－－看看本空间读取上传文件的内容(不保存)－－
项目要求：(简单点讲)
1、客户端通过web站点上传XML，XML文件在web站点首先解析成DataSet，所以上传给WebService只是DataSet，你也可以上传XML文件到WebService服务器，这里以前者为例。
2、WebService接收客户端传来的DataSet，将DataSet插入到数据库。
3、客户端查询，通过web引用，查询结果返回客户端。
-------最先要解决的问题是你要阅读和了解WebService相关的知识------
第一步：创建你的webservice，打开VS2005---新建网站----Asp.Net Web服务---确定
第二步：网站自动给你生成了一个asmx文件----现在你就可以运行这个简单的webservice，之后你就可以看到那个"Hello World"。
第一步：创建你的WebSite，就是asp.net站点
//当然开发前,你可以先不新建asp.net站点，我就直接在webservice本地操作，我觉得这样比较好。
1：【上传功能】
第一步：在你的web站点拖入一个上传控件FileUpload，这个控件的作用就是选择本地的xml文件，在本地转化为dataset，你要传给webservice的是dataset。具体代码如下：
//=================客户端上传Xml文件====================
protected void btnUpload_Click(object sender, EventArgs e)
{
//fullfileName获得全路径
string fullfileName = this.fileUpload.PostedFile.FileName;
//获得文件名
fileName = fullfileName.Substring(fullfileName.LastIndexOf("\\") + 1);
//文件类型
string fileType = fullfileName.Substring(fullfileName.LastIndexOf(".") + 1);
if (this.fileUpload.PostedFile.FileName != null)
{
if (fileType.ToLower() == "xml")
{
DataSet ds = new DataSet();
ds.ReadXml(fullfileName);
//调用webService中的方法.
myService.getXml(ds);
//成功后提示，代码省略
}
else
{
//失败后提示，代码省略
}
}
else
{
this.lblMessage.Text = "请选择你要上传的文件,谢谢!";
}
}
你在站点上上传了一个dataset，所以webservice就要有一个方法来接收它，代码如下：
//================上传XML文件===================
[WebMethod]
public bool getXml(DataSet dataSet)
//public DataSet getXml(DataSet dataSet)
{
//连接数据库，这里面随你怎么连接数据库，只要能连上就可以了。
DB db = new DB();
SqlConnection con = db.sqlCon();
con.Open();
DataSet c_dataSet = new DataSet();
//将用户传过来的dataSet赋值给c_dataSet.
c_dataSet = dataSet;
//这里调用了存储过程.
//读者只要将sp_MVP改为select * from MVP,其它的照例,不用存储管理的话把蓝色那行都删掉.
SqlDataAdapter sda = new SqlDataAdapter("sp_MVP",con);
sda.SelectCommand.CommandType = CommandType.StoredProcedure;
SqlCommandBuilder mysqlcommand = new SqlCommandBuilder(sda);
sda.Update(c_dataSet, "MVP");
SqlDataAdapter sda1 = new SqlDataAdapter("sp_OtherCompetencies", con);
sda1.SelectCommand.CommandType = CommandType.StoredProcedure;
SqlCommandBuilder mysqlcommand1 = new SqlCommandBuilder(sda1);
sda1.Update(c_dataSet, "OtherCompetencies");
SqlDataAdapter sda2 = new SqlDataAdapter("sp_OtherCompetency", con);
sda2.SelectCommand.CommandType = CommandType.StoredProcedure;
SqlCommandBuilder mysqlcommand2 = new SqlCommandBuilder(sda2);
sda2.Update(c_dataSet, "OtherCompetency");
SqlDataAdapter sda3 = new SqlDataAdapter("sp_Publications", con);
sda3.SelectCommand.CommandType = CommandType.StoredProcedure;
SqlCommandBuilder mysqlcommand3 = new SqlCommandBuilder(sda3);
sda3.Update(c_dataSet, "Publications");
SqlDataAdapter sda4 = new SqlDataAdapter("sp_Publication", con);
sda4.SelectCommand.CommandType = CommandType.StoredProcedure;
SqlCommandBuilder mysqlcommand4 = new SqlCommandBuilder(sda4);
sda4.Update(c_dataSet, "Publication");
//处理所以的请求(更新).
c_dataSet.AcceptChanges();
con.Close();
return true;
}
首先要在webservice服务器建立数据库，有五张表MVP,OtherCompetencies......这里webservice要连接数据库了，这里是连接sql2005，o(∩_∩)o...哈哈，我相信这里连接数据库会让你很郁闷的，实在没辙了来找我,^_^
现在就可以试试效果了！当然不可以一下就能成功，多调试！
2：[查询功能]
查询是在webservice里面实现的，代码如下：
//=================用户查询=====================
[WebMethod]
//public DataSet searchData(string mvpguid,string fristname,string lastname)
public DataSet searchData(string mvpguid)
{
//连接数据库
DB dataBase = new DB();
SqlConnection con = dataBase.sqlCon();
con.Open();
//用户查询得到的将是myDataSet.
