ASP.NET使用GridView導出Excel實現方法

    本文實例講述了ASP.NET使用GridView導出Excel實現方法。分享給大家供大家參考。具體實現方法如下：
    復制代碼 代碼如下:/// <summary>
    /// 將DataTable數據導出到EXCEL，調用該方法后自動返回可下載的文件流
    /// </summary>
    /// <param name="dtData">要導出的數據源</param>
    public static void DataTable1Excel(System.Data.DataTable dtData)
    {
    System.Web.UI.WebControls.GridView gvExport = null;
    // 當前對話
    System.Web.HttpContext curContext = System.Web.HttpContext.Current;
    // IO用于導出并返回excel文件
    System.IO.StringWriter strWriter = null;
    System.Web.UI.HtmlTextWriter htmlWriter = null;
    if (dtData != null)
    {
    // 設置編碼和附件格式
    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中可能進行了分頁的情況，需要重新定義一個無分頁的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;
    // 當前對話
    System.Web.HttpContext curContext = System.Web.HttpContext.Current;
    // IO用于導出并返回excel文件
    System.IO.StringWriter strWriter = null;
    System.Web.UI.HtmlTextWriter htmlWriter = null;
    if (dtData != null)
    {
    // 設置編碼和附件格式
    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中可能進行了分頁的情況，需要重新定義一個無分頁的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();
    }
    }
    希望本文所述對大家的asp.net程序設計有所幫助。
