+### Query_SOP SaveToImage 异常修复
+- 问题：`sheet.SaveToImage(filePath)` 抛出 `ArgumentOutOfRangeException: Index is out of range`
+- 根因分析：
+  1. try-catch 被注释掉（uploadfile + SaveFileToJPG + SaveFileToPDF 三处），异常直接弹出
+  2. CreateEmptySheet + CopyFrom 可能未正确复制 sheet 内部状态（如 AllocatedRange），导致 SaveToImage 渲染时索引越界
+  3. 重试循环内重复执行 `sheet.Pictures.Add`，每次 retry 都给同一 sheet 添加电子受控章和签名图片，图片集合索引冲突
+- 修复：
+  1. 恢复全部 3 处 try-catch
+  2. 去掉 CreateEmptySheet + CopyFrom，直接传 `workbook.Worksheets[i]` 给 SaveFileToJPG/SaveFileToPDF（串行模式下直接修改原 sheet 安全）
+  3. 图片添加（Pictures.Add）移到重试循环外，只添加一次
+  4. SaveFileToJPG/SaveFileToPDF 中目录创建和文件路径也移到循环外，避免重复
+
+### Spire.XLS 依赖 DLL 补充（前次会话遗留）
+- Spire.XLS.dll v8.8.1.6040 依赖 Spire.License v1.3.6.40 和 Spire.Pdf v4.8.3.2040
+- 之前这两个 DLL 缺失导致 TypeInitializationException，用户已手动补充到 bin/Debug
+
+### Query_SOP OutOfMemoryException 最终修复
+- 问题：30个Sheet的Excel文件上传时第一个sheet就OOM，3个Sheet的文件正常
+- 根因：32位x86进程内存上限2GB，30个sheet的workbook加载后已占大量内存，CopyFrom再复制一份+600DPI大位图三者叠加必然超限
+- 3个sheet文件正常的原因：workbook本身小，即使600DPI+CopyFrom也不会超2GB
+- 第一次修复（去掉CopyFrom）反而更糟：直接用原sheet调用SaveToImage时，Spire.XLS内部需要处理整个workbook(30个sheet)的布局上下文，内存爆炸，第一个sheet就OOM
+- 最终修复方案（恢复CopyFrom + 串行 + 低DPI + OOM降级）：
+  1. **恢复CopyFrom**：每个sheet复制到独立Workbook(只有1个sheet)，SaveToImage只处理1个sheet的布局上下文，内存可控
+  2. 串行处理（不并发）：避免DataHelper static连接竞态+Spire.Xls非线程安全
+  3. DPI 600→96：位图内存降为约1/40
+  4. 每个sheet处理完立即 she=null; bw=null + GC.Collect 释放临时workbook
+  5. SaveFileToJPG恢复try-catch，catch(OutOfMemoryException)时降级为SaveToPdf（矢量格式内存极小）
+  6. 图片添加移到重试循环外，避免重复Pictures.Add
+  7. 提取UploadFile/SaveToPdfAndUpload辅助方法消除重复代码
+
+### 索引越界降级修复
+- 问题：恢复CopyFrom后第一个sheet成功，但第二个sheet开始报 `Index is out of range. 参数名：index`
+- 根因：CopyFrom没有完整复制某些sheet的内部状态（AllocatedRange等），SaveToImage渲染时索引越界
+- 修复：把 `catch(OutOfMemoryException)` 扩大为 `catch(Exception)`，任何SaveToImage异常都自动降级为PDF格式
+
+### 最终方案：放弃Spire.XLS，改用Aspose.Cells 18.4重写Query_SOP
+- 用户决定彻底放弃Spire.XLS（OOM+索引越界死循环无法解决），改用项目中已有的Aspose.Cells 18.4.0.0
+- API对照：
+  - 加载文件：`workbook.LoadFromFile(path)` → `new Aspose.Cells.Workbook(path)`
+  - TextBox文本：`tb.RichText.Text` → `tb.Text`
+  - TextBox对齐：`tb.HAlignment = CommentHAlignType.Center` → `tb.TextHorizontalAlignment = TextAlignmentType.Center`
+  - 添加图片：`sheet.Pictures.Add(path)` → `sheet.Pictures.Add(row, col, path)`
+  - 图片列：`pic.LeftColumn = 20` → Add时指定 `col=20`
+  - 图片行偏移：`pic.TopRowOffset = 20` → `pic.UpperDeltaY = 20`
+  - 转图片：`sheet.SaveToImage(path)` → `SheetRender.ToImage(pageIndex, path)` + `ImageOrPrintOptions`
+  - 转PDF：`sheet.SaveToPdf(path)` → 创建独立workbook + `CopyFrom(sheet)` + `Save(path, SaveFormat.Pdf)`
+- csproj删除了Spire.Pdf和Spire.License引用（不再需要）
+- using改为 Aspose.Cells + Aspose.Cells.Drawing + Aspose.Cells.Rendering + System.Drawing.Imaging
+- 功能逻辑保持不变：串行处理 + TextBox放大 + 电子受控章/签名图片 + 内存收集fp_id + 一次性UPDATE
+- 新增UploadFile辅助方法消除重复的上传代码
