MS Azure : Not Able To Copy Azure Cloud File To Another Directory

Question

I am trying to copy a Cloud File from one directory to another, within same File-Share account but facing issue.

Code:

Below is the code I am using, following article ( https://learn.microsoft.com/en-us/azure/storage/files/storage-dotnet-how-to-use-files#copy-files )

public bool ArchiveTheFile(string filename)
    {
        bool fileCopied = false;
        try
        {
            var fileshare = ResolveCloudFileShare();
            if (fileshare.Exists())
            {
                CloudFileDirectory rootDir = fileshare.GetRootDirectoryReference();
                CloudFileDirectory dirSource = rootDir.GetDirectoryReference(ConfigurationManager.AppSettings["Azure.Storage.FileShare.Source"]);
                CloudFileDirectory dirArchive = rootDir.GetDirectoryReference(ConfigurationManager.AppSettings["Azure.Storage.FileShare.Destination"]);

                // Ensure that the directory exists.
                if (dirSource.Exists())
                {
                    // Get a reference to the file we created previously.
                    CloudFile sourceFile = dirSource.GetFileReference(filename);

                    // Ensure that the file exists.
                    if (sourceFile.Exists())
                    {
                        // Ensure that the directory exists.
                        if (dirArchive.Exists())
                        {
                            // Get a reference to the destination file.
                            CloudFile destFile = dirArchive.GetFileReference(filename);
                            destFile.StartCopy(sourceFile);fileCopied =true;
                        }
                    }
                }
            }
        }
        catch (Exception ex)
        {
        }
        return fileCopied ;
    }

Below is the error :

Not able to use StartCopy() method of CloudFile class

1. Screenshot of error :

Object returning by GetFileReference() do not have StartCopy() method :

2. Error Message :

'CloudFile' does not contain a definition for 'StartCopy' and no extension method 'StartCopy' accepting a first argument of type 'CloudFile' could be found (are you missing a using directive or an assembly reference?

Please Note: I am already using below two assembly reference:

using Microsoft.WindowsAzure.Storage;

using Microsoft.WindowsAzure.Storage.File;

Answer 1

Update your Microsoft.WindowsAzure.Storage package to latest version or at least 5.0.2. StartCopy for CloudFile is not supported until version 5.0.2.
