[AI] 呼叫Azure Document Intelligence解析扫描文件

C#直接取栏位值

直接取栏位值写法

using Azure;
using Azure.AI.DocumentIntelligence;

string endpoint = @"https://名称.cognitiveservices.azure.com/";
string key = "xxxxxx";
string modeid = "模型名";
AzureKeyCredential credential = new AzureKeyCredential(key);

// 读取文件并转换为 BinaryData
string filePath = @"D:\台\AI\湾\已\独.pdf";
BinaryData binaryData = new BinaryData(File.ReadAllBytes(filePath));
//传入Uri或BinaryData皆可
Operation<AnalyzeResult> operation = await client.AnalyzeDocumentAsync(WaitUntil.Completed, modeid, binaryData);
AnalyzeResult result = operation.Value;
StringBuilder sb = new StringBuilder();
Dictionary<string, string> dbVal = new Dictionary<string, string>();//记栏位用

        }
        else if (field.ValueSelectionMark == DocumentSelectionMarkState.Selected)//假设栏位只有字串或checkBox二种
