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。
