Oracle UDTs未指定或无效的自定义类型映射

我收到此错误，“未指定'ClassXX'的自定义类型映射或无效是否有可能我的成员值类型不正确以匹配数据库？UDT的Oracle UDTs未指定或无效的自定义类型映射

这里是我的代码：

ClassXX

[OracleCustomTypeMapping("DB.T_OUTERTRAN")] 
public class ClassXX: AOracleCustomObject<ClassXX> 
{ 
    [OracleObjectMapping("OUTERSYSTEMCODE")] 
    public int OuterSystemCode { get; set; } 

    [OracleObjectMapping("TRANSACTIONSOURCE")] 
    public int TransactionSource { get; set; } 

    [OracleObjectMapping("TRANSACTIONTYPE")] 
    public int TransactionType { get; set; } 

    [OracleObjectMapping("AMOUNTCHANGE")] 
    public decimal AmountChange { get; set; } 
    [OracleObjectMapping("REFERENCENO")] 
    public string ReferenceNo { get; set; } 
    [OracleObjectMapping("REMARKS")] 
    public string Remarks { get; set; } 
    [OracleObjectMapping("VENDORID")] 
    public int VendorId { get; set; } 
    [OracleObjectMapping("BUID")] 
    public int BuId { get; set; } 
    [OracleObjectMapping("USERCODE")] 
    public string UserCode { get; set; } 
    [OracleObjectMapping("ACCEPTNEGATIVEBALANCE")] 
    public int AcceptNegativeBalance { get; set; } 

    protected override ClassXX _getObjInstance() 
    { 
     return this; 
    } 
}

AOracleCustomObject：

public abstract class AOracleCustomObject<T> : INullable, IOracleCustomTypeFactory, IOracleCustomType 
{ 
    [IgnoreDataMember] 
    public bool IsNull 
    { 
     get 
     { 
      return false; 
     } 
    } 

    public void FromCustomObject(OracleConnection con, IntPtr pUdt) 
    { 
     T oracleObj = _getObjInstance(); 
     PropertyInfo[] properties = typeof(T).GetProperties(); 
     foreach (PropertyInfo property in properties) 
     { 
      var attrs = (OracleObjectMappingAttribute[]) 
       property.GetCustomAttributes(typeof(OracleObjectMappingAttribute), false); 
      if (attrs.Length > 0) 
      { 
       string attrName = attrs[0].AttributeName; 
       object value = property.GetValue(oracleObj, null); 
       OracleUdt.SetValue(con, pUdt, attrName, value); 
      } 
     } 
    } 

    public void ToCustomObject(OracleConnection con, IntPtr pUdt) 
    { 
     T oracleObj = _getObjInstance(); 
     PropertyInfo[] properties = typeof(T).GetProperties(); 
     foreach (PropertyInfo property in properties) 
     { 
      var attrs = (OracleObjectMappingAttribute[]) 
       property.GetCustomAttributes(typeof(OracleObjectMappingAttribute), false); 
      if (attrs.Length > 0) 
      { 
       string attrName = attrs[0].AttributeName; 
       Type ptype = property.PropertyType; 
       object value = Convert.ChangeType(OracleUdt.GetValue(con, pUdt, attrName), ptype); 
       property.SetValue(oracleObj, value, null); 
      } 
     } 
    } 

    public IOracleCustomType CreateObject() 
    { 
     return (IOracleCustomType)_getObjInstance(); 
    } 

    protected abstract T _getObjInstance(); 
}

的UDT：

create or replace TYPE T_OUTERTRAN AS OBJECT 
( 
    OUTERSYSTEMCODE NUMBER(4,0), 
    TRANSACTIONSOURCE NUMBER(4,0), 
    TRANSACTIONTYPE NUMBER(4,0), 
    AMOUNTCHANGE NUMBER(26,6), 
    REFERENCENO VARCHAR2(50 BYTE), 
    REMARKS VARCHAR2(100 BYTE), 
    VENDORID NUMBER(4,0), 
    BUID NUMBER(5,0), 
    USERCODE VARCHAR2(30 BYTE), 
    ACCEPTNEGATIVEBALANCE NUMBER(1,0) 
);

