如何使用户在僵尸框架中发送图像附件

Question

[Serializable]
public class VehicleForm
{
    [Prompt("When did this happen")]
    public DateTime LossDate { get; set; }

    [Prompt("Please upload proof image")]
    public byte Picture { get; set; }

我希望用户能够包括在bot框架中填写表单时的图像。我将图片字段声明为字节，但上传图像时不起作用。这是可能的吗？如果是的话，谁能告诉我怎么做呢？谢谢

有一个SDK库中的示例来做这件事。

从示例中可以看出，您需要使用AwaitableAttachment类型，查看一下ImagesForm

// Attachment field has no validation - any attachment would work
public AwaitableAttachment BestImage;

// Attachment field is optional - validation is done through AttachmentContentTypeValidator usage
[Optional]
[AttachmentContentTypeValidator(ContentType = "png")]
public AwaitableAttachment SecondaryImage;
