C# WinForm程序中將DataGridView中的數據導出爲EXCEL

這是一種最簡單的一種導表的方法。

步驟如下：

1、添加 Microsoft.Office.Interop.Excel的引用。

2、添加下面的方法到你的類中：

        /// <summary>
        /// 將DataGridView控件中數據導出到Excel
        /// </summary>
        /// <param name="gridView">DataGridView對象</param>
        /// <param name="isShowExcele">是否顯示Excel界面</param>
        /// <returns></returns>
        public bool ExportDataGridView(DataGridView gridView, bool isShowExcele)
        {
            if (gridView.Rows.Count == 0)
                return false;
            //創建Excel對象
            Excel.Application excel = new Excel.Application();
            excel.Application.Workbooks.Add(true);
            excel.Visible = isShowExcele;
            //生成字段的名稱
            for (int i = 0; i < gridView.ColumnCount; i++)
            {
                excel.Cells[1, i + 1] = gridView.Columns[i].HeaderText;
            }
            //填充數據
            for (int i = 0; i < gridView.RowCount; i++)
            {
                for (int j = 0; j < gridView.ColumnCount; j++)
                {
                    if (gridView[j, i].ValueType == typeof(string))
                    {
                        excel.Cells[i + 2, j + 1] = gridView[j, i].Value.ToString();
                    }
                    else
                    {
                        excel.Cells[i + 2, j + 1] = gridView[j, i].Value.ToString();
                    }
                }
            }
            return true;
        }

3、調用的方法的寫法：

        private void 導出數據ToolStripMenuItem1_Click(object sender, EventArgs e)
        {
            if (!ExportDataGridView(dataGridView_CarsInfo, true))
            {
                MessageBox.Show("表格中沒有數據，無法導出數據！", "系統提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
        }
