水晶易表调用C#的WebService,返回数据集合的应用分析

1. 水晶易表不能识别WS接口返回的DataTable或DataSet数据类型，会提示“无法加载URL”

3. C#调用Oracle的Package，并返回数据列表

2. 经查证，可以接受string类型的，如果需要返回数据列表，那么需要借助数组来返回，代码实现如下：

public WeekSale_Table GetData(string skc1, string skc2, string week1, string week2, string week3, string week4)
 {
 try
 {
　　　　　　　　　//C#调用Oracle的包，返回数据列表
 OracleConnection orcn = new OracleConnection(ConfigurationManager.AppSettings["SAPBI"].ToString());
 OracleCommand cmd = new OracleCommand("pkg_cx_Productlifecycle.skcweeksale", orcn);
 cmd.CommandType = CommandType.StoredProcedure;
 OracleParameter ip0 = new OracleParameter("skc1", OracleType.VarChar);
 OracleParameter ip1 = new OracleParameter("skc2", OracleType.VarChar);
 OracleParameter ip2 = new OracleParameter("week1", OracleType.VarChar);
 OracleParameter ip3 = new OracleParameter("week2", OracleType.VarChar);
 OracleParameter ip4 = new OracleParameter("week3", OracleType.VarChar);
 OracleParameter ip5 = new OracleParameter("week4", OracleType.VarChar);

 ip0.Value = skc1;
 ip1.Value = skc2;
 ip2.Value = week1;
 ip3.Value = week2;
 ip4.Value = week3;
 ip5.Value = week4;
 cmd.Parameters.Add(ip0);
 cmd.Parameters.Add(ip1);
 cmd.Parameters.Add(ip2);
 cmd.Parameters.Add(ip3);
 cmd.Parameters.Add(ip4);
 cmd.Parameters.Add(ip5);
 OracleParameter p1 = new OracleParameter("p_rc", OracleType.Cursor);
 p1.Direction = System.Data.ParameterDirection.Output;
 cmd.Parameters.Add(p1);
 OracleDataAdapter command = new OracleDataAdapter(cmd);
 DataSet ds = new DataSet();
 command.Fill(ds, "Table");
 DataTable dt = ds.Tables["Table"];
 WeekSale_Table wt = new WeekSale_Table();
 wt.row = new WeekSale_Row[dt.Rows.Count];
 int rcount = dt.Rows.Count;
 for (int i = 0; i < rcount; i++)
 {
 DataRow dr = dt.Rows[i];
 WeekSale_Row row = new WeekSale_Row();
 row.DISCOUNT1 = dr["DISCOUNT1"].ToString();
 row.DISCOUNT2 = dr["DISCOUNT2"].ToString();
 row.FCALCSUMS1 = dr["FCALCSUMS1"].ToString();
 row.FCALCSUMS2 = dr["FCALCSUMS2"].ToString();
 row.NUMS1 = dr["NUMS1"].ToString();
 row.NUMS2 = dr["NUMS2"].ToString();
 row.SKC1 = dr["SKC1"].ToString();
 row.SKC2 = dr["SKC2"].ToString();
 row.WEEK = dr["WEEK"].ToString();
 row.WEEKS = dr["WEEKS"].ToString();
 wt.row[i] = row;
 }
 return wt;
 }
 catch
 {
 return null;
 }
 }

//定义Row，一行
public class WeekSale_Row
 {
 public string WEEKS;
 public string SKC1;
 public string SKC2;
 public string FCALCSUMS1;
 public string FCALCSUMS2;
 public string NUMS1;
 public string NUMS2;
 public string DISCOUNT1;
 public string DISCOUNT2;
 public string WEEK;
 }

//定义Table
public class WeekSale_Table
 {
 public WeekSale_Row[] row;
 }
