Question

目前，我正在尝试使用VB.NET发送电子邮件。现在，我添加了一个带有此代码的引用:(我添加了占位符）

Module Module1

    Sub Main()
        ' Create an Outlook application.
        Dim oApp As Outlook._Application
        oApp = New Outlook.Application()

        ' Create a new MailItem.
        Dim oMsg As Outlook._MailItem
        oMsg = oApp.CreateItem(Outlook.OlItemType.olMailItem)
        oMsg.Subject = "Send Attachment Using OOM in Visual Basic .NET"
        oMsg.Body = "Hello World" & vbCr & vbCr

        ' TODO: Replace with a valid e-mail address.
        oMsg.To = "user@example.com"

        ' Add an attachment
        ' TODO: Replace with a valid attachment path.
        Dim sSource As String = "C:\Temp\Hello.txt"
        ' TODO: Replace with attachment name
        Dim sDisplayName As String = "Hello.txt"

        Dim sBodyLen As String = oMsg.Body.Length
        Dim oAttachs As Outlook.Attachments = oMsg.Attachments
        Dim oAttach As Outlook.Attachment
        oAttach = oAttachs.Add(sSource, , sBodyLen + 1, sDisplayName)

        ' Send
        oMsg.Send()

        ' Clean up
        oApp = Nothing
        oMsg = Nothing
        oAttach = Nothing
        oAttachs = Nothing
    End Sub

End Module

如何使所有Outlook项目（Outlook.Application，Outlook._MailItem，Outlook，Outlook.Attachments，Outlook.Attachment）获得未使用或未定义的引用。

提前致谢。

Answer 1

添加对“Microsoft Outlook 11.0对象库”的引用：

在“项目”菜单上，单击“添加引用”。
在“COM”选项卡上，单击“Microsoft Outlook 11.0对象库”，然后单击“选择”。
在“添加引用”对话框中单击“确定”以接受您的选择。如果系统提示您为所选库生成包装，请单击“是”。

在代码中你必须添加：

Imports Outlook = Microsoft.Office.Interop.Outlook

但是如果你在.NET中，为什么不使用System.Net.Mail？

Answer 2

在解决方案资源管理器中，右键单击项目并选择“添加引用”并向下滚动，直到看到Microsoft.Office.Interop.Outlook并选择该项。然后在VB文件的顶部添加“Imports Microsoft.Office.Interop”。

Imports Microsoft.Office.Interop

'On the Project menu, click Add Reference.
'On the COM tab, Double click ->  Microsoft Outlook xx.0 Object Library

Module Module1

    Sub Main()
        ' Create an Outlook application.
        Dim oApp As Outlook._Application
        oApp = New Outlook.Application()

        ' Create a new MailItem.
        Dim oMsg As Outlook._MailItem
        oMsg = CType(oApp.CreateItem(Outlook.OlItemType.olMailItem), Outlook._MailItem)
        oMsg.Subject = "Send Attachment Using OOM in Visual Basic .NET"
        oMsg.Body = "Hello World" & vbCr & vbCr

        ' TODO: Replace with a valid e-mail address.
        oMsg.To = "user@example.com"

        ' Add an attachment

        Dim sSource As String = "C:\Temp\Hello.txt"
        ' TODO: Replace with attachment name
        Dim sDisplayName As String = "Hello.txt"

        Dim sBodyLen As Integer = oMsg.Body.Length
        Dim oAttachs As Outlook.Attachments = oMsg.Attachments
        Dim oAttach As Outlook.Attachment
        oAttach = oAttachs.Add(sSource, , sBodyLen + 1, sDisplayName)

        ' Send
        oMsg.Send()

        ' Clean up
        oApp = Nothing
        oMsg = Nothing
        oAttach = Nothing
        oAttachs = Nothing
