Question

我正在创建一份日常报告的excel工作簿。我希望标题部分变为黄色。发布的所有链接都需要要打开的工作簿链接或不是特定于probelm的链接。我在这里发布我的代码，请建议如何使第6行为黄色。

    string workBookName;

        // creating Excel Application
        Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();


        // creating new WorkBook within Excel application
        Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);


        // creating new Excelsheet in workbook
        Microsoft.Office.Interop.Excel._Worksheet worksheet = null;

        // see the excel sheet behind the program
        app.Visible = true;

        // get the reference of first sheet. By default its name is Sheet1.
        // store its reference to worksheet
        worksheet = workbook.Sheets["Sheet1"];
        worksheet = workbook.ActiveSheet;

        // changing the name of active sheet
        workBookName = DateTime.Now.ToString("ddMMMyyyy-HHmmss");
        worksheet.Name = workBookName;

        worksheet.Cells[1, 1] = "Logistics";
        worksheet.Cells[2, 1] = "Tracking Number";

        worksheet.Cells[4, 2] = "Date - ";
        worksheet.Cells[4, 3] = dateTimePicker1.Value.ToString("dd/MMM/yyyy");


        // storing header part in Excel
        for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
        {
            worksheet.Cells[6, i] = dataGridView1.Columns[i - 1].HeaderText;
           // worksheet.get_Range(worksheet.Cells[6, i]).Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Green);
        }



        // storing Each row and column value to excel sheet
        for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
        {
            for (int j = 0; j < dataGridView1.Columns.Count; j++)
            {
                //if (!string.IsNullOrWhiteSpace(dataGridView1.Rows[i].Cells[j].Value))
                {
                    worksheet.Cells[i + 8, j + 1] = dataGridView1.Rows[i].Cells[j].Value;


                }
            }
        }


        // save the application
        workbook.SaveAs("Tracking Number Report " + workBookName + ".xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

        // Exit from the application
        app.Quit();

我想要第6行，在我的情况下，标题部分是彩色的。

如果您运行此代码，最终仍会运行Excel实例，因为您尚未使用.ReleaseComObject调用在互操作中释放资源 - 有关此here的更多信息

我更喜欢使用其中一个Open XML库，例如EPPlus来处理这类事情。它使事情变得更简单，并且可以很容易地为一行着色。

尝试这样的事情：

using (var excel = new ExcelPackage())
{
    var workBookName = DateTime.Now.ToString("ddMMMyyyy-HHmmss");
    var worksheet = excel.Workbook.Worksheets.Add(workBookName);


    worksheet.Cells[1, 1].Value = "Logistics";
    worksheet.Cells[2, 1].Value = "Tracking Number";

    worksheet.Cells[4, 2].Value = "Date - ";
    worksheet.Cells[4, 3].Value = dateTimePicker1.Value.ToString("dd/MMM/yyyy");

    for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
    {
        worksheet.Cells[6, i].Value = dataGridView1.Columns[i - 1].HeaderText;
    }
    worksheet.Cells["6:6"].Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
    worksheet.Cells["6:6"].Style.Fill.BackgroundColor.SetColor(Color.Yellow);
    //
    //..etc
    //
    excel.SaveAs(new FileInfo("Tracking Number Report " + workBookName + ".xlsx"));
}

在Excel中为特定行着色C＃
