推荐答案
尝试一下
Try out this
Subject = "Visitor Appointment"
Message = "<HTML><BODY>" _
& "Dear Sir,<BR>" _
& "<BR>" _
& "Visitor want to meet you<BR>" _
& "<B>Visitor Name: </B>" & EmployeetoMeet.ToString() & "<BR>" _
& "<B>Visitor Contact No: </B>" & EmpMobileNo.ToString() & "<BR>" _
& "<BR>" _
& "Thanks & Regards,<BR>" _
& "iSpirit Tech<BR>" _
& "</BODY></HTML>"
您正在用VB编写代码，因此对于串联字符串，应使用& 而不是 +
希望对您有所帮助.
You are writing code in VB, so for concatenation string you should use & and NOT +
Hope it helps.
我猜这是这段代码:
I''m guessing it''s this bit of code:
& "<B>Visitor Name: </B>" & +EmployeetoMeet.ToString() + +"<BR>" _ & "<B>Visitor Contact No: </B>" & +EmpMobileNo.ToString() + "<BR>" _
有时您正在使用&进行连接，但是您那里有一堆+号....它可能试图将字符串转换为双精度，因为它认为您想执行数学加法运算.除去EmployeetoMeet.ToString() 之前的+号，并将之后的+号转换为单个&.
Sometimes you are using & to concat but you have a bunch of + signs in there....it''s probably trying to convert the string to a double because it thinks you want to perform a mathematical addition. Get rid of the + signs before EmployeetoMeet.ToString() and convert the + signs after into a single &.
