C# ASP。Net Web API服务连接到oracle数据库

我是AP.NETMVC服务的新手，正在尝试创建一个web服务，在该服务中，我们将提供连接到oracle数据库的输入数组，并返回查询（过滤器中使用的输入需求数组）结果。我尝试不使用实体数据模型，并在模型类中提供POCO类。因此，我尝试创建一个简单的控制器，从数据库中选择整个数据

 public class TestOraConnController : ApiController
 {
     public string Get(int id)
     {
        var strQuery = @"Select PRIO_CATEGORY_ID as PRIO,LANG_ID as LANG, REC_DATE as REC, REC_USER as RECUSER, RFCH_ID as RFCH,DESCR,COL_DESCR AS COL,ROW_DESCR as DROW,ABBR from STCD_PRIO_CATEGORY_DESCR where REC_USER =" +id;
        OracleConnection dbConn = new OracleConnection("DATA SOURCE=ABC;PASSWORD=ABCD;PERSIST SECURITY INFO=True;USER ID=ABC");
        dbConn.Open();
        OracleCommand selectCommand = new OracleCommand(strQuery, dbConn);
        OracleDataAdapter adapter = new OracleDataAdapter(selectCommand);
        DataTable selectResults = new DataTable();
        adapter.Fill(selectResults);
        dbConn.Close();

        return JsonConvert.SerializeObject(selectResults);
}

所以结果看起来

 "[{\"PRIO\":1,\"LANG\":1,\"REC\":\"2011-10-23T20:32:18\",\"RECUSER\":1,\"RFCH\":null,\"DESCR\":\"Internal Study\",\"COL\":\"Internal    Study\",\"DROW\":\"Internal Study\",\"ABBR\":\"Intern\"},{\"PRIO\":1,\"LANG\":2,\"REC\":\"2011-10-23T20:32:18\",\"RECUSER\":1,\"RFCH\":null,\"DESCR\":\"Internal Study\",\"COL\":\"Internal Study\",\"DROW\":\"Internal Study\",\"ABBR\":\"Intern\"},{\"PRIO\":2,\"LANG\":1,\"REC\":\"2011-10-23T20:32:31\",\"RECUSER\":1,\"RFCH\":null,\"DESCR\":\"Client Study\",\"COL\":\"Client Study\",\"DROW\":\"Client Study\",\"ABBR\":\"Client\"}]"

现在，如果我需要给出输入参数的数组，我就是如何通过参数数组进行交互选择。我知道我们给了

 public string get( int []d) 

但不确定我们需要如何更改查询。非常感谢任何hep。

如果保留“strQuery”变量，可以使用IN关键字：

SELECT * FROM TABLE WHERE ID IN (id1, id2, ..., idn)

和方法来格式化您的ID

var ints = new int[] {1, 2, 3, 4, 5};
var ids= string.Join(",", ints.Select(x => x.ToString()).ToArray());// "1,2,3,4,5"

var strQuery = $@"Select PRIO_CATEGORY_ID as PRIO,LANG_ID as LANG, REC_DATE    as REC, REC_USER as RECUSER, RFCH_ID as RFCH,DESCR,COL_DESCR AS COL,ROW_DESCR as DROW,ABBR from STCD_PRIO_CATEGORY_DESCR where REC_USER IN({ids})";

没有“ASP.NET MVC Web服务”。不过有ASP.NET Web API。对不起，这是错误的。没有“ASP.NET MVC Web服务”。但是有ASP.NET Web API。这是错误的，对不起。谢谢Joan，我理解查询部分，但真的不知道如何遍历输入参数数组Hanks Joan，我理解查询部分，但真的不知道如何遍历输入参数数组
