最近在做一个打印清单的，但是rdlc报表自带的工具栏中的打印按钮只有在ie内核下的浏览器才可以使用（其他的就会隐藏），这导致了使用火狐和谷歌浏览器还有使用linux系统的客户打印成了问题，于是就自己百度搜，谷歌搜，然后就解决了，下面放上源码

打印类 PrintHelp（我需要两个table座位数据源所以参数中有两个datatable）

调用很简单直接一句话

new PrintHelp().Run(AppDomain.CurrentDomain.BaseDirectory + "\\Reports\\Report.rdlc", this.TextBox1.Text.Trim(), stationapplication.dthead, "headsource", stationapplication.dtmessage, "datasource", true);

由于原来的工具栏没了打印按钮所以也就没有存在的必要了隐藏掉自己做一个工具栏出来

///     /// 刷新    /// 
    ///     ///     protected void Button7_Click(object sender, EventArgs e)    {        this.ReportViewer1.LocalReport.Refresh();    }    ///     /// 首页    ///

导出文件

protected void Button3_Click(object sender, EventArgs e)    {        ExportFile(FileType.PDF, "out.pdf");    }    protected void Button4_Click(object sender, EventArgs e)    {        ExportFile(FileType.Image, "out.jpeg");//这里可以使用任意的图片格式  只要修改out.jpeg为其他格式的名字就可以了    }    protected void Button5_Click(object sender, EventArgs e)    {        ExportFile(FileType.Excel, "out.xls");    }    protected void Button6_Click(object sender, EventArgs e)    {        ExportFile(FileType.Word, "out.doc");    }    #region 導出文件    private void ExportFile(FileType ft, string filename)    {        CreateFile(ft, filename);        string strPath = Server.MapPath(filename);        DownloadFile(strPath, filename);    }    private void CreateFile(FileType ft, string filename)    {        Warning[] warnings;        string[] streamids;        string mimeType;        string encoding = "utf-8";        string extension;        byte[] bytes = this.ReportViewer1.LocalReport.Render(ft.ToString(), null, out mimeType,                       out encoding, out extension, out streamids, out warnings);        FileStream fs = new FileStream(HttpContext.Current.Server.MapPath(filename), FileMode.Create);        fs.Write(bytes, 0, bytes.Length);        fs.Close();        fs.Dispose();    }    public void DownloadFile(string path, string name)    {        try        {            System.IO.FileInfo file = new System.IO.FileInfo(path);            Response.Clear();            Response.Charset = "utf-8";            Response.ContentEncoding = System.Text.Encoding.UTF8;            // 添加头信息，为"文件下载/另存为"对话框指定默认文件名            Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(name));            // 添加头信息，指定文件大小，让浏览器能够显示下载进度            Response.AddHeader("Content-Length", file.Length.ToString());            // 指定返回的是一个不能被客户端读取的流，必须被下载            Response.ContentType = "application/octet-stream";            // 把文件流发送到客户端            Response.WriteFile(file.FullName);            // 停止页面的执行             HttpContext.Current.ApplicationInstance.CompleteRequest();        }        catch (Exception ex)        {            Response.Write("");        }    }
