『壹』 求用winform导入导出excel的方法！！！另外我在调试时出错！！！
在这里补充一下，如果你的电脑安装了microso offices vs中的操作都好了还是出错的话，你看看你的offices办公软件安装在c盘，还是其他盘下。我当时遇到的问题是这样，我的是安装在d:盘了，结果换了c:盘就好了。
『贰』 求C#(winForm)将数据导出到Execl的实例 要cs文件全部代码
winForm中导出Execl的方法：
1、方法1：
SqlConnection conn=new SqlConnection(System.Configuration.ConfigurationSettings.AppSettings["conn"]);
SqlDataAdapter da=new SqlDataAdapter("select * from tb1",conn);
DataSet ds=new DataSet();
da.Fill(ds,"table1");
DataTable dt=ds.Tables["table1"];
string name=System.Configuration.ConfigurationSettings.AppSettings["downloarl"].ToString()+DateTime.Today.ToString("yyyyMMdd")+new Random(DateTime.Now.Millisecond).Next(10000).ToString()+".csv";//存放到 web.config中downloarl指定的路径，文件格式为当前日期+4位随机数
FileStream fs=new FileStream(name,FileMode.Create,FileAccess.Write);
StreamWriter sw=new StreamWriter(fs,System.Text.Encoding.GetEncoding("gb2312"));
sw.WriteLine("自动编号,姓名,年龄");
foreach(DataRow dr in dt.Rows)
{
sw.WriteLine(dr["ID"]+","+dr["vName"]+","+dr["iAge"]);
}
sw.Close();
Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(name));
Response.ContentType = "application/ms-excel";// 指定返回的是一个不能被客户端读取的流，必须被下载
Response.WriteFile(name); // 把文件流发送到客户端
Response.End();
public void Out2Excel(string sTableName,string url)
{
Excel.Application oExcel=new Excel.Application();
Workbooks oBooks;
Workbook oBook;
Sheets oSheets;
Worksheet oSheet;
Range oCells;
string sFile="",sTemplate="";
//
System.Data.DataTable dt=TableOut(sTableName).Tables[0];
sFile=url+"myExcel.xls";
sTemplate=url+"MyTemplate.xls";
//
oExcel.Visible=false;
oExcel.DisplayAlerts=false;
//定义一个新的工作簿
oBooks=oExcel.Workbooks;
oBooks.Open(sTemplate,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing, Type.Missing, Type.Missing);
oBook=oBooks.get_Item(1);
oSheets=oBook.Worksheets;
oSheet=(Worksheet)oSheets.get_Item(1);
//命名该sheet
oSheet.Name="Sheet1";
oCells=oSheet.Cells;
//调用mpdata过程，将数据导入到Excel中去
DumpData(dt,oCells);
//保存
oSheet.SaveAs(sFile,Excel.XlFileFormat.xlTemplate,Type.Missing,Type.Missing, Type.Missing, Type.Missing, Excel.XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing);
oBook.Close(false, Type.Missing,Type.Missing);
//退出Excel，并且释放调用的COM资源
oExcel.Quit();
GC.Collect();
KillProcess("Excel");
}
private void KillProcess(string processName)
{
System.Diagnostics.Process myproc= new System.Diagnostics.Process();
//得到所有打开的进程
try
{
foreach (Process thisproc in Process.GetProcessesByName(processName))
{
if(!thisproc.CloseMainWindow())
{
thisproc.Kill();
}
}
}
catch(Exception Exc)
{
throw new Exception("",Exc);
}
}
『叁』 C#winform 如何导出一定格式的excel啊
1.右击解决方案的引用，添加.NET中Microsoft.Office.Interop.Excel的引用；
2.在代码头添加using Microsoft.Office.Interop.Excel;
3.在函数中添加如下代码：
//创建
Microsoft.Office.Interop.Excel.Application excel1 = new Microsoft.Office.Interop.Excel.Application();
Workbook workbook1 = excel1.Workbooks.Add(true);
Worksheet worksheet1 = (Worksheet)workbook1.Worksheets["sheet1"];
//写入
worksheet1.Cells[1, 1] = "航班号";
worksheet1.Cells[1, 2] = "起飞地点";
worksheet1.Cells[1, 3] = "降落地点";
//显示
excel1.Visible = true;
Console.ReadLine();
//保存文件
workbook1.Close(true, "d:\\1.xls", null);
