Question

当我通过asp.net / C＃代码导出Excel文件时，它将保存为网页：它正在导出，但是当我打开相同的excel文件并尝试保存它时，它将保存为网页格式，我该如何更改？这些是我用于导出到excel的函数：

Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=Report1.xls");
Response.ContentType = "application/ms-excel";

const int BUFFER_SIZE = 16 * 1024;
int bytesRead = BUFFER_SIZE;
byte[] bytesBuffer = new byte[bytesRead];
///
memoryStream.Position = 0;
do
{
    bytesRead = memoryStream.Read(bytesBuffer, 0, bytesRead);
    Response.BinaryWrite(bytesBuffer);
    memoryStream.Flush();
} while (bytesRead > 0);
///

请尝试将您的aspx代码（请参阅下文）删除到您的网页中，并保留此信息：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Test.Default" %>

要删除的部分：

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>

    </div>
    </form>
</body>
</html>

...并在您的代码中：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Test
{
    public partial class Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Response.Clear();
            Response.AddHeader("content-disposition", "attachment;filename=Report1.xls");
            Response.ContentType = "application/ms-excel";

            const int BUFFER_SIZE = 16 * 1024;
            int bytesRead = BUFFER_SIZE;
            byte[] bytesBuffer = new byte[bytesRead];
            ///
            memoryStream.Position = 0;
            do
            {
                bytesRead = memoryStream.Read(bytesBuffer, 0, bytesRead);
                Response.BinaryWrite(bytesBuffer);
                memoryStream.Flush();
            } while (bytesRead > 0);
        }
    }
}

打开导出的excel文件并尝试保存它，保存为网页格式
