Get content of new file type field in plugin

(0) ShareShare
ReportReport
Posted on by Mikhail.T 12

Good day community,

Is there a way to get content of the new file type in a plugin? 

https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/file-attributes 

I see we can get content by web API. But in a plugin, I can only see a file name and some GUID. 

Any suggestions? 

Thanks,

Mikhail.

    I see an example using C#: docs.microsoft.com/.../file-attributes

    Attributes: docs.microsoft.com/.../microsoft.xrm.sdk.metadata.fileattributemetadata

    So, what I would do is register the plugin in the post operation and then use the soap request to retrieve the file.

    Retrieve file: docs.microsoft.com/.../file-attributes

    Regards,

    Good day, Johao,

    Many thanks for your reply!

    C# example shows using web API. For using web API from plugin I need to create application in Azure for correct authentication and this way not looks good for me.

    Can you explain what do you mean by SOAP request from plugin?

    Because what I know that is SDK doing SOAP request behind the scene and in response there is no actual content of the file(checked that in Fidller from a console app).  

    In MS article we can find - File attributes are supported in SdkClientVersion 9.0.45.329 or greater and Web API version 9.1 or greater.

    But latest SDK for now has version -  9.0.45.2156. I tried to send version that was mentioned in article but it gave nothing. 

    Mikhail.

    For those who looking for the same.

    First we requesting FileContinuationToken and then calling DownloadBlockRequest that will return byte array data for us. 

    InitializeFileBlocksDownloadRequest ifbdRequest = new InitializeFileBlocksDownloadRequest
{
    Target = new EntityReference("nameoftheentitywithfiletype", new Guid("2bffcfbb-dbae-ea11-a812-000d3abaac27")),
    FileAttributeName = "filefieldname"
};

InitializeFileBlocksDownloadResponse ifbdResponse = (InitializeFileBlocksDownloadResponse)_service.Execute(ifbdRequest);

DownloadBlockRequest dbRequest = new DownloadBlockRequest
{
    FileContinuationToken = ifbdResponse.FileContinuationToken
};

var resdbResponsep = (DownloadBlockResponse)_service.Execute(dbRequest);

    When I add this code to my plugin project, it builds fine but when I use the Plugin Registration Tool to debug by code I get an error:

    Could not load type 'Microsoft.Crm.Sdk.Messages.InitializeFileBlocksDownloadRequest' from assembly 'Microsoft.Crm.Sdk.Proxy'

    Did you have the same issue? If so, how did you work around that?
