开发小工具的原因：
1、我们公司的开发是客户端用C#，服务端用Java，前后台在通讯交互的时候，会用到Oracle数据库的字段，因为服务器端有公司总经理开发的一个根据Oracle数据库的表生成的class文件，每次都是等服务端都写好了实体类以后，我们再复制、粘贴，修改字段的类型为string，因为在生成的时候，是根据Oracle数据库里的字段类型生成的java文件，但是我们在前后台通信的时候，为了不失精度的一些问题，一般都用string类型来传递，因此每次修改都比较费事。
2、VS2015在封装字段的时候，不会像2012一样，在字段的下方，而是统一的封装到一起，即字段都在上方，属性统一的在下方。
小工具界面效果：
这个是刚打开小工具的页面，连接按钮上面的几个Textbox就是连接数据库时需要的参数。
连接成功以后，把上面的连接部分隐藏掉，为了能有一个稍微大一点的空间，左侧用的是TreeView，父节点是表的Owner，子节点是表
点击左侧TreeView的父节点，则其拥有的表全部显示在右侧
点击左侧的子节点，则显示出来，这个表具体有哪些字段，要生成的VO里的字段就是指这些字段。
NameSpace是指要生成的文件的命名空间，如果不输入，则默认Test，点击生成VO，则会同时生成两个文件，在不同的文件夹下，一个带通知机制，一个不带通知机制，需要哪个是根据实际情况来定。
开发过程：
1、要连接数据库，则自然要有连接数据库的实体类
public class ConnVo : ObjectNotifyPropertyChanged
{
private string connIP;//ip地址
private string connPort;//端口
private string connSid;//服务器名称
private string connUser;//用户名
private string connPwd;//密码 public string ConnIP
{
get
{
return connIP;
} set
{
connIP = value;
RaisePropertyChanged("ConnIP");
}
} public string ConnPort
{
get
{
return connPort;
} set
{
connPort = value;
RaisePropertyChanged("ConnPort");
}
} public string ConnSid
{
get
{
return connSid;
} set
{
connSid = value;
RaisePropertyChanged("ConnSid");
}
} public string ConnUser
{
get
{
return connUser;
} set
{
connUser = value;
RaisePropertyChanged("ConnUser");
}
} public string ConnPwd
{
get
{
return connPwd;
} set
{
connPwd = value;
RaisePropertyChanged("ConnPwd");
}
}
}
ConnVo
2、因为是对Oracle进行操作，因此数据库连接、Select语句神马的肯定少不了，因此专门有一个数据库操作类
public class DBHelper
{
/// <summary>
/// 声明连接
/// </summary>
protected static OracleConnection Connection; /// <summary>
/// 返回Connection
/// </summary>
/// <param name="ip">地址</param>
/// <param name="port">端口</param>
/// <param name="sid">服务名称</param>
/// <param name="user">用户</param>
/// <param name="pwd">密码</param>
/// <returns>OleDbConnection</returns>
private static OracleConnection ConnForOracle(string ip, string port, string sid, string user, string pwd)
{
string connStr;
connStr = "Data Source=(DESCRIPTION = (ADDRESS_LIST= (ADDRESS = (PROTOCOL = TCP)(HOST = " + ip + ")(PORT = " + port + "))) (CONNECT_DATA = (SERVICE_NAME = " + sid + ")));User ID=" + user + ";Password=" + pwd + ";";
Connection = new OracleConnection(connStr);
return Connection;
} /// <summary>

public static bool OpenConnection(string ip, string port, string sid, string user, string pwd)
{
ConnForOracle(ip, port, sid, user, pwd);
try
{
//不为空 并且 是关闭或者断了的情况下，才连接
if (Connection != null && (Connection.State == System.Data.ConnectionState.Closed || Connection.State == System.Data.ConnectionState.Broken))
{
Connection.Open();
ReturnOwner = Select("SELECT OWNER, TABLE_NAME FROM ALL_TAB_COMMENTS ORDER BY OWNER, TABLE_NAME");
}
MessageBox.Show(Connection.State.ToString());
return true;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString());
return false;
}
}
/// <summary>
/// 关闭
/// </summary>
public static void CloseConnection()
{
//不为空 并且 是打开状态下才关闭
if (Connection != null && Connection.State == System.Data.ConnectionState.Open)
{
Connection.Close();
}
} /// <summary>
/// 查询

/// <param name="sql">SQL语句</param>
/// <returns></returns>
private static DataTable Select(string sql)
{
OracleCommand cmd = new OracleCommand(sql, Connection);
OracleDataAdapter oda = new OracleDataAdapter(cmd);
DataTable dt = new DataTable();
oda.Fill(dt);
cmd.Dispose();
return dt;
} /// <summary>

public static void GetTableName(string owner)
{

}
/// <summary>

/// <param name="owner">拥有者</param>
/// <param name="name">表名</param>
public static void GetTableContent(string owner, string name)
{
ReturnTableContent = Select("SELECT COLUMN_NAME, DATA_TYPE, NULLABLE, DATA_LENGTH,(SELECT COMMENTS FROM ALL_COL_COMMENTS WHERE TABLE_NAME = '" + name + "' AND OWNER = '" + owner + "' AND COLUMN_NAME = a.COLUMN_NAME)COMMENTS FROM ALL_TAB_COLUMNS a WHERE TABLE_NAME = '" + name + "' AND OWNER = '" + owner + "' ORDER BY NULLABLE, COLUMN_NAME ");
}
#region 字段
/// <summary>

