C#连接Oracle数据库的方法

1.引用Oracle.ManagedDataAccess，利用Nuget查找Oracle.ManagedDataAccess

2.在config中加入连接oracle数据库的字符串

3.cs

添加引用

using Oracle.ManagedDataAccess;
using Oracle.ManagedDataAccess.Types;
using Oracle.ManagedDataAccess.Client;

 1 public DataTable GetSPstoDataTable(string proNo, string proDsc)

 7             OperationResult returnResult = new OperationResult();
 8             List<OracleParameter> lsPar = new List<OracleParameter>();
 9             string sql = "";

4.调用

 1 public JsonResult GetJDEspinfo(int limit, int offset, string SPItemNo, string Desc)
 2         { 
 3             BaseManager bm = new BaseManager();
 4             var data1 = bm.GetSPstoDataTable(SPItemNo, Desc); 
 5             int total = data1.Rows.Count;
 6             var List = data1.AsEnumerable().Select(p => new
 7             {
 8                 Building = p.Field<string>("BUILDING"),
 9                 Spname1 = p.Field<string>("SPNAME1"),
10                 SPItemNo = p.Field<string>("SPITEMNO"),
11                 Loction = p.Field<string>("LOCATION"),
12                 Qty = p.Field<Decimal>("QTY"), 
13             });//.OrderBy(a => a.SPItemNo); //.Skip(pageSize * (pageIndex - 1)).Take(pageSize);
14             var datalist = from a in List.ToList() select new { Building = a.Building, Spname1 = a.Spname1, SPItemNo = a.SPItemNo, Loction = a.Loction, Qty = a.Qty }; 
15             //var datalist = from a in List.ToList() select new { SPItemNo = a.SPItemNo };
16             var result = new { total = total, rows = datalist.Skip(50) };
17             return Json(datalist, JsonRequestBehavior.AllowGet);
