Question

我想创建一个DataContract，它是一个包含2个不同List成员的类。当我尝试启动Web服务时，我收到测试WCF客户端不支持我的方法SendEmail的错误。这是我的数据合同：

 [DataContract]
[KnownType(typeof(int[]))]
public class EmailInfo
{
    private string strFromUserID = string.Empty;
    private string strFromAddress = string.Empty;
    private string strFromName = string.Empty;
    private object lstIndividualIDs = null;
    private object lstGroupIDs = null;
    private string strSubject = string.Empty;
    private string strMessage = string.Empty;

    [DataMember]
    public string FromUserID
    {
        get { return strFromUserID; }
        set { strFromUserID = value; }
    }

    [DataMember]
    public string FromAddress
    {
        get { return strFromAddress; }
        set { strFromAddress = value; }
    }

    [DataMember]
    public string FromName
    {
        get { return strFromName; }
        set { strFromName = value; }
    }

    [DataMember]
    public object IndividualIDs
    {
        get { return lstIndividualIDs; }
        set { lstIndividualIDs = value; }
    }

    [DataMember]
    public object GroupIDs
    {
        get { return lstGroupIDs; }
        set { lstGroupIDs = value; }
    }

    [DataMember]
    public string Subject
    {
        get { return strSubject; }
        set { strSubject = value; }
    }

    [DataMember]
    public string Message
    {
        get { return strMessage; }
        set { strMessage = value; }
    }
}

这是我使用DataContract的方法：

 public string SendEmail(EmailInfo emailInfo)
    {
        string tstrErrorMsg = string.Empty;
        SqlConnection SqlConn = null;
        try
        {
            return tstrErrorMsg;
        }
        catch (Exception ex)
        {
            return null;
        }
        finally
        {
            if (SqlConn != null)
            {
                SqlConn.Close();
            }
        }
    }

我想在DataContract中有一个类型为List的DataMember。如何将该类型添加到DataContract？

Answer 1

我通过将lstIndividualIDs和listGroupIDs更改为List来运行Web服务。我以为我必须使用物体。万一有其他人有这个问题...

object lstIndividualIDs - ＆gt;列表listIndividualIDs 与GroupID相同。这允许测试客户端运行服务..

如何将List <int>添加到Web服务的DataContract </int>
