??????? Sometimes you have to write a code from the data layer when you do something about the database, this is not too tired and does not match the essence of programming work, then do a for SQL Automatically complete the database layer of the database and C # language.
?????? Overview:
?????? The target of the tool:
1. ?????? Automatically generate basic stored procedures based on your design, Idd, Update, Delete, SELECT
2. ?????? Automatically generate C # code classes based on your database and stored procedure.
3. ?????? Automatically add the code class to your project.
???????? Target service object
1. Slowly add the programmer for the development platform and the program for the development of the language (other languages such as VB.NET, J #, etc.:))
?????
1. It is best to exist in the form of .NET's external procedure so that you open .NET is not very convenient to the toolbar.
?????? the value of the tool
1. Imagine this thing, your program about the database is not very fast, it is also very cool?
???????????????????????????????????????????????????????????????????????????????????
1. Is there any time?
2. Inspiring enough? (In fact, it is a little annoying me to do it. When I do it, I have a great help for me to reduce the workload of others and others (ie: I am annoying now. ) :))
3. Programming the .NET platform, in fact, it is mainly used to envdet namespaces, using regular expressions. Operate the system table of the SQL database.
Now I put a small part (still a little more, only sticky some) code stick this (in fact I have uploaded in the CSDN software version, but I can't release it, I don't know why) Interested, JINLEI_REN @ Hotmail .com qq: 24936285?

Also bad about the class of the external program, the class of regular expressions, not sticking, too much trouble, and confusion, or contact me, in fact, my purpose is to enhance someone to expand it, for example, not only support The language of the .NET C #?, also supports VB J #? What, and more likely, it is best to make a code that can generate a logical relationship in the class according to the primary key in the database. Finally forming a only need Design the database. Other things are automatically done.