{

{

} set
{

#endregion
}

3、为了方便显示，要写一个Oracle的实体类，就是DataGrid显示的内容
public class TableVo : ObjectNotifyPropertyChanged
{
private string schema;//图表
private string name;//名称
private string comments;//注解
private string type;//类型
private string nullable;//是否可空
private string dataLength;//字段长度 public string Schema
{
get
{
return schema;
} set
{
schema = value;
RaisePropertyChanged("Schema");
}
} public string Name
{
get
{
return name;
} set
{
name = value;
RaisePropertyChanged("Name");
}
} public string Comments
{
get
{
return comments;
} set
{
comments = value;
RaisePropertyChanged("Comments");
}
} public string Type
{
get
{
return type;
} set
{
type = value;
RaisePropertyChanged("Type");
}
} public string Nullable
{
get
{
return nullable;
} set
{
nullable = value;
RaisePropertyChanged("Nullable");
}
} public string DataLength
{
get
{
return dataLength;
} set
{
dataLength = value;
RaisePropertyChanged("DataLength");
}
}
}
TableVo
4、由于小工具的左侧是一个TreeView，因此有一个TreeView实体，更便于管理和修改，而且此实体中一定要有父节点和子节点，已方便区分，和后期开发
public class PropertyNodeItem:ObjectNotifyPropertyChanged
{
private string icon;
private string parentName;
private string childrenName;
private bool isExpanded;
private List<PropertyNodeItem> children; public string Icon
{
get
{
return icon;
} set
{
icon = value;
RaisePropertyChanged("Icon");
}
} public string ParentName
{
get
{
return parentName;
} set
{
parentName = value;
RaisePropertyChanged("ParentName");
}
} public string ChildrenName
{
get
{
return childrenName;
} set
{
childrenName = value;
RaisePropertyChanged("ChildrenName");
}
} public bool IsExpanded
{
get
{
return isExpanded;
} set
{
isExpanded = value;
RaisePropertyChanged("IsExpanded");
}
} public List<PropertyNodeItem> Children
{
get
{
return children;
} set
{
children = value;
RaisePropertyChanged("Children");
}
} public PropertyNodeItem()
{
Children = new List<PropertyNodeItem>();
}
}
PropertyNodeItem
5、创建CS文件，需要同时创建两个，一个带有通知机制，一个不带有通知机制，创建方法无外乎就是拼接String，然后写入文件，很简单，就是在写的过程中，注意一下格式和转义字符
public class CreateVo
{
//不含通知机制
private static string pathVo1 = @"Dis/VoWithoutNotify";
//包含通知机制
private static string pathVo2 = @"Dis/VoWithNotify"; /// <summary>
/// 判断是否存在文件夹，不存在则创建
/// </summary>
/// <returns></returns>
public static bool CreateDirectory()
{
if (!Directory.Exists(pathVo1))
{
Directory.CreateDirectory(pathVo1);
}
if (!Directory.Exists(pathVo2))
{
Directory.CreateDirectory(pathVo2);
} if (Directory.Exists(pathVo1) && Directory.Exists(pathVo2))
return true;
else
return false;
} /// <summary>
/// 生成不含通知机制的VO
/// </summary>
/// <param name="NameSpace">命名空间</param>
/// <param name="name">文件名</param>
/// <param name="listName">列表</param>
public static void CreateVoNoINotifyPropertyChanged(string NameSpace,string name,List<TableVo> listName)
{
FileStream fs = new FileStream(pathVo1 + "/" + name + ".cs", FileMode.Create);
StreamWriter sw = new StreamWriter(fs);
sw.Write(CreateCSNoINotifyPropertyChanged(NameSpace,name,listName));
sw.Flush();
sw.Close();
fs.Close();
}
/// <summary>
/// 生成包含通知机制的VO
/// </summary>
/// <param name="NameSpace">命名空间</param>
/// <param name="name">文件名</param>
/// <param name="listName">列表</param>
public static void CreateVoWithINotifyPropertyChanged(string NameSpace, string name, List<TableVo> listName)
{
FileStream fs = new FileStream(pathVo2 + "/" + name + ".cs", FileMode.Create);
StreamWriter sw = new StreamWriter(fs);
sw.Write(CreateCSWithINotifyPropertyChanged(NameSpace, name, listName));
sw.Flush();
sw.Close();
fs.Close();
}
/// <summary>

6、最后就是需要VM和XAML两个文件来将这些类文件组合到一起，写具体的逻辑关系了
给TreeView写一个SelectedItemChanged事件，来保证每次选中TreeView时能够获取到当前的选中项，刚开始想写TreeView的SelectedItem属性的，可是怎么也写不出来，后来发现因为这个属性是只读的，所以只能写SelectedItemChanged事件了。

注意事项：
在最开始的连接Oracle中，我用的是OleDbConnection，连接语句里用到了“Provider=OraOLEDB.Oracle.1;”，也就是用到了Oracle的驱动，这个在没有注册的时候会弹出
未在本地计算机注册“OraOLEDB.Oracle.1”，在我的机器上注册成功，好使了，但是在我同事的机器上，注册成功了，依然会有这个提示，不能成功连接数据库，因此，最终，选用了Oracle.ManagedDataAccess.DLL文件，它是oracle官方的托管驱动，有6M多，但是有了这个文件以后，直接使用OracleConnection就不会爆出连接问题了。
总结：做这个小工具没有什么难度，用到的方法有Linq、Oracle的Select语句、StreamWriter写入文件等，但是对于我们的开发还是蛮实用的，希望看到的朋友可以根据你们的项目需求，做出其他版本的小工具，大家一起探讨、成长。
