About the code

Before you build the project, make sure you have installed WindowsAzure.Storage package in the project.
The following steps can help you with the installation:

1. Open the solution CSWebAppAzureExcelImportExport.sln.
2. Right click the project and select [Manage NuGet Packages...].
3. Search WindowsAzure.Storage at the Browse tab page. Find the right package and then install it.

You also need to set your Azure information in Helper.cs file:

StorageCredentials cred = new StorageCredentials("[Your storage account name]", "[Your storage account key]");
CloudBlobContainer container = new CloudBlobContainer(new Uri("http://[Your storage account name].blob.core.windows.net/[Your container name] /"), cred);
string connectionStr = "Azure SQL Server Connection String";

Run CreateTable.sql in the SQLScripts folder on your Azure SQL Server DB to create test table and test data, or you can set your data table info first in Helper.cs file if you want to test your own data:

List<string> columns = new List<string>() { "{column1}", "{column2}", "{column3}"};
string tableName = "{table name}";
