在将电子表格导出为CSV格式时保留空行的分隔符
Aspose.Cells 提供在转换电子表格到 CSV 格式时保留换行符的能力。为此，你可以使用 TxtSaveOptions 的 TxtSaveOptions.keepSeparatorsForBlankRow 属性。TxtSaveOptions.keepSeparatorsForBlankRow 是一个布尔属性。要在转换 Excel 文件到 CSV 时保留空白行的分隔符，请将 TxtSaveOptions.keepSeparatorsForBlankRow 属性设置为 true。
以下示例代码加载 源Excel文件，将 TxtSaveOptions.keepSeparatorsForBlankRow 属性设置为 true 并保存为 output.csv。屏幕截图显示源Excel文件、转换成csv时生成的默认输出以及设置 TxtSaveOptions.keepSeparatorsForBlankRow 为 true 时的输出的对比。
