如何使用mailkit在webview2中显示html电子邮件

问题描述

我目前正在使用 mailkit 和 visual basic 构建一个基本的电子邮件客户端。我已经能够在收件箱中获取电子邮件，但现在我希望能够在 Web 视图 2 中显示 HTML 电子邮件。mailkit 的所有文档都是用 C# 编写的，虽然我理解其中的大部分内容，但我不知道不知道如何正确地将其转换为可视化基本代码。这些是我一直在使用的链接： https://github.com/jstedfast/MailKit/blob/master/Documentation/Examples/ImapExamples.cs https://github.com/jstedfast/MailKit https://github.com/jstedfast/MimeKit/blob/master/samples/MessageReader/MessageReader/MessageViewWindow.cs

这是我写的：

Imports System
Imports MimeKit
Imports MailKit
Imports MailKit.Net.Imap
Imports MailKit.Security
Imports MailKit.Search
Imports System.Threading
Public Class ReceiveEmails
    Dim HasAttachment As Boolean = False
    Dim aryAttachments() As String
    Private Sub btnConnect_Click(sender As Object,e As EventArgs) Handles btnConnect.Click
        'Dim connectThread As New Thread(AddressOf Login)
        'connectThread.Start()
        BackgroundWorker1.RunWorkerAsync()

    End Sub
    Private Sub btnBack_Click(sender As Object,e As EventArgs) Handles btnBack.Click
        Me.Hide()
    End Sub
    Private Sub BackgroundWorker1_DoWork(sender As Object,e As ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
        'normally a thread or background worker cannot update the UI,but the line below is a cheap way to accomplish this task
        'not the ideal way to update the UI apparently,but it works
        CheckForIllegalCrossthreadCalls = False

        Dim username As String = txtAccount.Text.ToString
        Dim password As String = txtPassword.Text
        Dim imapServerName As String = cmbServer.SelectedItem

        Dim imapServer As New ImapClient(New ProtocolLogger("imap.log"))
        Dim i As Integer = 0

        imapServer.Connect(imapServerName,993,SecureSocketoptions.SslOnConnect)
        imapServer.Authenticate(username,password)
        imapServer.InBox.Open(FolderAccess.ReadOnly)

        Dim emailMessage = imapServer.InBox.GetMessage(i)

        For count As Integer = 0 To imapServer.InBox.Count - 1
            emailMessage = imapServer.InBox.GetMessage(count)
            'email subjects get listed in a list Box
            listemails.Items.Add(emailMessage.Subject)
        Next

        Dim query = SearchQuery.SubjectContains("")
        Dim uids = imapServer.InBox.Search(query)

        Dim items = imapServer.InBox.Fetch(uids,MessageSummaryItems.UniqueId)

    End Sub
End Class
