javascript - 将图像从 SQL Server 插入到 Word 文档文件

Question

我想导出网页上显示的图像。该图像以 Sql 图像数据类型存储。显示图像时，我将图像转换为 Base64String。

Image1.ImageUrl = "data:image/jpg;base64," & Convert.ToBase64String(imgPhoto)    

导出页面时，图像未显示在Word文档文件中。

由于安全原因，我无法在服务器上存储图像。下面的代码用于导出到word文件。

    Response.AddHeader("content-disposition", "attachment;filename=Test.doc")
    Response.Cache.SetCacheability(HttpCacheability.NoCache)
    Response.ContentType = "application/ms-word "
    Response.Charset = ""
    Dim stringWrite As New System.IO.StringWriter()
    Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)

    ' Create a form to contain the grid
    ControlID.RenderControl(htmlWrite)

    Dim stringWrite1 As New System.IO.StringWriter()
    Dim htmlWrite1 As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite1)

    ' Create a form to contain the grid
    ImageLogo.RenderControl(htmlWrite1)

    Response.Write(stringWrite1.ToString() & stringWrite.ToString())
    Response.[End]()

您实际上并不是在创建 Word 文档，只是将 HTML 呈现为单词 MIME 类型。我不相信 word 支持 data:image 定义，因为它比 2007 年之前的 word 格式要新得多。相反，请尝试 OpenXML SDK。尽管它仅创建 Word 2007+ 文档，但大多数人都可以查看它们。 OpenXML SDK 将使您能够创建真实的文字文档并从二进制图像数据创建图像。
