Asp.net中把Excel資料存放區至SQL Server中的具體實現方法

ExcelWrapper

複製代碼 代碼如下: /// <summary>
/// 查詢EXCEL試算表添加到DATASET
/// </summary>
/// <param name="filenameurl">檔案路徑</param>
/// <param name="table">dataset中的表名(並不是要和資料庫中的表一樣)</param>
/// <returns></returns>
public static DataSet ExecleDs(string filenameurl, string table)
{
string strConn = "Provider=Microsoft.Jet.OleDb.4.0;"

+ "data source=" + filenameurl + ";Extended Properties='Excel 8.0; HDR=YES; IMEX=1'";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
DataSet ds = new DataSet();
OleDbDataAdapter odda = new OleDbDataAdapter("select * from [Sheet1$]", conn);
odda.Fill(ds, table);
return ds;
}
