小革3602025-05-23 17:16

EmailSenderHtmlV1 是读取配置文件《批量发送邮件.xlsx》，配置sheet获取 发件人邮箱 邮箱账号 口令，发送excel数据sheet获取收件人邮箱 抄送人邮箱 邮件标题 第N行开始(N>=1,N=0默认表头) 第M行结束(M>=1,M=0默认表头) 附件文件夹 附件名，同时发送excel数据内容详情sheet配合发送excel数据sheet的第N和第M行信息，获取excel内容。

EmailSenderV1是读取配置文件《批量发送邮件.xlsx》，配置sheet获取 发件人邮箱 邮箱账号 口令，发送数据sheet 获取 收件人邮箱 抄送人邮箱 邮件标题 邮件内容 附件文件夹 , 附件名。

ExcelToHtmlConverter 是将excel数据内容详情sheet内单元格信息转换为html格式，作为邮件内容发送。
