在部分实体类中添加构造函数后出错（Silverlight应用程序）

Question

I have a problem! I am developing silverlight application with ria services. When I added aditional constuctor in entity partial class, I can't initialize class object like:

select new VaultCashOrderQuantity
{
    VaultCashOrderQuantitiesId = Guid.NewGuid(),
    VaultCashOrderId = cashOrder.VaultCashOrderId,
    VaultCurrency = currency,
    VaultCurrencyCode = currency.VaultCurrencyCode,
    VaultCurrencyId = currency.VaultCurrencyId,
    VaultCurrencyDenomination = denomination,
    VaultCurrencyDenominationId = denomination.VaultCurrencyDenominationId,
    Denomination = denomination.Denomination,
    Quantity = 0,
    Summ = 0,
    Amount = 0,
})

Then I added parameterless constructor.Here my two new constructors in partial class:

public partial class VaultCashOrderQuantity
{
    public VaultCashOrderQuantity() { }
    public VaultCashOrderQuantity(CPCashOrderQuantity quantity, Guid cashOrderId)
    {
        VaultCashOrderQuantitiesId = Guid.NewGuid();
        VaultCashOrderId = cashOrderId;
        Denomination = quantity.Denomination;
        Quantity = quantity.Quantity;
        VaultCurrencyId = quantity.VaultCurrencyId;
        //VaultCurrency = quantity.VaultCurrency;
        VaultCurrencyDenominationId = quantity.VaultCurrencyDenominationId;
        //VaultCurrencyDenomination = quantity.VaultCurrencyDenomination;
        Summ = quantity.Summ;
        Amount = quantity.Amount;
    }

On application building I have got error message:

Type 'Vaults.Data.Models.VaultCashOrderQuantity' already defines a member called 'VaultCashOrderQuantity' with the same parameter types

Why I'am getting this error message? How to fix this situation?

I have not tested the same example, but have you tryed to write your partial class without de default constructor?

Like this:

public partial class VaultCashOrderQuantity

{

    public VaultCashOrderQuantity(CPCashOrderQuantity quantity, Guid cashOrderId)
    {
        VaultCashOrderQuantitiesId = Guid.NewGuid();
        VaultCashOrderId = cashOrderId;
        Denomination = quantity.Denomination;
        Quantity = quantity.Quantity;
        VaultCurrencyId = quantity.VaultCurrencyId;
        //VaultCurrency = quantity.VaultCurrency;
        VaultCurrencyDenominationId = quantity.VaultCurrencyDenominationId;
        //VaultCurrencyDenomination = quantity.VaultCurrencyDenomination;
        Summ = quantity.Summ;
        Amount = quantity.Amount;
    }

}

If it does not work, maybe you could try to use this constructor in the ria service class.

In the last case, you could create a method and use it after the class initialization.

I cannot test it right now, that is why i am trying to help with these options, let me know what will happen.
