是否可以从 Razor/Blazor 组件中获取原始 HTML？

Question

我想使用 MailKit 设置“邮件/通讯”。 我的站点堆栈基于 Blazor web 组件和使用。Razor 组件。

I'm wondering if there is a way to consume a razor component I've written to output HTML into the MimeMessage object I'm using to generate my email body and what that architecture would look like / the best way to accomplish this?

类似的问题（虽然不是 Blazor）：

我在这里使用 Blazor 和 MailKit： Google Email Viewer in Server Side Blazor

我使用MarkupString来显示 email 内容，如下所示：

@using MimeKit
@using MessageReader
@strError
<div style="padding:2px; vertical-align:top">
    <div><i>@MimeKitMessage.Date.ToString()</i></div>
    <div><b>From:</b> @MimeKitMessage.From.ToString()</div>
    <div><b>To:</b> @MimeKitMessage.To.ToString()</div>
    <div><b>Subject:</b> @MimeKitMessage.Subject</div>
    <br />
    <div>@((MarkupString)@htmlEmail)</div>
</div>
@code {
    [Parameter] public Message paramMessage { get; set; }
    MimeMessage MimeKitMessage;
    string strError = "";
    string htmlEmail = "";
    protected override void OnInitialized()
    {
        try
        {
            if (paramMessage != null)
            {
                string converted = paramMessage.Raw.Replace('-', '+');
                converted = converted.Replace('_', '/');
                byte[] decodedByte = Convert.FromBase64String(converted);
                using (Stream stream = new MemoryStream(decodedByte))
                {
                    // Convert to MimeKit from GMail
                    // Load a MimeMessage from a stream
                    MimeKitMessage = MimeMessage.Load(stream);
                    // Convert any embedded images
                    var visitor = new HtmlPreviewVisitor();
                    MimeKitMessage.Accept(visitor);
                    htmlEmail = visitor.HtmlBody;
                    //If the email has attachments we can get them here
                    //var attachments = visitor.Attachments;
                }
            }
        }
        catch (Exception ex)
        {
            strError = ex.Message;
        }
    }    
}
