我需要将日志从C#追加到DataLake第2代的blob存储中的Auditlog.csv文件

dotnet add package Microsoft.Azure.Storage.Blob
dotnet add package Microsoft.Azure.Storage.Common

using System;
using System.IO;
using Microsoft.Azure.Storage;
using Microsoft.Azure.Storage.Blob;

class Program
{
    static void Main(string[] args)
    {
        // 连接字符串
        string connectionString = "YourConnectionStringHere";
        // 存储账户名称
        string storageAccountName = "YourStorageAccountName";
        // 容器名称
        string containerName = "YourContainerName";
        // Blob名称
        string blobName = "Auditlog.csv";

        // 创建CloudBlobClient
        CloudBlobClient blobClient = CloudStorageAccount.Parse(connectionString).CreateCloudBlobClient();
        // 获取容器
        CloudBlobContainer container = blobClient.GetContainerReference(containerName);
        // 获取Blob
        CloudBlockBlob blockBlob = container.GetBlockBlobReference(blobName);

        // 日志内容
        string logEntry = $"{DateTime.UtcNow}: Your log message here\n";

        // 追加日志到Blob
        using (var stream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(logEntry)))
        {
            blockBlob.UploadFromStream(stream, accessCondition: null, options: null, operationContext: null);
        }

        Console.WriteLine("Log entry appended successfully.");
    }
}
