把EXCEL数据导入到C程序中
请问需要怎么样做，才能把EXCEL表中的数据导入到C#程序中的SQL SERVER数据库中 C# 数据库 Excel --------------------编程问答--------------------代码
protected void btnUpload_Click(object sender, EventArgs e)
{
DataSet ds = GetExcelData();
InsertDB(ds);
}
/// <summary>
/// 该方法实现从Excel中导出数据到DataSet中，其中filepath为Excel文件的绝对路径，sheetname为表示那个Excel表,此用Sheet1；
/// </summary>
/// <param name="ds">ds</param>
private void InsertDB(DataSet ds)
{
SqlConnection _con = new SqlConnection(@"Data Source=STKWX028\SQLEXPRESS;Initial Catalog=Library;Integrated Security=True");
SqlCommand cmd = new SqlCommand();
cmd.Connection = _con;
StringBuilder sb = new StringBuilder();
if (ds.Tables[0].Rows.Count > 0)
{
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
sb.Append(" INSERT INTO bookInfo(bookID,bookName,author,publisher,price,readerID,readerType,bookStatus) VALUES('");
sb.Append(ds.Tables[0].Rows[i].ItemArray[0].ToString() + "','");
sb.Append(ds.Tables[0].Rows[i].ItemArray[1].ToString() + "','");

sb.Append(ds.Tables[0].Rows[i].ItemArray[6].ToString() + "','");
sb.Append(ds.Tables[0].Rows[i].ItemArray[7].ToString() + "' ) ");
cmd.CommandText = sb.ToString();
}
}
_con.Open();
int j = cmd.ExecuteNonQuery();
_con.Close();
if (j > 0)
{
lblMessage.Text = "Insert into DB table Sucessfully!";
}
}

return ds;
}
复制一个。。。
补充：.NET技术 , ASP.NET
