ASP.NET使用GridView導(dǎo)出Excel實(shí)現(xiàn)方法

    本文實(shí)例講述了ASP.NET使用GridView導(dǎo)出Excel實(shí)現(xiàn)方法。分享給大家供大家參考。具體實(shí)現(xiàn)方法如下：
    復(fù)制代碼 代碼如下:/// <summary>
    /// 將DataTable數(shù)據(jù)導(dǎo)出到EXCEL，調(diào)用該方法后自動(dòng)返回可下載的文件流
    /// </summary>
    /// <param name="dtData">要導(dǎo)出的數(shù)據(jù)源</param>
    public static void DataTable1Excel(System.Data.DataTable dtData)
    {
    System.Web.UI.WebControls.GridView gvExport = null;
    // 當(dāng)前對(duì)話
    System.Web.HttpContext curContext = System.Web.HttpContext.Current;
    // IO用于導(dǎo)出并返回excel文件
    System.IO.StringWriter strWriter = null;
    System.Web.UI.HtmlTextWriter htmlWriter = null;
    if (dtData != null)
    {
    // 設(shè)置編碼和附件格式
    curContext.Response.ContentType = "application/vnd.ms-excel";
    curContext.Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
    curContext.Response.Charset = "utf-8";
    // 導(dǎo)出excel文件
    strWriter = new System.IO.StringWriter();
    htmlWriter = new System.Web.UI.HtmlTextWriter(strWriter);
    // 為了解決gvData中可能進(jìn)行了分頁(yè)的情況，需要重新定義一個(gè)無(wú)分頁(yè)的GridView
    gvExport = new System.Web.UI.WebControls.GridView();
    gvExport.DataSource = dtData.DefaultView;
    gvExport.AllowPaging = false;
    gvExport.DataBind();
    // 返回客戶端
    gvExport.RenderControl(htmlWriter);
    curContext.Response.Write("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=gb2312\" />" + strWriter.ToString());
    curContext.Response.End();
    }
    }
    /// <summary>
    /// 直接輸出Excel
    /// </summary>
    /// <param name="dtData"></param>
    public static void DataTable2Excel(System.Data.DataTable dtData)
    {
    System.Web.UI.WebControls.DataGrid dgExport = null;
    // 當(dāng)前對(duì)話
    System.Web.HttpContext curContext = System.Web.HttpContext.Current;
    // IO用于導(dǎo)出并返回excel文件
    System.IO.StringWriter strWriter = null;
    System.Web.UI.HtmlTextWriter htmlWriter = null;
    if (dtData != null)
    {
    // 設(shè)置編碼和附件格式
    curContext.Response.ContentType = "application/vnd.ms-excel";
    curContext.Response.ContentEncoding =System.Text.Encoding.UTF8;
    curContext.Response.Charset = "";
    // 導(dǎo)出excel文件
    strWriter = new System.IO.StringWriter();
    htmlWriter = new System.Web.UI.HtmlTextWriter(strWriter);
    // 為了解決dgData中可能進(jìn)行了分頁(yè)的情況，需要重新定義一個(gè)無(wú)分頁(yè)的DataGrid
    dgExport = new System.Web.UI.WebControls.DataGrid();
    dgExport.DataSource = dtData.DefaultView;
    dgExport.AllowPaging = false;
    dgExport.DataBind();
    // 返回客戶端
    dgExport.RenderControl(htmlWriter);
    curContext.Response.Write(strWriter.ToString());
    curContext.Response.End();
    }
    }
    希望本文所述對(duì)大家的asp.net程序設(shè)計(jì)有所幫助。
