圖形API SendMail帶附件，使用c＃中的REST示例＃

Question

Graph API Send Email文檔聲明我可以在同一個sendMail動作調用中包含文件附件。有人能夠提供一個示例代碼，說明如何使用me/sendmail和附件從生成內容存儲在內存流中的文件中實現這一點。

Answer 1

一種選擇是使用Microsoft Graph .NET SDK，我在另一個Stack Overflow answer中找到了此示例代碼。

// Create the message with attachment. 
byte[] contentBytes = System.IO.File.ReadAllBytes(@"C:\test\test.png"); 
string contentType = "image/png"; 
MessageAttachmentsCollectionPage attachments = new MessageAttachmentsCollectionPage(); 
attachments.Add(new FileAttachment 
{ 
    ODataType = "#microsoft.graph.fileAttachment", 
    ContentBytes = contentBytes, 
    ContentType = contentType, 
    ContentId = "testing", 
    Name = "testing.png" 
}); 
Message email = new Message 
{ 
    Body = new ItemBody 
    { 
     Content = Resource.Prop_Body + guid, 
     ContentType = BodyType.Text, 
    }, 
    Subject = Resource.Prop_Subject + guid.Substring(0, 8), 
    ToRecipients = recipients, 
    Attachments = attachments 
}; 

// Send the message. 
await graphClient.Me.SendMail(email, true).Request().PostAsync();
