在azure文件存储上创建文件

Question

我在Azure中创建了文件存储，可以访问它并验证目录是否存在。如何在云目录中创建文件并写入？

一般信息，如何使用Azure文件存储：https://docs.microsoft.com/en-us/azure/storage/files/storage-dotnet-how-to-use-files如何创建文件并添加一些文本：https://www.youtube.com/watch?v=HnkqqLOOnR4

// Create a CloudFileClient object for credentialed access to Azure Files.
CloudFileClient fileClient = storageAccount.CreateCloudFileClient();

// Get a reference to the file share we created previously.
CloudFileShare share = fileClient.GetShareReference("logs");

// Ensure that the share exists.
if (share.Exists())
{
    // Get a reference to the root directory for the share.
    CloudFileDirectory rootDir = share.GetRootDirectoryReference();

    // Get a reference to the directory we created previously.
    CloudFileDirectory sampleDir = rootDir.GetDirectoryReference("CustomLogs");

    // Ensure that the directory exists.
    if (sampleDir.Exists())
    {
        // Get a reference to the file we created previously.
        CloudFile file = sampleDir.GetFileReference("Log1.txt");

        // Ensure that the file exists.
        if (file.Exists())
        {
            // Write the contents of the file to the console window.
            Console.WriteLine(file.DownloadTextAsync().Result);
        }
    }
}

如果您正在寻找一个在C＃中将文件上传到Azure容器的解决方案，这里有一个我用作将文件上传到Azure的实用程序的函数

public static string UploadBlob(string blobContainerName, string key, Stream sourceStrem, string contentType)
{
    //getting the storage account
    string uri = null;
    try
    {
        blobContainerName = blobContainerName.ToLowerInvariant();
        string azureStorageAccountConnection =
            ConfigurationManager.ConnectionStrings["AzureStorageAccount"].ConnectionString;
        CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(azureStorageAccountConnection);
        CloudBlobClient cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient();

        CloudBlobContainer container = cloudBlobClient.GetContainerReference(blobContainerName);
        container.CreateIfNotExists();

        CloudBlockBlob blob = container.GetBlockBlobReference(key);
        blob.Properties.ContentType = contentType;

        blob.UploadFromStream(sourceStrem);
        uri = blob.Uri.ToString();
    }
    catch (Exception exception)
    {
        if (_logger.IsErrorEnabled)
            _logger.Error(exception.Message, exception);
    }
    return uri;
}

其中blobContainerName是Azure上的容器，key是要存储此blob的文件的名称，第三个参数是文件流，最后一个是内容类型。

希望能帮助到你
