C# 如何使用c发送microsoft botframework sdk v4中本地文件夹中的图像#

我使用Microsoft Botframework C#SDK V4创建了一个机器人，它运行良好。现在我想给机器人添加一些图像。我正在使用卡片，但卡片只获取图像的url。我想发送本地文件夹中的图像。我怎样才能让它工作

我已经在15.0 github repo（）上尝试过了。当我在处理附件github repo时使用了精确的代码，我得到了以下内联附件的异常stacktrace

如何解决此问题？？？

此示例演示如何读取本地文件，并将其附加为base64编码图像：

reply.Attachments = new List<Attachment>() { GetInlineAttachment() };

private static Attachment GetInlineAttachment()
{
    var imagePath = Path.Combine(Environment.CurrentDirectory, @"Resources\architecture-resize.png");
    var imageData = Convert.ToBase64String(File.ReadAllBytes(imagePath));

    return new Attachment
    {
        Name = @"Resources\architecture-resize.png",
        ContentType = "image/png",
        ContentUrl = $"data:image/png;base64,{imageData}",
    };
}

当我尝试使用第一个代码段时，它会向我显示“抱歉，它看起来出了问题”，即使我在我的项目资源文件夹中添加了该图像。您能否建议我如何使用c#在sdk v4中获取异常堆栈跟踪以及默认错误消息。请确保已将本地文件设置为“复制到输出目录”。您可以通过添加OnTurnError来获取异常堆栈跟踪。您还可以在本地进行调试：感谢您的响应，现在我正在获取堆栈跟踪以及默认错误消息。当我在将本地文件设置为“复制到输出目录”后尝试使用第一个代码段时，它仍然不起作用。当我尝试使用“http url”时，它可以工作，但当我尝试使用本地路径时，它不会显示图像。我还需要改变什么吗。

private async Task SendFile(ITurnContext turnContext)
{
    var webRoot = _env.ContentRootPath;
    var imagePath = System.IO.Path.Combine(webRoot, "Resources", "BotFrameworkDiagram.png");
    var connector = turnContext.TurnState.GetValueOrDefault("Microsoft.Bot.Connector.IConnectorClient") as ConnectorClient;

    var attachments = new Attachments(connector);
    var response = await attachments.Client.Conversations.UploadAttachmentAsync(
        turnContext.Activity.Conversation.Id,
        new AttachmentData
        {
            Name = "BotFrameworkDiagram.png",
            OriginalBase64 = File.ReadAllBytes(imagePath),
            Type = "image/png"
        });

    var attachmentUri = attachments.GetAttachmentUri(response.Id);

    var attachment = new Attachment
    {
        Name = "BotFrameworkDiagram.png",
        ContentType = "image/png",
        ContentUrl = attachmentUri
    };

    var reply = turnContext.Activity.CreateReply();
    reply.Attachments.Add(attachment);
    await turnContext.SendActivityAsync(reply);   
}
