将 Azure blob 存储与 .NET 结合使用

Question

Hi I am trying to learn how to work with Azure and .Net .

I built a simple "Hello World" webApp and created a Blob Storage with a table that has 3 email addresses (the webApp and the blob storage are under the same subscription of course)

All I want to do is to show this 3 email addresses when I run the website. ie take this list of addresses from the table in the blob storage and render it over the website.

I have no idea where to start and the Microsoft tutorials did not help much.

Inside my solution explorer under the WebApp, there is a folder "Controllers". My intuition is to open a new class there but again I have no clue of how to start.

Answer 1

It's very simple if you follow this doc .

I have a demo as below:

1.In visual studio -> Nuget Package Manager, install the latest version of WindowsAzure.ConfigurationManager and WindowsAzure.Storage

2.In the web.config -> appsettings node, add <add key="StorageConnectionString" value="your storage account string" /> :

3.In your asp.net web project, add a custom class derived from TableEntity:

public class CustomerEntity : TableEntity
{
    public CustomerEntity(string lastName, string firstName)
    {
        this.PartitionKey = lastName;
        this.RowKey = firstName;
    }

    public CustomerEntity() { }

    public string Email { get; set; }

    public string PhoneNumber { get; set; }
}

4.Then in your controller, add the following code(I add the code in Contact method):

       using System.Web.Mvc;

       using Microsoft.Azure;

       using Microsoft.WindowsAzure.Storage;

       using Microsoft.WindowsAzure.Storage.Table; 

        public ActionResult Contact()
        {
            //define the emails to output in web page
            string emails = "";

            // Retrieve the storage account from the connection string.

            CloudStorageAccount storageAccount = CloudStorageAccount.Parse(

                CloudConfigurationManager.GetSetting("StorageConnectionString"));

            // Create the table client.

            CloudTableClient tableClient = storageAccount.CreateCloudTableClient();

            // Create the CloudTable object that represents the "people" table.

            CloudTable table = tableClient.GetTableReference("people");

            TableQuery<CustomerEntity> query = new TableQuery<CustomerEntity>();

            foreach (CustomerEntity entity in table.ExecuteQuery(query))
            {

                    emails += entity.Email+";";

            }

            ViewBag.Message = "Your contact page."+emails;

            return View();
        }

5. My azure table and the test result:

all the email addresses are displayed in web page:
