使用svcutil.exe從xsd文件生成類時發出問題

Question

我正在使用svcutil.exe工具在WCF服務之間共享DataContracts

我在庫中定義了[DataMembar] 。 為了共享數據合同，我將DataContract.dll轉換為DataContract.xsd文件。

命令是

svcutil /dconly <my DataContractDLL path>

生成.xsd后，我使用該命令從DataContract.xsd生成類文件

svcutil /dconly /language:CS DataContract.xsd /out:ClientDataContracts.cs

每件事都很順利，並在上面的步驟中工作。

面臨的問題：

我在我的DataContract.dll庫的一個實體中添加了Dictionary *類型，如下所示（即我添加了Dictionary類型的TimeLogs DataMember 。）

public partial class RecordDto
{
    /// <summary>
    /// Gets or sets the Comment.
    /// </summary>
    /// <value>Insurance Company.</value>
    [WcfSerialization::DataMember(Name = "InsuranceCompany", IsRequired = false, Order = 25)]
    public InsuranceCompanyDto InsuranceCompany { get; set; }

    [WcfSerialization::DataMember(Name = "TimeLogs", IsRequired = false, Order = 26)]
    public Dictionary<String, DateTime> TimeLogs
    {
        get;
        set;
    }
}

添加Dictionary類型后，我開始在將.xsd轉換為.cs遇到錯誤：

添加Dictionary類型后，為什么我收到錯誤？

我該如何解決？

接口IDictionary不可序列化，您應該像這樣實現自己的字典

[XmlRoot("dictionary")]
public class SerializableDictionary<TKey, TValue>
    : Dictionary<TKey, TValue>, IXmlSerializable
{
    public System.Xml.Schema.XmlSchema GetSchema()
    {
        return null;
    }

    public void ReadXml(System.Xml.XmlReader reader)
    {
        XmlSerializer keySerializer = new XmlSerializer(typeof(TKey));
        XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue));

        bool wasEmpty = reader.IsEmptyElement;
        reader.Read();

        if (wasEmpty)
            return;

        while (reader.NodeType != System.Xml.XmlNodeType.EndElement)
        {
            reader.ReadStartElement("item");
            reader.ReadStartElement("key");
            TKey key = (TKey)keySerializer.Deserialize(reader);
            reader.ReadEndElement();

            reader.ReadStartElement("value");
            TValue value = (TValue)valueSerializer.Deserialize(reader);
            reader.ReadEndElement();

            this.Add(key, value);
            reader.ReadEndElement();
            reader.MoveToContent();
        }
        reader.ReadEndElement();
    }

    public void WriteXml(System.Xml.XmlWriter writer)
    {
        XmlSerializer keySerializer = new XmlSerializer(typeof(TKey));
        XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue));

        foreach (TKey key in this.Keys)
        {
            writer.WriteStartElement("item");
            writer.WriteStartElement("key");

            keySerializer.Serialize(writer, key);
            writer.WriteEndElement();

            writer.WriteStartElement("value");
            TValue value = this[key];
            valueSerializer.Serialize(writer, value);
            writer.WriteEndElement();

            writer.WriteEndElement();
        }
    }
}

希望這可以幫助。
