【自动化办公】如何快速的去识别PDF多个区域内容，将内容提取出来后保存到Excel表格里面，基于WPF的和腾讯API的详细解决方案

// 示例代码：读取 PDF 文件
private byte[] ReadPdfFile(string filePath)
{
    return File.ReadAllBytes(filePath);
}

using TencentCloud.Common;
using TencentCloud.Common.Profile;
using TencentCloud.Ocr.V20181119;
using TencentCloud.Ocr.V20181119.Models;

private async Task<string> RecognizeText(byte[] imageData, int x, int y, int width, int height)
{
    Credential cred = new Credential
    {
        SecretId = "YOUR_SECRET_ID",
        SecretKey = "YOUR_SECRET_KEY"
    };
    ClientProfile clientProfile = new ClientProfile();
    clientProfile.HttpProfile.Endpoint = "ocr.tencentcloudapi.com";
    OcrClient client = new OcrClient(cred, "", clientProfile);

    // 假设将 PDF 区域转换为图片数据（这里需要实际实现）
    // 以下是示例请求参数，实际需根据转换后的图片数据设置
    GeneralBasicOCRRequest req = new GeneralBasicOCRRequest
    {
        ImageBase64 = Convert.ToBase64String(imageData)
    };

    GeneralBasicOCRResponse resp = await client.GeneralBasicOCR(req);
    return resp.TextDetections;
}

using OfficeOpenXml;

private void SaveToExcel(string[] recognitionResults, string excelFilePath)
{
    using (ExcelPackage package = new ExcelPackage())
    {
        ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("Sheet1");
        for (int i = 0; i < recognitionResults.Length; i++)
        {
            worksheet.Cells[i + 1, 1].Value = recognitionResults[i];
        }
        package.SaveAs(new FileInfo(excelFilePath));
    }
}
