{
public class ExcelOutput
{
public void ExcelTest()
{
//创建Excel应用程序
ApplicationClass excalApp = new ApplicationClass();
Workbook wb = excalApp.Workbooks.Add(Type.Missing);
Worksheet ws = (Worksheet)wb.ActiveSheet;
ws.Name = "第一个测试";
string item = "我是一个测试字";
ws.Cells[1, 1] = (object)item;
// 按格式保存工作簿
//XlFileFormat是一个枚举，提供很多存储格式，其中xlExcel8是Excel97-2003格式，xlExcel12是Excel2007格式
excalApp.ActiveWorkbook.SaveAs("f://test22", XlFileFormat.xlExcel8, Type.Missing, Type.Missing, Type.Missing, Type.Missing, XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
// 关闭Excel应用程序
