动软 生成 linq相关DAO

第一步:新建自定义模板

<#@ template language="c#" HostSpecific="True" #>
<#@ output extension= ".cs" #>
<#
TableHost host = (TableHost)(Host);
host.Fieldlist.Sort(CodeCommon.CompareByintOrder);
string identityKey=host.IdentityKey.ColumnName ;
string ClassName =host.TableName;
string ClassNames =host.TableName+"s";
#>
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Data.SqlClient;
namespace DAL
{
public class <#= ClassName #>_DAO
{ public static string Insert(<#= ClassName #> objEntity)
{
try
{
HISDataContext db = DatabaseHelper.GetDB();
db.<#= ClassNames #>.InsertOnSubmit(objEntity);
db.SubmitChanges();
}
catch (System.Exception ex)
{
return ex.Message;
}
return string.Empty;
} public static string Update(<#= ClassName #> model)
{
try
{
HISDataContext db = DatabaseHelper.GetDB();
<#= ClassName #> oldEntity = db.<#= ClassNames #>.First(c => c.<#= identityKey #> == model.<#= identityKey #>);
DatabaseHelper.Assign<<#= ClassName #>>(model, oldEntity);
db.SubmitChanges();
return "";
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
} public static string DeleteById(int ID)
{
try
{
HISDataContext db = DatabaseHelper.GetDB();
var rs = db.<#= ClassNames #>.Where(c => c.<#= identityKey #> == ID);
if (rs.Count() > )
{
<#= ClassName #> objKey = rs.First<<#= ClassName #>>();
db.<#= ClassNames #>.DeleteOnSubmit(objKey);
db.SubmitChanges();
}
}
catch (System.Exception ex)
{
return ex.Message;
}
return "";
} public static <#= ClassName #> SelectByID(long ID)
{
try
{
HISDataContext db = DatabaseHelper.GetDB();
var rs = (from a in db.<#= ClassNames #>
where a.<#= identityKey #> == ID
select a).ToList<<#= ClassName #>>();
if (rs.Count() > )
return rs.First<<#= ClassName #>>();
else
return null;
}
catch (System.Exception ex)
{
throw new Exception(ex.Message);
}
} public static List<<#= ClassName #>> SelectAll()
{
try
{
HISDataContext db = DatabaseHelper.GetDB();
var list = (from n in db.<#= ClassNames #>
orderby n.<#= identityKey #> descending
select n).ToList<<#= ClassName #>>();
if (list.Count > )
{
return list;
}
else
{
return null;
} }
catch (System.Exception ex)
{
throw new Exception(ex.Message);
}
} } }

如果你的dao名称就是表名的话 那忽略第二步

第二步:批量修改生成文件名

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO; namespace Tools
{
/*
* kook 动软生成dal 用这个批量修改名称 给表名后边加上_dao
* 例如:t_user.cs-->t_user_DAO.cs
*/
class EditFileName
{
static void Main(string[] args)
{
Console.WriteLine("本程序修改动软生成的dao");
RenameFile(@"D:\CodematicDemo\linq", "_DAO");
Console.WriteLine("操作已完成");
Console.ReadKey();
}
public static void RenameFile(string ParentDir, string stringFront)
{
string[] files = Directory.GetFiles(ParentDir, "*.cs", SearchOption.TopDirectoryOnly);
foreach (string file in files)
{
string filename = Path.GetFileName(file);
string pathname = Path.GetDirectoryName(file);
filename = filename.Substring(,filename.Length-) + "_DAO"+".cs";
FileInfo fi = new FileInfo(file);
fi.MoveTo(Path.Combine(pathname, filename));
}
string[] dirs = Directory.GetDirectories(ParentDir);
foreach (string dir in dirs)
{
RenameFile(dir, stringFront);
}
}
}
}
