Question

有一项服务已迁移到WCF。大多数方法都有int，string，DateTime参数，一切正常，但是一个方法接收一组自定义类对象。

[DataContract]
public class Term
{
    [DataMember]
    public DateTime Date;
    [DataMember]
    public decimal Amount;
}

//

public int UpdateTerm(int id, int documentId, Term[] terms)
{
  // it receives the passed Term array with all objects 
  // but here all the Dates are 01.01.0001 and all Amounts are 0.00
}

我在界面中添加了所有ServiceContract，OperationContract属性。为什么Dates 01.01.0001和Amounts 0.00，就像阵列成员再次构建一样？其他服务工作正常，没有任何具体的......

简化的客户端代码：

Term[] terms = new Term[3];
for (int i = 0; i < rows.Length; ++i)
{
  terms[i] = new Term();
  terms[i].Amount = 10;
  terms[i].Date = DateTime.Now;
}

MyService service = new MyService();
try
{
  id = service.UpdateTerm(1, 2, terms);
  service.Close();
}
catch
{
  service.Abort();
  throw;
}

我们遇到了类似的问题。尝试更新*** Specified属性，看看是否有效。它为我们做了：

Term[] terms = new Term[3];
for (int i = 0; i < rows.Length; ++i)
{
  terms[i] = new Term();
  terms[i].Amount = 10;
  terms[i].Date = DateTime.Now;
  terms[i].AmountSpecified = true;
  terms[i].DateSpecified = true;
}

WCF服务接收不正确的参数数据
