excel - 为什么在此v​​ba脚本中出现不匹配错误？

Question

在“EmailItem.To = Str(Sheet4.Cells(1，2))”行上，当我尝试运行它时，出现不匹配错误，我该如何解决？
这是代码

Sub SendEmail_Example1()

Dim EmailApp As Outlook.Application
Dim Source As String
Set EmailApp = New Outlook.Application

Dim EmailItem As Outlook.MailItem
Set EmailItem = EmailApp.CreateItem(olMailItem)

EmailItem.To = Str(Sheet4.Cells(1, 2))
EmailItem.CC = "marcusburr@gmail.com"
EmailItem.Subject = "Test Email From Excel VBA"
EmailItem.HTMLBody = "Hi," & vbNewLine & vbNewLine & "This is my first email from Excel" & _
vbNewLine & vbNewLine & _
"Regards," & vbNewLine & _
"VBA Coder"


EmailItem.Send

End Sub

Answer 1

EmailItem.To = Str(Sheet4.Cells(1, 2))

Str需要一个数字参数。您在考虑 CStr()吗？
