如何从amazontextract响应中解析键值对和表数据？

Question

我正在使用.Net使用amazontextract提取键值对和表，如何从analysedocumentrequest响应中获得的键值对和表中动态提取数据？下面的代码我将块作为静态值传递。

    AmazonTextractClient Atc = new AmazonTextractClient(credentials, config);
                Document MyDocument;
                using (Image image = Image.FromFile(imagePath))
                {
                    using (MemoryStream m = new MemoryStream())
                    {
                        image.Save(m, image.RawFormat);
                        MyDocument = new Document()
                        {
                            Bytes = m
                        };
                    }
                }
                var DocRequest = new AnalyzeDocumentRequest()
                {
                    Document = MyDocument,
                    FeatureTypes = new List<string> { FeatureType.FORMS, FeatureType.TABLES }
                };
                var response = Atc.AnalyzeDocument(DocRequest);
 var reg = response.Blocks.ElementAt(20);
                var result= reg.Relationships.Select(r=> r.Ids).ToList();
                for (int i = 0; i < result.Count; i++)
                {
                foreach(var str in result[i])
                    {
                        int red = response.Blocks.Count;
                        for (int j = 1; j < red; j++)
                        {

                            if (response.Blocks[j].Id == str)
                            {
                                textValue = textValue + " " + response.Blocks[j].Text;
                                break;
                            }
                        }
                    }
                }
