C# 导出到Excel并冻结顶行

作为一名编码员，我认为我的工作是制作工具和程序，使每个人的工作都更容易。我有一个ASP.NETGridView，它相当大，有20多页，对于会计人员来说，翻阅它非常麻烦。因此，我编写了一个导出到Excel按钮，它可以按预期工作。但现在，它们有一个很长的xls，很难记住哪列与哪种数据相关联。所以，我一直在寻找一种方法来导出启用了冻结窗格的相同xls，以便在第一行冻结时打开它。我没有找到一个这样做的例子

这是我目前所拥有的，它运行得很好，所以我不想改变方法。我只想让这个代码冻结第1行

protected void ExportGridviewToExcel(object sender, EventArgs e)
{
    string myMonth = MonthTextBox.Text;
    string myYear = YearTextBox.Text;
    SqlConnection myConn = new SqlConnection(ConfigurationManager.ConnectionStrings["InterfaceDev"].ConnectionString);
    string myCommandText = "GatherZeroBillingExtensions";
    SqlCommand myCommand = new SqlCommand(myCommandText, myConn);
    myCommand.CommandType = CommandType.StoredProcedure;
    myCommand.Parameters.AddWithValue("@Month", myMonth);
    myCommand.Parameters.AddWithValue("@Year", myYear);
    SqlDataAdapter myDataAdapter = new SqlDataAdapter(myCommand);
    DataSet myDataSet = new DataSet();
    myDataAdapter.Fill(myDataSet);
    DataTable myDataTable = myDataSet.Tables[0];
    ZeroBillExtGridView.AllowPaging = false;
    ZeroBillExtGridView.DataSource = myDataTable;
    ZeroBillExtGridView.DataBind();

    string myDesktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
    string myFilename = "ZeroBillingExtensions_" + DateTime.Now.ToShortDateString() + ".xls";
    string myFullyQualifiedPath = myDesktopPath + "\\" + myFilename;
    Response.ClearContent();
    Response.Buffer = true;
    Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", myFullyQualifiedPath));
    Response.ContentType = "application/ms-excel";
    StringWriter myStringWriter = new StringWriter();
    HtmlTextWriter myHtmlTextWriter = new HtmlTextWriter(myStringWriter);
    //Change the Header Row back to white color
    ZeroBillExtGridView.HeaderRow.Style.Add("background-color", "#FFFFFF");
    //Applying stlye to gridview header cells
    for (int i = 0; i < ZeroBillExtGridView.HeaderRow.Cells.Count; i++)
    {
        ZeroBillExtGridView.HeaderRow.Cells[i].Style.Add("background-color", "#507CD1");
    }
    int j = 1;
    //Set alternate row color
    foreach (GridViewRow gvrow in ZeroBillExtGridView.Rows)
    {
        gvrow.BackColor = System.Drawing.Color.White;
        if (j <= ZeroBillExtGridView.Rows.Count)
        {
            if (j % 2 != 0)
            {
                for (int k = 0; k < gvrow.Cells.Count; k++)
                {
                    gvrow.Cells[k].Style.Add("background-color", "#EFF3FB");
                }
            }
        }
        j++;
    }
    ZeroBillExtGridView.RenderControl(myHtmlTextWriter);
    Response.Write(myStringWriter.ToString());
    Response.End();
}

您不能使窗格冻结，因为您不是在实际创建Excel文档。您正在创建扩展名为.xls的HTML文档。HTML没有冻结窗格或行的概念。如果要使用Excel功能，需要使用OpenXML、XML、服务器上的Office Interop或第三方工具生成真正的Excel文档

请参见使用设置格式的示例

您正在将GridView导出为HTML。那是个坏主意。相反，使用一个库，例如，它专门支持冻结窗格。好吧，我们生活和学习。我不熟悉EPPlus，但只要在网站上停留几分钟，就可以清楚地看到它正是我所需要的。谢谢梅森！！梅森，我不得不再次发回邮件，感谢你把我引向EPPlus。多棒的工具库啊。我已经向一位开发人员朋友推荐了它。EPPlus是一个不错的选择！
