asp.net webserver 中 XmlElement 的使用

1.建立一個ToosTemp.asmx文件

2.其中定義一個方法，取得產品的分類：

        [WebMethod(EnableSession = true, Description = "取得商品分類")]
        public GetProdClasssResponse GetProdClass(string merchantUid, string ShopCode)
        {
            GetProdClassBll bllGetProdClass = new GetProdClassBll();
            return bllGetProdClass.GetProdClass(merchantUid, ShopCode);
        }

3.建立輸出GetProdClasssResponse實體：

    [Serializable]

    [XmlRoot("GetProdClasssResponse")]  

    public class GetProdClasssResponse

    {

        private GetProdClass getProdClass;



        public GetProdClass GetProdClass {

            set { getProdClass = value; }

            get { return getProdClass; }

        }

    }

4.建立其他實體，使用到的：

View Code

    public class GetProdClass

    {

        private bool _ResultType;



        public bool ResultType

        {

            get { return _ResultType; }

            set { _ResultType = value; }

        }



        private string _ErrorCode;



        public string ErrorCode

        {

            get { return _ErrorCode; }

            set { _ErrorCode = value; }

        }

        private string _ErrorMsg;



        public string ErrorMsg

        {

            get { return _ErrorMsg; }

            set { _ErrorMsg = value; }

        }

        private List<ProProdClass> _ProdClass;



        [XmlElement(ElementName = "ProdClass")]

        public List<ProProdClass> ProdClass

        {

            set

            { _ProdClass = value; }

            get {

                return _ProdClass;

            }

        }

    }



    public class ProProdClass

    {

        private string _ID;



        public string ID

        {

            get { return _ID; }

            set { _ID = value; }

        }

        private string _ClassName;



        public string ClassName

        {

            get { return _ClassName; }

            set { _ClassName = value; }

        }

        private string _Parent;



        public string Parent

        {

            get { return _Parent; }

            set { _Parent = value; }

        }

        private int _Kind;



        public int Kind

        {

            get { return _Kind; }

            set { _Kind = value; }

        }



    }

5.如果沒有  [XmlElement(ElementName = "ProdClass")] 這句：

生成的xml如下：

View Code

<?xml version="1.0" encoding="utf-8"?>

<GetProdClasssResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/">

        <Kind>2</Kind>

      </ProProdClass>

    </ProdClass>

  </GetProdClass>

</GetProdClasssResponse>

6.如果加上后，生成的如下：

View Code

<?xml version="1.0" encoding="utf-8"?>

<GetProdClasssResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/">

    </ProdClass>

  </GetProdClass>

</GetProdClasssResponse>

7.對比如下：

如果有這個語句，生成的xml是少一個實體的。可以把list定義的實體給去掉。

8. [XmlElement(ElementName = "ProdClass1")] 可以定義輸出的實體名稱

        private List<ProProdClass> _ProdClass;

        [XmlElement(ElementName = "ProdClass1")]
        public List<ProProdClass> ProdClass
        {
            set
            { _ProdClass = value; }
            get {
                return _ProdClass;
            }
        }

這樣的語句，會輸出一個一個 ProdClass1實體。
