wcf 客户端代理生成的类中缺少数据成员订单 [英] Data Member Order is missing from wcf client proxy generated class

问题描述

已将 sql 数据库中的表映射到 Employee dbml 文件中的 linq.

Have mapped table from sql database to linq in Employee dbml file.

[global::System.Runtime.Serialization.DataContractAttribute()]
public partial class tbEmployee
{

    private int _Employeeid;

    private string _EmployeeName;



    public tbEmployee()
    {
    }

    [global::System.Data.Linq.Mapping.ColumnAttribute(Storage = "_Employeeid", DbType = "Int NOT NULL")]
    [global::System.Runtime.Serialization.DataMemberAttribute(Order = 0)]
    public int EmployeeID
    {
        get
        {
            return this._PeriodContextRefId;
        }
        set
        {
            if ((this._Employeeid != value))
            {
                this._Employeeid = value;
            }
        }
    }

    [global::System.Data.Linq.Mapping.ColumnAttribute(Storage = "_EmployeeName", DbType = "NVarChar(2) NOT NULL", CanBeNull = false)]
    [global::System.Runtime.Serialization.DataMemberAttribute(Order = 1)]
    public string EmployeeName
    {
        get
        {
            return this._EmployeeName;
        }
        set
        {
            if ((this._EmployeeName != value))
            {
                this._EmployeeName = value;
            }
        }
    }

}

在 Service 中，我只是返回类型为

and in Service i am just returning the object of type

List<tbEmployee>

当我在客户端中添加服务引用时，日期成员订单信息正在跳过.

when i add the service reference in my client the date member order information is skipping.

当我使用 protobuf-net 进行序列化/反序列化时，它出现了问题在我的客户端反序列化时.

as i am using the protobuf-net for serialization/deserialization it is giving the problem while deserializing at my client side.

推荐答案

是的，这很麻烦.有 2 个选项可以解决这个问题；第一个(也是最简单的)是使用 WCF 在客户端和服务器之间共享合约程序集的能力.如果您可以共享 DTO 层，那将使事情变得简单.

Yes, that is a nuisance. There are 2 options for fixing this; the first (and easiest) is to use WCF's ability to share a contract assembly between client and server. If you can share the DTO layer, that'll keep things simple.

第二种是在客户端添加额外的标记以提供线索.您可以通过 partial 类来完成此操作，例如在 separate 代码文件中(不要编辑生成的文件):

The second is to add additional markers at the client to give it a clue. You can do this via a partial class, for example in a separate code file (don't edit the generated file):

namespace YourNamespace {
    [ProtoContract(DataMemberOffset = 1)] /* shift all DataMember orders */
    public partial class tbEmployee {}
}

更明确的替代方法是:

namespace YourNamespace {
    [ProtoPartialMember(1, "EmployeeID")]
    [ProtoPartialMember(2, "EmployeeName")]
    public partial class tbEmployee {}
}
