顶起来 --------------------编程问答-------------------- 看例子，从excel表里获取数据到dataset中
--------------------编程问答--------------------
private System.Data.DataTable GetExcelTable(string uploadPath)
{
DataSet ds = new DataSet();
string Xls_ConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + uploadPath + ";Extended Properties='Excel 8.0;HDR=YES;IMEX=1';";//HDR为yes 则第一数据行为列名,为no 则自动为列加列名F1 F2 F3
OleDbConnection Conn = new OleDbConnection(Xls_ConnStr);
try
{
Conn.Open();
string sql_str = "select * from [Sheet1$]";
OleDbDataAdapter da = new OleDbDataAdapter(sql_str, Conn);
da.Fill(ds, "excel_data");
Conn.Close();
}
catch
{
if (Conn.State == ConnectionState.Open)
{
Conn.Close();

return null;

finally

Conn.Dispose();

{
return null;
