Question

我的应用程序中有关于数据合同的问题。我的数据库中有5个表，我需要其中3个作为数据类型。所以我创建了一个类，并将所有必需的表解析为[Datacontract]下的类。

这是代码

[DataContract]
public class CustomerDetail
{
    [DataMember]
    public int CustomerID { get; set; }
    [DataMember]
    public string CustomerName { get; set; }
    [DataMember]
    public long ContactNumber { get; set; }
    [DataMember]
    public string Email { get; set; }
    [DataMember]
    public string Address { get; set; }
    [DataMember]
    public string Password { get; set; }
}

[DataContract(Name = "CustomerDetail")]
public class CustomerAccount
{
    [DataMember]
    public int AccountId { get; set; }
    [DataMember ]
    public short PinNo { get; set; }
    [DataMember (Name="CustomerID")]
    public int CustomerID { get; set; }
    [DataMember]
    public int AccountTypeId { get; set; }
    [DataMember]
    public float Amount { get; set; }

}

[DataContract(Name = "CustomerDetail")]
public class TransactionDetail
{
    [DataMember]
    public int TransactionId { get; set; }
    [DataMember (Name ="CustomerID")]
    public int CustomerId { get; set; }
    [DataMember]
    public int AccountId { get; set; }
    [DataMember]
    public int TransactiopnTypeId { get; set; }
    [DataMember]
    public float AmountAfterTransaction { get; set; }
}

我也使用了属性，但是我得到了无效的数据合同异常.. PLZ帮助我解决这个问题。

Answer 1

我认为这是因为您在数据合同中使用了Name参数。您似乎已经剪切并粘贴了这些属性。

只需从DataContract和DataMember属性中删除所有“Name”参数即可。它们对于你正在做的事情并不是必需的，并且会给你带来麻烦。

问题是您为多个对象使用相同的名称“CustomerDetails”。尝试使用此代码代替您的代码（注意：我刚删除了两个Name = CustomerDetail属性）。

 [DataContract]
    public class CustomerDetail
    {
        [DataMember]
        public int CustomerID { get; set; }
        [DataMember]
        public string CustomerName { get; set; }
        [DataMember]
        public long ContactNumber { get; set; }
        [DataMember]
        public string Email { get; set; }
        [DataMember]
        public string Address { get; set; }
        [DataMember]
        public string Password { get; set; }

    }
    [DataContract]
    public class CustomerAccount
    {
        [DataMember]
        public int AccountId { get; set; }
        [DataMember]
        public short PinNo { get; set; }
        [DataMember(Name = "CustomerID")]
        public int CustomerID { get; set; }
        [DataMember]
        public int AccountTypeId { get; set; }
        [DataMember]
        public float Amount { get; set; }

    }

    [DataContract]
    public class TransactionDetail
    {
        [DataMember]
        public int TransactionId { get; set; }
        [DataMember(Name = "CustomerID")]
        public int CustomerId { get; set; }
        [DataMember]
        public int AccountId { get; set; }
        [DataMember]
        public int TransactiopnTypeId { get; set; }
        [DataMember]
        public float AmountAfterTransaction { get; set; }
    }
