Oracle存储过程返回DataSet(多个DataTable)给C#

一、存储过程
CREATE OR REPLACE PROCEDURE GET_SENDEXCEL_XY

二、C#程序接收存储过程

/// <summary>
/// 获取数据
/// </summary>
/// <param name="procName">存储过程名称</param>
/// <param name="conString">数据库连接串</param>
/// <param name="strARR">入参数组</param>
/// <returns></returns>
private DataSet getData(string procName, string conString, params string[] strARR)
{
using (Oracle.ManagedDataAccess.Client.OracleConnection con = new Oracle.ManagedDataAccess.Client.OracleConnection())
{

OracleCommand cmd2 = new OracleCommand();
OracleDataAdapter oda2 = new OracleDataAdapter(cmd2);
OracleParameter par1 = null;
DataSet ds = new DataSet();
con.ConnectionString = 数据库连接串;
con.Open();
cmd2.Connection = con;
cmd2.CommandType = CommandType.StoredProcedure;
cmd2.CommandText = procName;
foreach (string item in strARR)
{
par1 = new OracleParameter(item, OracleDbType.RefCursor);
par1.Direction = ParameterDirection.Output;
cmd2.Parameters.Add(par1);
}
oda2.Fill(ds);
con.Close();
return ds;
}
}
