store json on blob storage using Azure function c#

Question

I want to store json on blob storage using azure function c#

For example my json is :

{
"a":"a",
"b":"b",
"c":[{"c1":"c1"},{"c2":"c2"}]
}

I would like to write to the file or even read from the file.

Are there any samples of writing and reading to files using Azure functions c#?

Thank You

There's good documentation on Microsoft for it such as learn.microsoft.com/en-us/azure/storage/blobs/… — Tom John

Have a look at the CloudStorageAccount class:

https://learn.microsoft.com/en-us/dotnet/api/microsoft.azure.storage.cloudstorageaccount?view=azure-dotnet

Using these you can create a CloudBlobClient and CloudBlobContainer. Then the CloudBlockBlob class:

https://docs.azure.cn/zh-cn/dotnet/api/microsoft.windowsazure.storage.blob.cloudblockblob?view=azure-dotnet

Use the CloudBlockBlob class:

CloudBlockBlob.UploadFromByteArray(...) to Upload, and cloudBlockBlob.DownloadToByteArray(...) to Download your file.

Both links are broken mate

Is that a down vote because links to a third party site from over a year ago are no longer valid? A simple google of the 2 classes documented gives the current documentation.

Maybe next time just propose an edit with the revised URLS? They are only links to the official microsoft documentation that has clearly changed structure.
