下面是将数据读入到dataset

public static DataSet CreateDataSource(string filePath)
        {
            try
            {
                string strConn;

                strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" +
                "Data Source=" + filePath + ";" +
                "Extended Properties=\"Excel 8.0;IMEX=1;\"";//连接

                OleDbConnection conn = new OleDbConnection(strConn);

                conn.Open();

                System.Data.DataTable schemaTable = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, null);

                string tableName = schemaTable.Rows[0][2].ToString().Trim();//得到excel表名

                OleDbDataAdapter myCommand = new OleDbDataAdapter("SELECT * FROM [" + tableName + "]", strConn);//查找excel数据

                DataSet myDataSet = new DataSet();//定义数据

                myCommand.Fill(myDataSet);

                conn.Close();

                return myDataSet;                
            }
            catch
            {
                throw;
            }
        }
