c# winform如何将数据存到指定excel表,并实时显示

Answer 1

补充和小技巧：
using Excel = Microsoft.Office.Interop.Excel; // 简化命名空间

在窗体事件中执行：
var xlsApp = new Excel.Application();
var wb = xlsApp.Workbooks.Add();
var sh = wb.ActiveSheet as Excel.Worksheet;
sh.Range["A1"].Value = "C# -> Excel 示例";

for (int row = 2; row <= 10; row++)
{
for (int col = 1; col <= 10; col++)
{
sh.Cells[RowIndex: row, ColumnIndex: col].Value = string.Format("{0}, {1}", row, col);
}
}
// 保存文件到 C 盘，请根据自己的 Excel 版本确定 FileFormat
// sh.SaveAs(Filename: "C:\\test.xls", FileFormat: Excel.XlFileFormat.xlExcel12);
xlsApp.Visible = true;
// xlsApp.Quit();
