public ArrayList ExcelSheetName(string filepath) { ArrayList al = new ArrayList(); string strConn; strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filepath + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1;\";"; OleDbConnection conn = new OleDbConnection(strConn); conn.Open(); DataTable sheetNames = conn.GetOleDbSchemaTable (System.Data.OleDb.OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" }); conn.Close(); foreach (DataRow dr in sheetNames.Rows) { al.Add(dr[2]); } return al; }這個方法獲取的EXCEL表名是按字母順序排列的，如果我要獲得EXCEL的第一個工作表名，怎么做？ 謝謝！