DataSet myDataSet = new DataSet();
try
{
SqlDataAdapter myAdapter = new SqlDataAdapter();
if (mvpguid != "")
{
//按照用户输入的mvpguid进行查询.
myAdapter.SelectCommand = new SqlCommand("select * from MVP where MVPGUID='"+mvpguid+"'", con);
SqlCommandBuilder myCB = new SqlCommandBuilder(myAdapter);
myAdapter.Fill(myDataSet, "MVP");
//建立表间关系.
SqlDataAdapter myAdapter1 = new SqlDataAdapter("select OtherCompetencies.OtherCompetencies_Id,OtherCompetencies.MVP_Id from MVP,OtherCompetencies where MVP.MVP_Id=OtherCompetencies.MVP_Id and MVP.MVPGUID='" + mvpguid + "'", con);
SqlCommandBuilder myCB1 = new SqlCommandBuilder(myAdapter1);
myAdapter1.Fill(myDataSet, "OtherCompetencies");
SqlDataAdapter myAdapter2 = new SqlDataAdapter("select OtherCompetency.OtherCompetencies_Id,OtherCompetency.OtherCompetency_Text from MVP,OtherCompetencies,OtherCompetency where MVP.MVP_Id=OtherCompetencies.MVP_Id and OtherCompetencies.OtherCompetencies_Id=OtherCompetency.OtherCompetencies_Id and MVP.MVPGUID='" + mvpguid + "'", con);
SqlCommandBuilder myCB2 = new SqlCommandBuilder(myAdapter2);
myAdapter2.Fill(myDataSet, "OtherCompetency");
SqlDataAdapter myAdapter3 = new SqlDataAdapter("select Publications.Publications_Id,Publications.MVP_Id from Publications,MVP where MVP.MVP_Id=Publications.MVP_Id and MVP.MVPGUID='" + mvpguid + "'", con);
SqlCommandBuilder myCB3 = new SqlCommandBuilder(myAdapter3);
myAdapter3.Fill(myDataSet, "Publications");
SqlDataAdapter myAdapter4 = new SqlDataAdapter("select Publication.Publications_Id,Publication.Id,Publication.Title,Publication.Publisher,Publication.DatePublished,Publication.Abstract,Publication.UrlLink from MVP,Publications,Publication where MVP.MVP_Id=Publications.MVP_Id and Publications.Publications_Id=Publication.Publications_Id and MVP.MVPGUID='" + mvpguid + "'", con);
SqlCommandBuilder myCB4 = new SqlCommandBuilder(myAdapter4);
myAdapter4.Fill(myDataSet, "Publication");
//Create DataRelation, and add it to the DataSet.
DataRelation dr = new DataRelation("MVPToOtherCompetencies", myDataSet.Tables["MVP"].Columns["MVP_Id"],
myDataSet.Tables["OtherCompetencies"].Columns["MVP_Id"]);
DataRelation dr1 = new DataRelation("OtherCompetenciesToOtherCompetency", myDataSet.Tables["OtherCompetencies"].Columns
["OtherCompetencies_Id"], myDataSet.Tables["OtherCompetency"].Columns["OtherCompetencies_Id"]);
DataRelation dr2 = new DataRelation("MVPToPublications", myDataSet.Tables["MVP"].Columns["MVP_Id"], myDataSet.Tables
["Publications"].Columns["MVP_Id"]);
DataRelation dr3 = new DataRelation("PublicationsToPublication", myDataSet.Tables["Publications"].Columns["Publications_Id"],
myDataSet.Tables["Publication"].Columns["Publications_Id"]);
//获取或设置一个指示DataRelation对象是否嵌套的值.
dr.Nested = true;
dr1.Nested = true;
dr2.Nested = true;
dr3.Nested = true;
//创建关系到集合中
myDataSet.Relations.Add(dr);
myDataSet.Relations.Add(dr1);
myDataSet.Relations.Add(dr2);
myDataSet.Relations.Add(dr3);
}
}
catch (SqlException exception)
{
return DataError(exception);
}
return myDataSet;
}
//====================错误信息=======================
public DataSet DataError(Exception ex)
{
DataSet errDS = new DataSet("Errors");
DataTable errTable = errDS.Tables.Add("Error");
errTable.Columns.Add("Message");
errTable.Rows.Add(new Object[] { ex.Message });
return errDS;
}
代码有点多，呵呵，然后你在客户端只要引用它的接口就可以了，这样会更好理解一点，代码如下：
//====================客户端查询函数=====================
protected void btnSearch_Click1(object sender, EventArgs e)
{
string c_mvpGuid = "";
try
{
c_mvpGuid = this.txtByMVPGUID.Text.ToString();
//getDataSet对象获得查询返回的ds.
DataSet getDataSet = myService.searchData(c_mvpGuid);
///查询默认显示为MVP表.测试的时候在index.aspx页面上显示.
this.dgResult.DataSource = getDataSet.Tables["MVP"].DefaultView;
this.dgResult.DataBind();
}
catch (Exception ex)
{
throw ex;
}
}
要是有什么不懂的地方，你可以留言，我会给你答复。^_^
呵呵，忘了一件事，如果你用自己的xml文件，自己的数据库，那就没事了，不是的话看看：
<?xml version="1.0" encoding="utf-8"?>
<MVPData>
<MVP>
<MVPGUID>f8433e20-c9af-4b48-9c83-2fc235393f31</MVPGUID>
