Connection String to an Azure Cloud Storage Account

Notating this because it's a top Google hit and the information is no longer current.

You can configure CloudStorageAccount via a connection string passed to FromConfigurationSetting().

You build a configuration string per below:https://docs.microsoft.com/en-gb/azure/storage/common/storage-configure-connection-string

There's also a helper in the IDE if you right click on the Role.

Reference: Azure Documentation

Connection string to an Azure storage account:

DefaultEndpointsProtocol=[http|https];AccountName=myAccountName;AccountKey=myAccountKey

example:

DefaultEndpointsProtocol=https;AccountName=storagesample;AccountKey=<account-key>

Connection string to the storage emulator:

config.xml

<appSettings>      <add key="StorageConnectionString" value="UseDevelopmentStorage=true" />    </appSettings>DefaultEndpointsProtocol=http;AccountName=testacc1;AccountKey=1gy3lpE7Du1j5ljKiupgKzywSw2isjsdfdsfsdfsdsgfsgfdgfdgfd/YThisv/OVVLfIOv9kQ==;BlobEndpoint=http://127.0.0.1:8440/testacc1;TableEndpoint=http://127.0.0.1:8440/testacc1;QueueEndpoint=http://127.0.0.1:8440/testacc1;

Ex:

 <connectionStrings>          <add name="AzureStorageAccount" connectionString="DefaultEndpointsProtocol=https;AccountName=testdata;Accoun‌​tKey=1gy3lpE7Du1j5ljKiupgKzywSw2isjsdfdsfsdfsdsgfsgfdgfdgfd/YThisv/OVVLfIOv9kQ==;"/>    </connectionStrings>

But sometimes it won't work and will through the error

An unhandled exception of type 'System.FormatException' occurred in Microsoft.WindowsAzure.Storage.dllAdditional information: No valid combination of account information found.

then please try with below code: tested and working 100%

var accountName = "test2rdsfdg462";var keyValue = "1gy3lpE7Du1j5ljKiupgKzywSfsdfdsfsdfsdfsdfsdfsdqGxd7/YThisv/OVVLfIOv9kQ==";var useHttps = true;var connValid = true;var storageCredentials = new StorageCredentials(accountName, keyValue);var storageAccount = new CloudStorageAccount(storageCredentials, useHttps);var conString = storageAccount.ToString(connValid);CloudStorageAccount sa = CloudStorageAccount.Parse(connString);

If you look in the Azure portal under the storage account in question, and look in the "Access Keys" item in the left-side nav, there it shows you the two provided keys and the entire connection string needed to access the storage account.
