List blob versions

Is there a way to list all of a specific blob's versions without having to list all the blobs and all their versions within a container?

If I have a pointer to a blob, can I get a list of that blob's versions?

    If you are using the .net SDK please see if this code might work for your use case:

    public static class BlobContainerClientExtensions  
        {  
            public static async IAsyncEnumerable<string?> GetVersions(this BlobContainerClient blobContainerClient, string blobName)  
            {  
                var resultSegment = blobContainerClient.GetBlobsAsync(BlobTraits.None, BlobStates.Version, prefix: blobName).AsPages(default, 100);  
                await foreach (var blobPage in resultSegment)  
                    foreach (var blobItem in blobPage.Values)  
                        yield return blobItem.VersionId;  
            }  
        }  
    

    The easiest way to view the versions of an individual blob would be to use Storage Explorer. To view a blob's versions, select the blob you want to view versions for and select Manage History → Manage Versions from either the toolbar or the context menu.

    Hope this helps. Let us know if you have further questions or issues.
