C#用oledb读取Excel数据

string strConn = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source= " + v_strExcelPath + ";Extended Properties='Excel 12.0;IMEX=1'";

            OleDbDataAdapter myDataAdapter = null;
            OleDbConnection conn = new OleDbConnection(strConn);
            OleDbCommand myOleDbCommand = new OleDbCommand("SELECT * FROM [" + v_strSheetName + "$]", conn);

            try
            {
                conn.Open();
                myDataAdapter = new OleDbDataAdapter(myOleDbCommand);
                myDataAdapter.Fill(dt);
                conn.Dispose();
            }

读取Excel中的所有栏位名称：

ArrayList lv_arrList = new ArrayList();
            string strConn = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source= " + v_strExcelPath + ";Extended Properties='Excel 12.0;IMEX=1'";
            OleDbConnection conn = new OleDbConnection(strConn);
            try
            {               
                conn.Open();
                DataTable sheetname = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });
                conn.Close();
                conn.Dispose();
                foreach (DataRow dr in sheetname.Rows)
                {
                    lv_arrList.Add(dr[2].ToString().Replace("$", "").Replace("'", ""));
                }
            }
