C#winform NPIO生成Excel包括复制上传图片等
XSSFWorkbook在复制单元格时可以处理图片的复制和插入。你可以使用以下步骤来实现:
1. 首先,创建一个新的XSSFWorkbook对象,并加载你要复制的Excel文件:
```java
XSSFWorkbook workbook = new XSSFWorkbook(new FileInputStream("原始文件.xlsx"));
```
2. 然后,获取要复制的工作表和单元格:
```java
XSSFSheet sheet = workbook.getSheet("工作表名称");
XSSFCell sourceCell = sheet.getRow(0).getCell(0);
```
3. 接下来,创建一个新的工作表和单元格,并将源单元格的值和样式复制到新单元格:
```java
XSSFSheet newSheet = workbook.createSheet("新工作表名称");
XSSFCell newCell = newSheet.createRow(0).createCell(0);
newCell.setCellValue(sourceCell.getStringCellValue());
newCell.setCellStyle(sourceCell.getCellStyle());
```
4. 如果源单元格包含图片,你可以使用以下代码来复制和插入图片:
```java
if (sourceCell.getCellType() == CellType.STRING && sourceCell.getStringCellValue().startsWith("image:")) {
String imagePath = sourceCell.getStringCellValue().substring(6);
InputStream imageStream = new FileInputStream(imagePath);
byte[] imageBytes = IOUtils.toByteArray(imageStream);
int pictureIndex = workbook.addPicture(imageBytes, Workbook.PICTURE_TYPE_PNG);
CreationHelper helper = workbook.getCreationHelper();
Drawing drawing = newSheet.createDrawingPatriarch();
ClientAnchor anchor = helper.createClientAnchor();
anchor.setCol1(newCell.getColumnIndex());
anchor.setRow1(newCell.getRowIndex());
Picture picture = drawing.createPicture(anchor, pictureIndex);
picture.resize();
}
```
5. 最后,保存并关闭工作簿:
```java
FileOutputStream outputStream = new FileOutputStream("复制后的文件.xlsx");
workbook.write(outputStream);
workbook.close();
outputStream.close();
```
这样,你就可以使用XSSFWorkbook来复制单元格,并处理图片的复制和插入了。
