I've got a text file I need to append data to daily with a timer Azure Function. The text file is a comma separated file. I've created my CloudBlobClient and knew how to make my Shared Access Policy and Token. I just don't know how to use this to upload. I only know how to get an access URI from the tutorial I'm working with.

您可以尝试使用针对附加操作优化的附加blob.根据您的描述，您知道如何获取 SAS URI ，因此您可以使用SAS URI创建对附加Blob的引用，并将文件附加到附加Blob，以下代码供您参考.

You can try to use append blob that is optimized for append operations. According to your description, you know how to get SAS URI, so you can use SAS URI to create a reference to an append blob, and append a file to an append blob, the following code is for your reference.

CloudAppendBlob appendBlob = new CloudAppendBlob(new Uri("https://{storage_account}.blob.core.windows.net/{your_container}/append-blob.log?st=2017-09-25T02%3A10%3A00Z&se=2017-09-27T02%3A10%3A00Z&sp=rwl&sv=2015-04-05&sr=b&sig=d0MENO44GjtBLf7L8U%2B%2F2nGwPAayjiVSSHaKJgEkmIs%3D"));


appendBlob.AppendFromFile("{filepath}\source.txt");
