pocketpc中嵌入xml文件

例如，我们需要读取users.xml中的数据，一种比较笨的方法是，将users.xml直接拷到pda上，但是这种方法并不通用，我们可以借鉴透明按钮的方法，把他作为嵌入的资源，这个所谓的嵌入的资源就是当部署的时候，会直接部署到pda上，不需要拷贝进去。

=======================================

第一种方法，我们直接拷到pda上：

=========================================

           Cursor.Current = Cursors.WaitCursor;
            DataSet ds = new DataSet();
            ds.ReadXml((@"/users.xml"));//这时我们把users.xml存放在/下
            int count = ds.Tables["user"].Rows.Count;  //看表中有多少个user                  
            operateData.createFile("MobileLawEn.sdf");
            if (ds != null && count > 0)
            {
                checkTableExistance("users");
                SqlCeConnection conn = new SqlCeConnection(operateData.connStr);
                SqlCeCommand cmd = new SqlCeCommand(
                 "create table users(username nvarchar(20),password nvarchar(20),deptid   int,constraint p_key primary key(username,deptid))", conn);
                conn.Open();
                int rst = cmd.ExecuteNonQuery();
                Cursor.Current = Cursors.Default;
                for (int i = 0; i < count; i++)
                {
                    string name = ds.Tables["user"].Rows[i]["username"].ToString();

//读取第i个user中的用户名

                    string password = ds.Tables["user"].Rows[i]["password"].ToString();
                    string deptid = ds.Tables["user"].Rows[i]["deptid"].ToString();
                    string sql = "insert into users (username,password,deptid) values ('" + name + "','" + password + "'," + deptid + ")";
                    SqlCeCommand comm = new SqlCeCommand(sql, conn);
                    comm.ExecuteNonQuery();
                }

                conn.Close();
                Cursor.Current = Cursors.Default;

============================================

第二种方法：我们将xml文件作为嵌入的资源：

=============================================

 首先嵌入：

 Cursor.Current = Cursors.WaitCursor;
            DataSet ds = null;
            ds = new DataSet();
            System.IO.Stream strm = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("MobileLawEn.xml.users.xml");

//GetManifestResourceStream是用来加载制定的资源。
            ds.ReadXml(strm, System.Data.XmlReadMode.InferSchema);

//System.Data.XmlReadMode.InferSchema用来设置这种模式：

InferSchema

忽略任何嵌入式架构，并从 XML 数据推断架构

 

            int count = ds.Tables["user"].Rows.Count;  //看表中有多少个user        
            operateData.createFile("MobileLawEn.sdf");
            if (ds != null && count > 0)
            {
                checkTableExistance("users");
                SqlCeConnection conn = new SqlCeConnection(operateData.connStr);
                SqlCeCommand cmd = new SqlCeCommand(
                 "create table users(username nvarchar(20),password nvarchar(20),deptid int,constraint p_key primary key(username,deptid))", conn);
                conn.Open();
                int rst = cmd.ExecuteNonQuery();
                Cursor.Current = Cursors.Default;
                for (int i = 0; i < count; i++)
                {
                    string name = ds.Tables["user"].Rows[i]["username"].ToString();//读取第i个user中的用户名
                    string password = ds.Tables["user"].Rows[i]["password"].ToString();

//读取第i个user中的密码
                    string deptid = ds.Tables["user"].Rows[i]["deptid"].ToString();
                    string sql = "insert into users (username,password,deptid) values ('" + name + "','" + password + "'," + deptid + ")";
                    SqlCeCommand comm = new SqlCeCommand(sql, conn);
                    comm.ExecuteNonQuery();
                }

                conn.Close();
                Cursor.Current = Cursors.Default;
