隐藏通过电子邮件c＃发送的附件中的文件路径

Question

以下是代码：

message.Attachments.Add(new Attachment("C:/Program Files (x86)/Software/Extraction/INVOICE_AMOUNT_VS_ORDER_AMOUNT.xlsx"));

显示为＆＃34; / Program Files（x86）/Software/Extraction/INVOICE_AMOUNT_VS_ORDER_AMOUNT.xlsx"在发送的邮件中。

我只需要接收器查看文件名。

Answer 1

我认为你需要这样的东西：

var path = "C:/Program Files (x86)/Software/Extraction/INVOICE_AMOUNT_VS_ORDER_AMOUNT.xlsx";
message.Attachments.Add(new Attachment(Path.GetFileName(path).ToString()));

Answer 2

这是因为您使用了错误的斜杠（路径分隔符）。

改变这个：

message.Attachments.Add(new Attachment("C:/Program Files (x86)/Software/Extraction/INVOICE_AMOUNT_VS_ORDER_AMOUNT.xlsx"));

对此：

message.Attachments.Add(new Attachment(@"C:\Program Files (x86)\Software\Extraction\INVOICE_AMOUNT_VS_ORDER_AMOUNT.xlsx"));
