前些日子，有很多朋友说需要C#导出到Excel的代码，现共享给大家
///
/// 读取Excel文档
///
/// 文件名称
///
public DataSet ExcelToDS(string Path)
{
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" +"Data Source="+ Path +";"+"Extended Properties=Excel 8.0;";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
string strExcel = "";
OleDbDataAdapter myCommand = null;
DataSet ds = null;
strExcel="select * from [sheet1$]";
myCommand = new OleDbDataAdapter(strExcel, strConn);
ds = new DataSet();
myCommand.Fill(ds,"table1");
return ds;
}
///
/// 写入Excel文档
///
/// 文件名称
public bool SaveFP2toExcel(string Path)
{
try
{
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" +"Data Source="+ Path +";"+"Extended Properties=Excel 8.0;";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
System.Data.OleDb.OleDbCommand cmd=new OleDbCommand ();
cmd.Connection =conn;
//cmd.CommandText ="UPDATE [sheet1$] SET 姓名='2005-01-01' WHERE 工号='日期'";
//cmd.ExecuteNonQuery ();
for(int i=0;i
if(fp2.Sheets [0].Cells[i,0].Text!="")
{
cmd.CommandText ="INSERT INTO [sheet1$] (工号,姓名,部门,职务,日期,时间) VALUES('"+fp2.Sheets [0].Cells[i,0].Text+ "','"+
fp2.Sheets [0].Cells[i,1].Text+"','"+fp2.Sheets [0].Cells[i,2].Text+"','"+fp2.Sheets [0].Cells[i,3].Text+
"','"+fp2.Sheets [0].Cells[i,4].Text+"','"+fp2.Sheets [0].Cells[i,5].Text+"')";
cmd.ExecuteNonQuery ();
}
}
conn.Close ();
return true;
}
catch(System.Data.OleDb.OleDbException ex)
{
System.Diagnostics.Debug.WriteLine ("写入Excel发生错误："+ex.Message );
}
return false;
}
这种方法目前最有效，如果有不明白的地方可以来信交流
