C# 无法在ASP.NET中将数据导出为XML-将数据导出为HTML而不是XML

我想将ASP.NET web表单应用程序中的一些数据导出到可下载的XML文件中，但无法将下载的信息显示为XML文件。它将信息输出为html文档而不是XML

protected void ExportXMLButton_Click(object sender, EventArgs e)
{

    using (MemoryStream stream = new MemoryStream())
    {
        // Create an XML document. Write our specific values into the document.
        XmlTextWriter xmlWriter = new XmlTextWriter(stream, System.Text.Encoding.ASCII);
        // Write the XML document header.
        xmlWriter.WriteStartDocument();
        // Write our first XML header.
        xmlWriter.WriteStartElement("WebApplications");
        // Write an element representing a single web application object.
        xmlWriter.WriteStartElement("WebApplication");
        // Write child element data for our web application object.
        xmlWriter.WriteElementString("Date", DateTime.Now.ToString());
        xmlWriter.WriteElementString("Programmer", "Label1.Text");
        xmlWriter.WriteElementString("Name", "Sample name ");
        xmlWriter.WriteElementString("Language", "C# ");
        xmlWriter.WriteElementString("Status", "Done");
        // End the element WebApplication
        xmlWriter.WriteEndElement();
        // End the document WebApplications
        xmlWriter.WriteEndElement();
        // Finilize the XML document by writing any required closing tag.
        xmlWriter.WriteEndDocument();
        // To be safe, flush the document to the memory stream.
        xmlWriter.Flush();
        // Convert the memory stream to an array of bytes.
        byte[] byteArray = stream.ToArray();
        // Send the XML file to the web browser for download.
        Response.Clear();
        Response.AppendHeader("Content-Disposition", "filename=MyExportedFile.xml");
        Response.AppendHeader("Content-Length", byteArray.Length.ToString());
        Response.ContentType = "application/octet-stream";
        Response.BinaryWrite(byteArray);
        xmlWriter.Close();

    }
}

我希望输出是一个XML文件，但实际的输出是我的数据以文本形式显示在屏幕上。

您写入了错误的标题。使用：

Content-Disposition: attachment;filename=...
Content-Type: application/xml

至少。见：

我认为删除这一点就是答案：

Response.AppendHeader("Content-Length", byteArray.Length.ToString());

Xml是文本！！！！这可能取决于浏览器处理XML文档的方式。例如，在我的开发机器上，firefox设置为下载XML文件，Chrome设置为在浏览器中显示它们。谢谢。但是，它现在显示为html文档，而不是XML文档，这可能取决于您的浏览器配置。
