我是靠谱客的博主紧张乌冬面，最近开发中收集的这篇文章主要介绍Azure文件上传下载删除，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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);
