這些圖像是在運行時決定的，無論如何將它嵌入到 email 主體中

請幫忙

Answer 1

如果您只想要 email 中的那部分標記，則將其放在用戶控件 (myEmailControl.ascx) 中。 然后，您可以從發送 email 的腳本調用控件上的 Render() 並攔截控件的 html output。 然后你可以將 html 放入 email 主體中。 （您的圖片還需要絕對網址，以便它們顯示在 email 中，但我相信您已經想到了）

發送 email 的頁面/處理程序：

    StringBuilder htmlResponse = new StringBuilder();
    using (StringWriter sw = new StringWriter(htmlResponse))
    {
        using (HtmlTextWriter textWriter = new HtmlTextWriter(sw))
        {
            Control emailBody = Page.LoadControl("myEmailControl.ascx");
            emailBody.RenderControl(textWriter);
        }
    }
    string emailHtml = htmlResponse.ToString();

Answer 2

您可以從頁面下載呈現的 HTML 並發送：

WebRequest request = WebRequest.Create("http://server.com/path/to/page.aspx");
WebResponse response = request.GetResponse();

StringReader reader = new StringReader(response.GetResponseStream());

string html = reader.ReadToEnd();

現在你可以在你的html中發送 html 的內容。

Answer 3

您最好的選擇可能是將 output 圖像作為 HTML 中的 Base 64。

<img src="data:image/png;base64,iVBrkJggg==" alt="Base 64 encoded!" /> 

在后面的代碼中，獲取圖像，將其轉換為 Base 64 並將其打印為 src！
