NET导出Excel文件

.NET导出Excel文件

最近做ASP.NET Excel导出功能，顺便整理了一下可用的一些导出Excel方法 一般导出方式

1，客户提出要将统计的结果导出到excel文件，首先利用如下方式：

增加 <%@page contentType=\头部说明，然后放一个table在该页面中即可了。

2，客户看过后提出了改进意见，要求保存文件的时候自动给文件一个名称，这样可以直接保存。 改进如下：

增加 response.setHeader(\\但是却又遇到了乱码的问题：

response.setHeader(\

\将文件名称的编码由GBK转换为ISO-8859-1就正常了。 GridView导出Excel

尝试了一下Gridview导出为Excel，原本以为很简单，可是真正应用起来还是不太好弄的，呵呵，所想非所得。总结了一下应该注意下面几点：

1.由于gridview的内容可能是分页显示的，因此，这里在每次导出excel时，先将gridview的allowpaging属性设置为false，然后databind()一下，确保搂到所有数据； 2.不用单独设置导出的路径，导出时会弹出对话框让你确认保存位置；

3.要写一个空的VerifyRenderingInServerForm方法（必须写），以确认在运行时为指定的ASP.NET 服务器控件呈现HtmlForm 控件； 4.导出后别忘记再重新设置其allowpaging属性；

当我把这些都设置好以后，点击[导出]，出现了 只能在执行 Render() 的过程中调用 RegisterForEventValidation(RegisterForEventValidation can only be called during

Render(); ) 的错误，又检查代码，没发现问题啊，搞了一会弄不出来，然后搜索了一下，发现了解决办法：

修改你的aspx文件中的：

<%@ Page Language=\EnableEventValidation = \ AutoEventWireup=\CodeFile=\增加红色的部分就ok了。 下面是代码和截图： #region 导出为Excel

public override void VerifyRenderingInServerForm(Control control) {

// Confirms that an HtmlForm control is rendered for }

private void ToExcel(Control ctl, string FileName) {

HttpContext.Current.Response.Charset = \

HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8; HttpContext.Current.Response.ContentType = \ HttpContext.Current.Response.AppendHeader(\\ ctl.Page.EnableViewState = false;

System.IO.StringWriter tw = new System.IO.StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(tw); ctl.RenderControl(hw);

HttpContext.Current.Response.Write(tw.ToString()); HttpContext.Current.Response.End(); }

private void toExcelClk() {

gvSysUser.AllowPaging = false; gvSysUser.AllowSorting = false; gvSysUser.DataBind();

ToExcel(gvSysUser, \ gvSysUser.AllowPaging = true; gvSysUser.AllowSorting = true; gvSysUser.DataBind(); }

ASP.NET导出Excel、World文档

对于大量的数据，有时候导出到Excel中将更加方便进行数据统计分析，而对于排版打印则导出到World文档中更加方便。在ASP.NET可以通过少量代码实现这两种导出。 新建一页面，该页面布局Html源码如下：

这里没有什么特别的，只需要注意在线打开与本地保存两个按钮通过CommandName进行检验并触发相应的动作，DropDownList控件存放了可以导出的格式，可以自己添加如txt、html等格式。准备工作就绪以后，可以进行代码的书写，以完成我们需要的功能： protected void Page_Load(object sender, EventArgs e) {

FillGridView(); }

private void OutPut(string fileType, string strType) {

Response.Clear();

Response.Buffer = true;

Response.Charset = \

Response.AppendHeader(\ Response.ContentType = strType; this.EnableViewState = false;

System.IO.StringWriter swOut = new System.IO.StringWriter(); HtmlTextWriter hTw = new HtmlTextWriter(swOut);

myGW.RenderControl(hTw);

Response.Write(swOut.ToString()); Response.End(); }

protected void Button_Click(object sender, CommandEventArgs e) {

switch (e.CommandName) {

case \

switch (listType.SelectedValue) {

case \

OutPut(\; break; case \

OutPut(\ break; }

break; case \

switch (listType.SelectedValue) {

case \

OutPut(\ break; case \

OutPut(\ break; }

break; } }

public override void VerifyRenderingInServerForm(Control control) { }

private void FillGridView() {

string strConn = \id=sa;password=sa123\

SqlConnection conn = new SqlConnection(strConn); SqlCommand comm = new SqlCommand(); comm.Connection = conn;

string strSql = \ comm.CommandText = strSql;

conn.Open();

this.myGW.DataSource = comm.ExecuteReader(); this.myGW.DataBind(); conn.Close(); }

在以上的程序中，最主要的就是函数OutPut(string fileType, string strType)，它完成导出或在线打开的动作，这里接受两个参数其中fileType指定是保存或在线打开，并且指名了文件的名字如：attachment;filename=out.xls（作为附件保存，文件名为out.xls）、online;filename=out.xls（在线打开）；strType指定了带出文档的格式如application/ms-excel。

注意如果想要导出GridView中的数据并且要我们的程序顺利执行，则必须重写VerifyRenderingInServerForm(Control control)，否则会报错的。

如果我们想要将整个页面导出到Excel中，则不需要重写

VerifyRenderingInServerForm，只需要将OutPut函数中的myGW.RenderControl(hTw)改为this.RenderControl(hTw)就可以了。

完成以上工作，在浏览器中测试，我们想要的导出功能就可以很好的工作了。 利用Office中导出的Excel.dll（DCOM方式）

这个类可以很好的控制Excel。读出内容想怎么导就怎么导 ///
