ASP.NET C#导出到excel时设置标题/标题的样式？

我正在尝试将我的asp.net excel导出样式设置得更好一些，但我不知道如何设置

我有以下代码

string filename = Constants.Fullname +"_CommissionSheet_"+DateTime.Now.ToString("MM/dd/yyyy")+".xls";

    Response.AddHeader("content-disposition", "attachment; filename="+filename);
    Response.Charset = "";
    // If you want the option to open the Excel file without saving than
    // comment out the line below
    // Response.Cache.SetCacheability(HttpCacheability.NoCache);

    Response.ContentType = "application/vnd.xls";
    System.IO.StringWriter stringWrite = new System.IO.StringWriter();
    System.Web.UI.HtmlTextWriter htmlWrite =
    new HtmlTextWriter(stringWrite);
    //Styling the gridView header for Excel.
    GridView1.HeaderRow.Style.Add("background-color", "#95c556");
    GridView2.HeaderRow.Style.Add("background-color", "#FF9900");
    GridView3.HeaderRow.Style.Add("background-color", "#db7464");

    int j = 1;
    //Set alternate row color
    foreach (GridViewRow gvrow in GridView1.Rows)
    {
        gvrow.BackColor = System.Drawing.Color.White;
        if (j <= GridView1.Rows.Count)
        {
            if (j % 2 != 0)
            {
                for (int k = 0; k < gvrow.Cells.Count; k++)
                {
                    gvrow.Cells[k].Style.Add("background-color", "#EFF3FB");
                }
            }
        }
        j++;
    }

    int jk= 1;
    //Set alternate row color
    foreach (GridViewRow gvrow in GridView2.Rows)
    {
        gvrow.BackColor = System.Drawing.Color.White;
        if (jk <= GridView2.Rows.Count)
        {
            if (jk % 2 != 0)
            {
                for (int k = 0; k < gvrow.Cells.Count; k++)
                {
                    gvrow.Cells[k].Style.Add("background-color", "#EFF3FB");
                }
            }
        }
        jk++;
    }

    int jkj = 1;
    //Set alternate row color
    foreach (GridViewRow gvrow in GridView3.Rows)
    {
        gvrow.BackColor = System.Drawing.Color.White;
        if (jkj <= GridView3.Rows.Count)
        {
            if (jkj % 2 != 0)
            {
                for (int k = 0; k < gvrow.Cells.Count; k++)
                {
                    gvrow.Cells[k].Style.Add("background-color", "#EFF3FB");
                }
            }
        }
        jk++;
    }

    //Add Header
    GridView1.Caption = "Paid:";
    GridView1.CaptionAlign = TableCaptionAlign.Left;

    GridView2.Caption = "Expected:";
    GridView2.CaptionAlign = TableCaptionAlign.Left;

    GridView3.Caption = "Unpaid:";
    GridView3.CaptionAlign = TableCaptionAlign.Left;


    GridView1.RenderControl(htmlWrite);
    GridView2.RenderControl(htmlWrite);
    GridView3.RenderControl(htmlWrite);
    Response.Write(stringWrite.ToString());
    Response.End();
    }

string filename=Constants.Fullname+“_CommissionSheet”+DateTime.Now.ToString（“MM/dd/yyyy”）+“.xls”；
Response.AddHeader（“内容处置”、“附件；文件名=“+filename”）；
响应。Charset=“”；
//如果希望在不保存的情况下打开Excel文件，则
//注释掉下面的行
//Response.Cache.SetCacheability（HttpCacheability.NoCache）；
Response.ContentType=“application/vnd.xls”；
System.IO.StringWriter stringWrite=新的System.IO.StringWriter（）；
System.Web.UI.HtmlTextWriter htmlWrite=
新的HtmlTextWriter（stringWrite）；
//为Excel设置gridView标题的样式。
GridView1.HeaderRow.Style.Add（“背景色”，“#95c556”）；
GridView2.HeaderRow.Style.Add（“背景色”，“FF9900”）；
GridView3.HeaderRow.Style.Add（“背景色”、“db7464”）；
int j=1；
//设置备用行颜色
foreach（GridViewRow gvrow在GridView1.Rows中）
{
gvrow.BackColor=System.Drawing.Color.White；
如果（j）你查过这个问题了吗？@Niklas，我没发现那个问题，我会查出来的。谢谢。
