Oracle UDTs未指定或無效的自定義類型映射

我收到此錯誤，「未指定'ClassXX'的自定義類型映射或無效是否有可能我的成員值類型不正確以匹配數據庫？UDT的Oracle UDTs未指定或無效的自定義類型映射

這裏是我的代碼：

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) 
);

順便說一句，我確定數據庫連接的用戶有權執行對象類型 –

查詢如何查看？我測試了你的代碼，它運行良好，但值沒有映射。包含自定義類型的程序集是否可以加載？ – Husqvik

嗨，實際上，查詢sql是PL/SQL，但它確實很複雜。我已經確認類成員和udt是相同的，爲什麼值不能被映射？對不起，我不太瞭解你的第二個問題，所有這些代碼都在一個dll中，而另一個項目引用了dll，並調用它的方法。 –

我想簡單的往返，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 }; } 
    } 
}
