如何让用户在botframework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; }我希望用户能够在机器人框架中填写表单时包含图像。我将图片字段声明为字节，但在上传图片时不起作用。这有可能实现吗？如果是，请有人向我介绍如何去做吗？谢谢

Answer 1

SDK Repository 中有一个示例，用于执行此操作。

从示例中看来，您需要使用该AwaitableAttachment类型，请查看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;
