Question

我有几次测试运行三次，平均值是通过c＃代码计算出来的。我可以写三次测试时间，如果按照下面的图片格式 xls file format 创建，则平均到xls文件。但现在我必须每天通过使用Windows调度程序的批处理文件每小时运行一次测试。我想以下面提到的格式动态创建xls文件，并使用特定的名称，以便在第一次迭代时创建文件，然后在接下来的19次迭代中，它应该在同一个文件中写入，然后在下一个小时使用特定文件创建新文件name.How如何动态创建和编写excel文件????? 如果有任何其他简单的程序PLZ建议。我用来编写已经创建的xls文件的代码是：`/ *

using System;
using System.IO;
using Ranorex;

namespace PEPI_Performance.Utility
{
/// <summary>
/// Description of ExcelWriter.

public class ExcelWriter
{
    /// <summary>
    /// Constructs a new instance.
    /// </summary>
    public ExcelWriter()
    {
        // Do not delete - a parameterless constructor is required!

        fnOpenExcel(sFilePath,sheetName);
        writeExcel(row,col,time);

有一种方法可以使用数据网格来处理这个问题。

下面的示例接受一个DataSet（您可以传递一个列表或表）。

然后在FLY上创建GridView并导出到Excel。我在很多网站上使用这种方法。

public static void ExportDataSetToExcel(DataSet ds, string filename)
{
    try
    {
        HttpResponse response = HttpContext.Current.Response;

        // first let's clean up the response.object
        response.Clear();
        response.Charset = "";

        // set the response mime type for excel
        response.ContentType = "application/vnd.ms-excel";
        response.AddHeader("Content-Disposition", "attachment;filename=\"" + filename + "\"");

        // create a string writer
        using (StringWriter sw = new StringWriter())
        {
            using (HtmlTextWriter htw = new HtmlTextWriter(sw))
            {
                // instantiate a datagrid
                DataGrid dg = new DataGrid();
                dg.DataSource = ds;
                dg.DataBind();
                dg.RenderControl(htw);
                response.Write(sw.ToString());
                response.End();
            }
        }
    }
    catch { }
}

说实话，你可能最好使用csv文件，从你的ranorex测试中你可以简单地使用system.IO.File将输出文本写入文件，而csv格式的优点是它然后可以在excel中打开
