Microsoft has a nice guide called Connect an app to Azure Storage that goes through everything you need.

Description:

Create a simple application and add configuration, client library references, and code to connect it to Azure Storage.

https://learn.microsoft.com/en-us/learn/modules/connect-an-app-to-azure-storage/

Step 7 there is Connect to your Azure storage account

Connection strings example:

DefaultEndpointsProtocol=https;AccountName={your-storage};
   AccountKey={your-access-key};
   EndpointSuffix=core.windows.net

The REST endpoint is a combination of your storage account name, the data type, and a known domain. For example:

Data type Example endpoint
Blobs https://[name].blob.core.windows.net/
Queues https://[name].queue.core.windows.net/
Table https://[name].table.core.windows.net/
Files https://[name].file.core.windows.net/

https://learn.microsoft.com/en-us/learn/modules/connect-an-app-to-azure-storage/7-connect-to-your-azure-storage-account

To get a connection string I usually follow @user3459730 example and copy it from Azure Portal. Go to Storage account -> Access keys, click on Show keys and copy the Connection string.

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.

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.dll

Additional 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);

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://learn.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.
