如何使用 c# 用 (-) 分隔的列標題拆分數據填充空行

Question

第一張照片是我當前在 excel 中的輸出，第二張照片顯示了我想要的

我遇到了問題，我在列標題名稱下方的數據集中插入一個空行，我希望用拆分的列標題名稱填充空行。 像（1-600,1-700,1-800 是分開的單元格，這里 1 是年，600 是周

這是我的代碼：

 private void button4_Click(object sender, System.EventArgs e)
    {
        GetDataSet();
    }
    private void GetDataSet()
    {
        try
        {
            SqlConnection conn = new SqlConnection(Connection);
            string data = null;
            //int i = 0;
            //int j = 0;

            Excel.Application xlApp;
            Excel.Workbook xlWorkBook;
            Excel.Worksheet xlWorkSheet;
            object misValue = System.Reflection.Missing.Value;

            xlApp = new Excel.Application();
            xlWorkBook = xlApp.Workbooks.Add(misValue);
            xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
            SqlCommand cmd = new SqlCommand("select * from [CAT].[Tables].[LT1005ReportYAS]", conn);
            cmd.Parameters.AddWithValue("@TransactionID", "2603_LT023_13022019174458");
            cmd.Parameters.AddWithValue("@StartDate", "2019-01-01");
            cmd.Parameters.AddWithValue("@EndDate", "2019-01-21");
            cmd.Parameters.AddWithValue("@ClientID", 1030);
            SqlDataAdapter da = new SqlDataAdapter();
            cmd.CommandType = CommandType.Text;
            cmd.CommandTimeout = 0;
            da.SelectCommand = cmd;
            DataSet ds = new DataSet();

            conn.Open();
            da.Fill(ds);
            var dr = ds.Tables[0].NewRow();
            ds.Tables[0].Rows.InsertAt(dr, 0);
            ds.Tables[0].TableName = "Retailer";
            ds.Tables[0].Columns.RemoveAt(0);
            ds.Tables[0].Columns.RemoveAt(0);


            Microsoft.Office.Interop.Excel.Application objexcelapp = new Microsoft.Office.Interop.Excel.Application();
            objexcelapp.Application.Workbooks.Add(Type.Missing);
            objexcelapp.Columns.AutoFit();
            for (int i = 1; i < ds.Tables[0].Columns.Count + 1; i++)
            {
                Microsoft.Office.Interop.Excel.Range xlRange = (Microsoft.Office.Interop.Excel.Range)objexcelapp.Cells[1, i];
                xlRange.Font.Bold = -1;
                xlRange.Borders.LineStyle = Microsoft.Office.Interop.Excel.XlLineStyle.xlContinuous;
                xlRange.Borders.Weight = 1d;

                objexcelapp.Cells[1, i] = ds.Tables[0].Columns[i - 1].ColumnName;
            }



            foreach (DataTable dt in ds.Tables)
            {
                for (int i1 = 0; i1 < dt.Columns.Count; i1++)
                {
                    xlWorkSheet.Cells[1, i1 + 1] = dt.Columns[i1].ColumnName;
                }
            }

            for (int i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
            {
                int s = i + 1;
                for (int j = 0; j <= ds.Tables[0].Columns.Count - 1; j++)
                {
                    data = ds.Tables[0].Rows[i].ItemArray[j].ToString();

                    xlWorkSheet.Cells[s + 1, j + 1] = data;
                    xlWorkSheet.Columns.AutoFit();
                    Microsoft.Office.Interop.Excel.Range xlRange = (Microsoft.Office.Interop.Excel.Range)xlWorkSheet.Cells[i + 2, j + 1];

        catch (Exception ex)

您可以使用 string.Split() 來完成您的要求。 例如：

string exampleValue = "1-600";

// This will split the string at the '-' (hyphen) character and produce an array with 2 values.
string[] splitString = exampleValue.Split('-');

Console.WriteLine(splitString[0]); // Expected output: 1.
Console.WriteLine(splitString[1]); // Expected output: 600.

這有幫助嗎？
