如何使用Interop C＃隱藏Excel列和行

Question

我創建了一個簡單的庫存界面，它將從我的界面上的數據網格視圖中訪問和顯示數據，然后通過按鈕點擊將信息發送到Excel。 此部分根據需要工作，但我想在發送信息后刪除未使用的列和行。 我目前正在使用VS 2015.我無法弄清楚要添加什么來實現這一目標。

//send to excel
    private void btnExport_Click(object sender, EventArgs e)
    {
        ActiveControl = txtSerial;
        // 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
        worksheet.Name = "Inventory Search";

        // storing header part in Excel
        for (int i = 1; i < dataGridFB.Columns.Count + 1; i++)
        {
            worksheet.Cells[1, i] = dataGridFB.Columns[i - 1].HeaderText;
            worksheet.Cells[1, i].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.LightBlue);
            worksheet.Cells[1, i].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Black);
            worksheet.Cells[1, i].HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;
            worksheet.Cells[1, i].Font.Size = 14;
        }

        // storing Each row and column value to excel sheet
        for (int i = 0; i < dataGridFB.Rows.Count - 1; i++)
        {
            for (int j = 0; j < dataGridFB.Columns.Count; j++)
            {
                worksheet.Cells[i + 2, j + 1] = dataGridFB.Rows[i].Cells[j].Value.ToString();
                worksheet.Cells[i + 2, j + 1].HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;
                worksheet.Cells[i + 2, j + 1].Font.Size = 12;
                worksheet.Columns["A:G"].AutoFit();
            }
        }
    }

Answer 1

您的問題有點過於寬泛，因此答案是通用的：為了刪除整個工作表列，您可以使用VBA語句，如： Columns("C").Delete, or Columns(3).EntireColumn.Delete或Columns("F:K").Delete 。 類似的語法可能適用於： Rows(3).Delete 。

為了隱藏行/列，請使用如下所示的VBA語句：

Rows("3:10").EntireRow.Hidden = True
Columns("C").Hidden = True

希望這可能有所幫助。
