How to get the image URL from Structure Group Metadata using C# TBB

Question

I have created a Structure group Metadata having image field. when I try to read the image url, I am getting the TCM ID.

ItemFields metadataFields = new ItemFields(objSG.Metadata, objSG.MetadataSchema);
foreach (ItemField metadataField in metadataFields)
{
   if (metadataField.Name == SchemaConstant.StructureGroupMetadataSchema.Image)
   {    
     elmSG.SetAttribute(Image, metadataField.ToString());
   }
}

Result: I am getting the value:

• image="Component tcm:720-107060"

Images do not have a URL until they are published, as mentioned by @Nuno.

In your code you'll need to publish the binaries to get a URL you can use either the AddBinary or the PublishBinary method to publish binaries. I'd recommend AddBinary, as shown below:

ItemFields metadataFields = new ItemFields(objSG.Metadata, objSG.MetadataSchema);
foreach (ItemField metadataField in metadataFields)
{
   if (metadataField.Name == SchemaConstant.StructureGroupMetadataSchema.Image)
   {    
     //Add Image to package to be published
     var publishedImage = engine.AddBinary(metadataField.value);
     elmSG.SetAttribute(Image, publishedImage.Url);
   }
}

Additional options and parameters for the AddBinary function can be found in the documentation here: https://sdl.dist.sdlmedia.com/Distributions/?o=3E760DAB-B7EF-45DD-9D23-6BDA0B37538C
