Azure文件上传下载删除(D365可以直接用)

1.将文件上传到Azure的特定容器下；

下面以将文件上传到Azure的Container下。

using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Auth;
using Microsoft.WindowsAzure.Storage.Blob;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

namespace AzureCall
{
    class Program
    {
        static void Main(string[] args)
        {
            var fileName = Guid.NewGuid() + ".CSV";
            byte[] byteArray = new byte[10000];

            //Make sure a file was posted
            string contentType = "application/octet-stream";
　　　　
            Stream stream = new MemoryStream(byteArray);

           //这里文件流如果不知道如何获取，可以看下我的关于上传下载工具的文档。

            string accountName = "存储账户";
            string accessKey = "密码";
            string containerName = "容器名称";

            // BLOB credential
            var credential = new StorageCredentials(accountName, accessKey);
            var storageAccount = new CloudStorageAccount(credential, true);

            // BLOB client
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
            CloudBlobContainer container = blobClient.GetContainerReference(containerName);

            container.CreateIfNotExistsAsync();

            // Get csv file reference
            CloudBlockBlob cloudBlockBlob = container.GetBlockBlobReference(fileName);

            // Create or overwrite the blob with contents from a local file
            cloudBlockBlob.Properties.ContentType = contentType;
            cloudBlockBlob.UploadFromStream(stream);
        }
    }
}

2.删除Azure上的文件；

 

string accountName = "存储账户";
string accessKey = "密码";
string containerName = "容器名称";
// BLOB credential
var credential = new StorageCredentials(accountName, accessKey);
var storageAccount = new CloudStorageAccount(credential, true);
// BLOB client
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
CloudBlobContainer container = blobClient.GetContainerReference(containerName);
// Retrieve reference to a blob named
CloudBlockBlob blob = container.GetBlockBlobReference(fileName);
if (blob.Exists())
blob.DeleteAsync();

 

3.从Azure的特定容器下载文件；

 

string accountName = "存储账户";
string accessKey = "密码";
string containerName = "容器名称";
// BLOB credential
var credential = new StorageCredentials(accountName, accessKey);
var storageAccount = new CloudStorageAccount(credential, true);
// BLOB client
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
CloudBlobContainer container = blobClient.GetContainerReference(containerName);

// Get csv file reference

CloudBlockBlob cloudBlockBlob = container.GetBlockBlobReference(fileName);

string filePath = @"C:\Alfred\";
if (!Directory.Exists(filePath))
{
       Directory.CreateDirectory(filePath);
}

cloudBlockBlob.DownloadToFile(filePath, FileMode.OpenOrCreate);
