Question

我有一个数据库字段varbinary，用于存储doc文档和pdf文件。

我想附上这样的流并通过电子邮件发送给我。电子邮件工作正常，没有附件。我尝试用文件测试（而不是从数据库中检索数据）但是我被'太多参数'公共子新（）'

所困扰

请帮忙。

Dim fileName As String = "C:\Users\tzvei\Documents\test.pdf"
        ' Get the file stream . 
        ' Requires the System.IO namespace.
        Dim fs As New FileStream(fileName, FileMode.Open, FileAccess.Read)
        Dim ms As New MemoryStream()
        ms.SetLength(fs.Length)
        fs.Read(ms.GetBuffer(), 0, CInt(fs.Length))

        m.Attachments.Add(New Attachment(ms, "test.pdf", "application/pdf")) 'here is the error Too many arguments

        ms.Flush()
        fs.Close()
        ms.Close()`

谢谢StuartLC 这工作

   Dim fileName As String = "C:\Users\tzvei\Documents\ReferenceLetter.pdf"
    ' Get the file stream for the error log. 
    ' Requires the System.IO namespace.
    Dim fs As New FileStream(fileName, FileMode.Open, FileAccess.Read)

    Dim mstream As New MemoryStream()
    mstream.SetLength(fs.Length)
    fs.Read(mstream.GetBuffer(), 0, CInt(fs.Length))
    Dim attach1 As New System.Net.Mail.Attachment(mstream, "blah", "application/pdf")

    m.Attachments.Add(attach1)

将内存流附加到电子邮件时的参数太多
