如何使用asp.net和c＃stream式传输Excel 2007或Word 2007文件
我正在做一个networking应用程序，需要stream式传输各种文件。 我可以做PDF，图像和较旧的Office文档。 但是，当我试图用2007年的文件，它打破。 这是我的代码：
Response.Buffer = true; Response.Clear(); Response.ClearContent(); Response.ClearHeaders(); switch (FileExtension.ToLower()) { case "pdf": Response.ContentType = "application/pdf"; break; case "doc": Response.ContentType = "application/msword"; break; case "docx": Response.ContentType = "application/vnd.ms-word.document.12"; break; case "xls": Response.ContentType = "application/vnd.ms-excel"; break; case "xlsx": Response.ContentType = "application/vnd.ms-excel.12"; break; default: Response.ContentType = "image/jpeg"; break; } Response.BinaryWrite(buffer); 我得到的错误是：
在文本内容中find无效的字符。 处理资源'http：//DomainName/GetFile.aspx时出错... PK
有什么build议么？
根据简单的网页search，Word和Excel的正确的MIMEtypes是：
application/vnd.openxmlformats-officedocument.wordprocessingml.document application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

编辑：
以下简化示例适用于我。 它和你的不同之处在于它使用了一个通用的处理程序，而不是一个web表单（这对于类似的东西来说更适合）。
要testing它，请确保在应用程序的顶级文件夹中有一个名为Book1.xlsx的Excel 2007文件。
DownloadSpreadsheet.ashx: <%@ WebHandler Language="C#" Class="DownloadSpreadsheetHandler" %> using System; using System.Web; using System.IO; public class DownloadSpreadsheetHandler: IHttpHandler { public void ProcessRequest (HttpContext context) { context.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; string path = context.Server.MapPath("~/Book1.xlsx"); using (FileStream spreadsheet = File.OpenRead(path)) { CopyStream(spreadsheet, context.Response.OutputStream); } } public bool IsReusable { get { return false; } } private static void CopyStream(Stream input, Stream output) { byte[] buffer = new byte[32768]; while (true) { int read = input.Read(buffer, 0, buffer.Length); if (read <= 0) return; output.Write(buffer, 0, read); } } }

对于我们希望用Excel打开的csv格式文件，我们使用： Response.ContentType = "application/msexcel";
也许我们逃避这一点，因为它不是一个真正的xls文件，但是。
