本文实例讲述了ASP.NET使用GridView导出Excel实现方法。分享给大家供大家参考。具体实现方法如下：

复制代码 代码如下:/// <summary>

/// 将DataTable数据导出到EXCEL，调用该方法后自动返回可下载的文件流

/// </summary>

/// <param name="dtData">要导出的数据源</param>

public static void DataTable1Excel(System.Data.DataTable dtData)

{

System.Web.UI.WebControls.GridView gvExport = null;

// 当前对话

System.Web.HttpContext curContext = System.Web.HttpContext.Current;

// IO用于导出并返回excel文件

System.IO.StringWriter strWriter = null;

System.Web.UI.HtmlTextWriter htmlWriter = null;

if (dtData != null)

{

// 设置编码和附件格式

curContext.Response.ContentType = "application/vnd.ms-excel";

curContext.Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");

curContext.Response.Charset = "utf-8";

// 导出excel文件

strWriter = new System.IO.StringWriter();

htmlWriter = new System.Web.UI.HtmlTextWriter(strWriter);

// 为了解决gvData中可能进行了分页的情况，需要重新定义一个无分页的GridView

gvExport = new System.Web.UI.WebControls.GridView();

gvExport.DataSource = dtData.DefaultView;

gvExport.AllowPaging = false;

gvExport.DataBind();

// 返回客户端

gvExport.RenderControl(htmlWriter);

curContext.Response.Write("<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />" + strWriter.ToString());

curContext.Response.End();

}

}

/// <summary>

/// 直接输出Excel

/// </summary>

/// <param name="dtData"></param>

public static void DataTable2Excel(System.Data.DataTable dtData)

{

System.Web.UI.WebControls.DataGrid dgExport = null;

// 当前对话

System.Web.HttpContext curContext = System.Web.HttpContext.Current;

// IO用于导出并返回excel文件

System.IO.StringWriter strWriter = null;

System.Web.UI.HtmlTextWriter htmlWriter = null;

if (dtData != null)

{

// 设置编码和附件格式

curContext.Response.ContentType = "application/vnd.ms-excel";

curContext.Response.ContentEncoding =System.Text.Encoding.UTF8;

curContext.Response.Charset = "";

// 导出excel文件

strWriter = new System.IO.StringWriter();

htmlWriter = new System.Web.UI.HtmlTextWriter(strWriter);

// 为了解决dgData中可能进行了分页的情况，需要重新定义一个无分页的DataGrid

dgExport = new System.Web.UI.WebControls.DataGrid();

dgExport.DataSource = dtData.DefaultView;

dgExport.AllowPaging = false;

dgExport.DataBind();

// 返回客户端

dgExport.RenderControl(htmlWriter);

curContext.Response.Write(strWriter.ToString());

curContext.Response.End();

}

}

希望本文所述对大家的asp.net程序设计有所帮助。
