c#儲存生成excel表格格式xls、xlsx格式的檔案

需要電腦安裝對應版本的office，並且在專案中引用excel

測試程式碼

static void Main()
{
    List<string> alldata = new List<string>();
    alldata.Add("第一行");
    alldata.Add("第2行");
    alldata.Add("第叄行");
    list2excel(alldata,"列名","test.xls");
}

將list<string>

//匯出到execl，需要匯入Microsoft.Office.Interop.Excel
        public static void list2excel(List<String> strarray,string column_name,string path)
        {
            System.Data.DataTable dt = new System.Data.DataTable();
            dt.Columns.Add(column_name, System.Type.GetType("System.String"
 
));
            foreach ( String str in strarray)
            {
                DataRow dr = dt.NewRow();
                dr[0] = str;
                dt.Rows.Add(dr);
            }
            DataTabletoExcel(dt, path);

        }

將DataTable生成excel函式

public static bool DataTabletoExcel(System.Data
 
.DataTable dt, string AbosultedFilePath)
        {
            if (dt == null)
                return false;

            Microsoft.Office.Interop.Excel.Application excApp = new Microsoft.Office.Interop.Excel.Application();
            if (excApp==null)
            {
                MessageBox.Show("無法建立excel物件，可能您的電腦未安裝excel");
                return false;
            }
            Microsoft.Office.Interop.Excel.Workbook workBook = excApp.Workbooks.Add(Microsoft.Office.Interop.Excel.XlWBATemplate.xlWBATWorksheet);
            Microsoft.Office.Interop.Excel.Worksheet workSeet = workBook.Worksheets[1]; //取得sheet1
            Microsoft.Office.Interop.Excel.Range range = null;
            int tableCount = dt.Rows.Count;
            int rowRead = 0;
            float percent = 0;
            for (int i = 0; i < dt.Columns.Count; i++)
            {
                workSeet.Cells[1, i + 1] = dt.Columns[i].ColumnName;

                //設定標題的樣式
                range = (Microsoft.Office.Interop.Excel.Range)workSeet.Cells[1, i + 1];
                range.Font.Bold = true; //粗體
                range.Font.Size = "12";//字型大小
                range.Font.Name = "宋體";
                range.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter; //居中
                range.BorderAround(Microsoft.Office.Interop.Excel.XlLineStyle.xlContinuous, Microsoft.Office.Interop.Excel.XlBorderWeight.xlThin, Microsoft.Office.Interop.Excel.XlColorIndex.xlColorIndexAutomatic, null); //背景色
                range.EntireColumn.AutoFit(); //自動設定列寬
                range.EntireRow.AutoFit(); //自動設定行高
            }
            for (int r = 0; r < dt.Rows.Count; r++)
            {
                for (int c = 0; c < dt.Columns.Count; c++)
                {
                    //寫入內容
                    workSeet.Cells[r + 2, c + 1] = "'" + dt.Rows[r][c].ToString();
                    //設定樣式
                    range = (Microsoft.Office.Interop.Excel.Range)workSeet.Cells[r + 2, c + 1];
                    range.Font.Size = 9; //字型大小
                    range.BorderAround(Microsoft.Office.Interop.Excel.XlLineStyle.xlContinuous, Microsoft.Office.Interop.Excel.XlBorderWeight.xlThin, Microsoft.Office.Interop.Excel.XlColorIndex.xlColorIndexAutomatic, null); //加邊框
                    range.EntireColumn.AutoFit(); //自動調整列寬
                }
                rowRead++;
                percent = ((float)(100 * rowRead)) / tableCount;
                System.Windows.Forms.Application.DoEvents();
            }
            range.Borders[Microsoft.Office.Interop.Excel.XlBordersIndex.xlInsideHorizontal].Weight = Microsoft.Office.Interop.Excel.XlBorderWeight.xlThin;
            if (dt.Columns.Count > 1)
            {
                range.Borders[Microsoft.Office.Interop.Excel.XlBordersIndex.xlInsideVertical].Weight = Microsoft.Office.Interop.Excel.XlBorderWeight.xlThin;
            }
            try

                workBook.Saved = true;
