如何使用 C# 和 .NET Core 3.x 管理 AWS Cognito 用户池中的用户？在文档中找不到有关它的任何内容。

此问题与以下内容有关：ASP.NET Core Web API上传和下载文件

首先，我要感谢Powel Gerr，他帮助我理解了他的帖子（http://weblogs.thinktecture.com/pawel/2017/03/aspnet-core-webapi-performance.html）中的一些细微差别。我还有一个要解决的问题。

我的场景假设我们有一个.NET Core控制台应用程序：

private static void Main(string[] args)
{
    Console.WriteLine($"Test starts at {DateTime.Now.ToString("o")}");
    FileStream fileStream = new FileStream(@"C:\Windows10Upgrade\Windows10UpgraderApp.exe", FileMode.Open);

    MyFile vFile = new MyFile()
    {
        Lenght = 0,
        Path = "https://c2calrsbackup.blob.core.windows.net/containername/Windows10UpgraderApp.exe",
        RelativePath = "Windows10UpgraderApp.exe"
    };
    Stream uploadStream = GetUploadStream(vFile).GetAwaiter().GetResult();

    fileStream.CopyTo(uploadStream);

    Console.WriteLine($"Test ends at {DateTime.Now.ToString("o")}");
    Console.Write("Press any key to exit...");
    Console.ReadKey();
}

private static async Task<Stream> GetUploadStream(MyFile myFile)
{
    Stream stream = null;

    try
    {
        using (HttpClient httpClient = new HttpClient())
        {
            httpClient.BaseAddress …

我有一点问题。我的环境是.NET Core 2.1中的控制台应用程序。

看下面的代码：

private static void Main(string[] args)
{
    try
    {
        Console.WriteLine($"Test starts: {DateTime.Now.ToString("o")}");

        string connectionString = "[My connection string]";
        string containerName = "mycontainer";

        CloudStorageAccount account = CloudStorageAccount.Parse(connectionString);
        CloudBlobClient serviceClient = account.CreateCloudBlobClient();
        CloudBlobContainer container = serviceClient.GetContainerReference(containerName);

        container.CreateIfNotExistsAsync().Wait();

        CloudBlockBlob cloudBlockBlob = container.GetBlockBlobReference($"{containerName}/Test.txt");
        CloudBlobStream cloudBlobStream = cloudBlockBlob.OpenWriteAsync().Result;

        string json = JsonConvert.SerializeObject(cloudBlobStream);

        Console.WriteLine($"Test ends: {DateTime.Now.ToString("o")}");
    }
    catch (Exception e)
    {
        string stackTrace = e.StackTrace;

        while(e != null)
        {
            Console.WriteLine(e.Message);
            e = e.InnerException;
        }
        Console.WriteLine(stackTrace);
    }
    Console.Write("Press any key to exit...");
    Console.ReadKey();
} …