顺便说一句，我确定数据库连接的用户有权执行对象类型 –

查询如何查看？我测试了你的代码，它运行良好，但值没有映射。包含自定义类型的程序集是否可以加载？ – Husqvik

嗨，实际上，查询sql是PL/SQL，但它确实很复杂。我已经确认类成员和udt是相同的，为什么值不能被映射？对不起，我不太了解你的第二个问题，所有这些代码都在一个dll中，而另一个项目引用了dll，并调用它的方法。 –

我想简单的往返，一切似乎很好地工作。

void Main() 
{ 
    using (var connection = new OracleConnection("DATA SOURCE=HQ_PDB_TCP;PASSWORD=oracle;USER ID=HUSQVIK")) 
    { 
     connection.Open(); 

     using (var command = connection.CreateCommand()) 
     { 
      command.CommandText = "DECLARE i SYS.ODCICOST := :p; BEGIN :p := SYS.ODCICOST(i.CPUCOST + 1, i.IOCOST + 1, i.NETWORKCOST + 1, i.INDEXCOSTINFO || 'Dummy'); END;"; 
      command.BindByName = true; 

      var parameter = command.CreateParameter(); 
      parameter.Direction = ParameterDirection.InputOutput; 
      parameter.ParameterName = "p"; 
      parameter.OracleDbType = OracleDbType.Object; 
      parameter.UdtTypeName = "SYS.ODCICOST"; 
      parameter.Value = new OdciCost { CPUCOST = 123, INDEXCOSTINFO = "DUMMY", IOCOST = 456, NETWORKCOST = 789 }; 
      command.Parameters.Add(parameter); 

      command.ExecuteNonQuery(); 

      var odciCost = (OdciCost)parameter.Value; 
      Console.WriteLine($"CPUCOST={odciCost.CPUCOST}; IOCOST={odciCost.IOCOST}; NETWORKCOST={odciCost.NETWORKCOST}; INDEXCOSTINFO={odciCost.INDEXCOSTINFO}"); 
     } 
    } 
} 

[OracleCustomTypeMapping("SYS.ODCICOST")] 
public class OdciCost : IOracleCustomType, IOracleCustomTypeFactory, INullable 
{ 
    private bool _isNull; 
    [OracleObjectMapping("CPUCOST")] 
    public decimal CPUCOST; 
    [OracleObjectMapping("INDEXCOSTINFO")] 
    public string INDEXCOSTINFO; 
    [OracleObjectMapping("IOCOST")] 
    public decimal IOCOST; 
    [OracleObjectMapping("NETWORKCOST")] 
    public decimal NETWORKCOST; 

    public IOracleCustomType CreateObject() 
    { 
     return new OdciCost(); 
    } 

    public void FromCustomObject(OracleConnection connection, IntPtr pointerUdt) 
    { 
     OracleUdt.SetValue(connection, pointerUdt, "CPUCOST", CPUCOST); 
     OracleUdt.SetValue(connection, pointerUdt, "IOCOST", IOCOST); 
     OracleUdt.SetValue(connection, pointerUdt, "NETWORKCOST", NETWORKCOST); 
     OracleUdt.SetValue(connection, pointerUdt, "INDEXCOSTINFO", INDEXCOSTINFO); 
    } 

    public void ToCustomObject(OracleConnection connection, IntPtr pointerUdt) 
    { 
     CPUCOST = (decimal)OracleUdt.GetValue(connection, pointerUdt, "CPUCOST"); 
     IOCOST = (decimal)OracleUdt.GetValue(connection, pointerUdt, "IOCOST"); 
     NETWORKCOST = (decimal)OracleUdt.GetValue(connection, pointerUdt, "NETWORKCOST"); 
     INDEXCOSTINFO = (string)OracleUdt.GetValue(connection, pointerUdt, "INDEXCOSTINFO"); 
    } 

    public bool IsNull 
    { 
     get { return this._isNull; } 
    } 

    public static OdciCost Null 
    { 
     get { return new OdciCost { _isNull = true }; } 
    } 
}
