

Glad you got it working.
