3层Silverlight体系结构 [英] 3-tier Silverlightarchitecture

问题描述

如果任何人有3层Silverlightarchitecture的任何演示项目，请给我.我是这些Silverlight架构的新手. alredy创建的sliverlight启用像这样的wcf服务，我在其中有一类rrf1 公共课程RRF1 { [DataMember] 公共列表< ddllocation> LocationList {get;放; } } 我开了一堂课.我实施的 [数据合同] 公共类ddlLocation { private int _key; 私有字符串_value; [DataMember] 公钥 { 得到 { 返回_key; } 放 { _key =值； } } [DataMember] 公共字符串值 { 得到 { 返回_value; } 放 { _value =值； } } } 和宣言 #region方法声明 [服务合约] 公共接口IRRFInsert { [运营合同] List< ddllocation> getLocationDropdown(); } 和我用 #region将位置值输入下拉菜单 公共列表< ddllocation> getLocationDropdown() { List< ddllocation> ddlLocationList = new List< ddllocation>(); SqlConnection objCon =新的SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings ["ConnStr"].ToString()); DataSet dsLocation = new DataSet(); SqlCommand cmdLocation =新的SqlCommand(); cmdLocation.Connection = objCon; cmdLocation.CommandText ="usp_Synapse_REC_GetddlLocation"; cmdLocation.CommandType = CommandType.StoredProcedure; SqlDataAdapter adaLocation =新的SqlDataAdapter(cmdLocation); //从sip_Location_master ORDER BY LOCATION_NAME中选择LOCATION_ID_PK，LOCATION_NAME" 尝试 { objCon.Open(); adaLocation.Fill(dsLocation); for(int i = 0; i< dsLocation.Tables [0] .Rows.Count; i ++) { ddlLocation obj = new ddlLocation(); obj.Key = Convert.ToInt32(dsLocation.Tables [0] .Rows ["LOCATION_ID_PK"]);; obj.Value = dsLocation.Tables [0] .Rows ["LOCATION_NAME"].ToString(); ddlLocationList.Add(obj); } } 抓住 { } 最后 { cmdLocation.Dispose(); objCon.Close(); objCon.Dispose(); } 返回ddlLocationList; } #endregion 和我给客户端bin的引用..它工作正常..但我不想每次都不想这样创建连接，命令..等..我想要一个框架层，业务层，服务层避免单层.我想你有我的问题:P.请帮助我

If any one has any demo project of 3-tier Silverlightarchitecture , Please give me. I am new to these Silverlight architecture. alredy created sliverlight enable wcf service like this i have one class rrf1 in that public class RRF1 { [DataMember] public List<ddllocation> LocationList { get; set; } } i created one class . that i implemented in [DataContract] public class ddlLocation { private int _key; private string _value; [DataMember] public int Key { get { return _key; } set { _key = value; } } [DataMember] public string Value { get { return _value; } set { _value = value; } } } and Declaration #region Method Declaration [ServiceContract] public interface IRRFInsert { [OperationContract] List<ddllocation> getLocationDropdown(); } and i used #region Getting Location Values in to the dropdown public List<ddllocation> getLocationDropdown() { List<ddllocation> ddlLocationList = new List<ddllocation>(); SqlConnection objCon = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnStr"].ToString()); DataSet dsLocation = new DataSet(); SqlCommand cmdLocation = new SqlCommand(); cmdLocation.Connection = objCon; cmdLocation.CommandText = "usp_Synapse_REC_GetddlLocation"; cmdLocation.CommandType = CommandType.StoredProcedure; SqlDataAdapter adaLocation = new SqlDataAdapter(cmdLocation); //"select LOCATION_ID_PK, LOCATION_NAME from sip_Location_master ORDER BY LOCATION_NAME" try { objCon.Open(); adaLocation.Fill(dsLocation); for (int i = 0; i < dsLocation.Tables[0].Rows.Count; i++) { ddlLocation obj = new ddlLocation(); obj.Key = Convert.ToInt32(dsLocation.Tables[0].Rows["LOCATION_ID_PK"]); obj.Value = dsLocation.Tables[0].Rows["LOCATION_NAME"].ToString(); ddlLocationList.Add(obj); } } catch { } finally { cmdLocation.Dispose(); objCon.Close(); objCon.Dispose(); } return ddlLocationList; } #endregion and i gave ref to client bin.. it''s working fine.. but i don''t want like this every time i don''t want creat connect,command.. ect.. that want i want one framework layer , bussness layer, sevice layer to avoid single layer . i think u got my question :P . please help me
