Description: ADO.NET在Java中的使用
ADO.NET最大的特性在于对断开数据库连接方式的全方位支持,它包括DataSet、DataTable、DataRow等对象,构建了一个内存中的数据库,通过DataAdapter把数据填充到DataTable或者DataSet中,随后通过DataTable和DataSet对象提供的一些方法对存储在内存中的数据进行操作-ADO.NET in Java use ADO.NET features the largest database connection is to disconnect all-round way to support, which includes the DataSet, DataTable, DataRow object, etc., build up a database in memory, through the DataAdapter to fill the data DataTable or DataSet, the DataTable and DataSet subsequently adopted a number of clients, methods of storing data in memory to operate Platform: |

Description: 曾在.Net平台下有过大约3年的Web程序开发实践,甚是喜欢其中ADO.Net技术。ADO.NET最大的特性在于对断开数据库连接方式的全方位支持,它包括DataSet、DataTable、DataRow等对象,构建了一个内存中的数据库,通过DataAdapter把数据填充到DataTable或者DataSet中,随后通过DataTable和DataSet对象提供的一些方法对存储在内存中的数据进行操作。ADO.NET还能够和ASP.NET和Windows Forms的控件进行数据邦定,使得编写程序很简单,在实际应用中开发效率非常之高-In. Net platform has been about 3 years of Web application development practices, very likes of which ADO.Net technology. ADO.NET disconnected the biggest feature is the right way all-round support for the database connection, which includes the DataSet, DataTable, DataRow and other objects, to build an in-memory database, the data through the DataAdapter fill DataTable or a DataSet, then through the DataTable and the DataSet object provides a number of methods of data stored in memory to operate. ADO.NET is also able to ASP.NET controls and Windows Forms data bonding, making the preparation process is very simple, in practical application development efficiency is very high Platform: |

Description: 本书是使用Microsoft Visual Studio .NET和ADO.NET编写高可伸缩性、可用Web数据库应用程序的开发人员必备指南。介绍了如何使用ADO.NET在企业级的Web应用程序中访问、排序和处理数据。通过书中丰富的实例和工具,读者能够了解编写、测试与调试数据库应用程序代码的方法。本书还介绍了ADO.NET对象模型,用于Web扩展性的XML特性,与SQL Server 2000的集成。 全书共分5大部分。第I部分提供了ADO.NET对象模型的概要叙述,并且提供了【数据窗体向导】的指导内容。第Ⅱ部分介绍了如何使用.NET数据提供程序中的不同对象——Connection、Command、DataReader和DataAdapter对象。第Ⅲ部分包含了对ADO.NET对象模型中的脱机对象的讨论——DataSet、DataTable、DataColumn、DataRow、DataRelation和DataView对象。这一部分还介绍了使用DataAdapter向数据库提交更改的基本和高级场景,还讨论了ADO.NET的XML特性。第Ⅳ部分介绍了使用ADO.NET建立有效率的Windows应用程序和Web应用程序的技术。第V部分是附录。 -This book is the use of Microsoft Visual Studio. NET and ADO.NET to prepare highly scalable, available Web database application developers an essential guide. Describes how to use ADO.NET in an enterprise-class Web applications to access, sorting and processing data. Through the book a wealth of examples and tools, readers can understand the preparation, testing and debugging database application code approach. The book also describes the ADO.NET object model for Web extensibility of XML features, and SQL Server 2000 integration. The book is divided into five majority. Part I, provide a narrative summary of ADO.NET object model and provides】 【Data Form Wizard to guide the content. Chapter Ⅱ section describes how to use.

Description: 数据库访问操作
数据库操作类: 支持 SQLServer mysql sqlite Sybase Oracle等DB 数据库操作类
包括执行SQL或者存储过程,返回DataSet、DataTable等功能
完全支持存储过程和参数调用
javascriptClassLibrary 包括一些JavaScript 类封装
StringValid:字符串校验类
说明:
代码全部都是用 C# 语言(除JavaScript部分)
基于.net 2.0平台,
纯IL语言
Asp.net 和Winform WPF都可以使用
类库还分X86 和ANY 两种平台,满足将来 64位操作系统需要!
怎么使用呢?
1、ConnectionStrings.com 查找到 所需要的数据连接 字符串
2、找连接所需要类
我差不多都给你准备好了
3、区分好X86 和ANY的库
对于32位数据库只能用X86,64位的话用Any
比如 Sql Server 就有32位和64位之分
假如 你都用 32位,就用X86
如果 你打算 32位系统用32位Sql Server ,64位系统用64位Sql Server
那么可以使用Any
另外要注意 有的数据库只有32位,截至软件发布 2009-11-6 Sql Server Express和Access 都只有32位
4、 使用Microsoft Visual Studio 或者其他工具引用你需要的库
像 Sybase sqlite 都有链接库
就必须都要拷贝过去-Database operations categories: support for SQLServer mysql sqlite Sybase Oracle database operations such as DB Category
Including the implementation of SQL or stored procedure and return DataSet, DataTable etc.
Fully support the call stored procedures and parameters
javascriptClassLibrary including some JavaScript class encapsulates
StringValid: String Validation Class
Description:
All the code with C# language (except for some JavaScript)
Based. Net 2.0 platform
The language of pure IL
Asp.net and Winform WPF can be used
ANY library also points X86 and two platforms to meet the needs of the future 64-bit operating system!
How to use it?
1, ConnectionStrings.com find the required data connection string
2, to connect the required class
I am almost ready to give you
3, the distinction between good and ANY X86 libraries
Database can only be used for 32-bit X86, 64-bit words with Any
Such as Sql Server have 32-bit and 64-bit divided

Description: 下面以Access数据库为例说明,用C#的DataSet类访问数据库的一些操作方法。操作涉及的主要C#类有:DataSet:对应数据库表的一个集合,实际上是数据库表在内存中的一个缓存DataTable:对应数据库表,是数据库表行的集合DataRow:对应数据库表行
OleDbConnection:建立数据库连接OleDbDataAdapter:由数据库生成DataSet,并负责DataSet与数据库的同步OleDbCommandBuilder:生成更新数据库所需的指令DataSet、DataTable、DataRow用于数据在缓存中的操作,这上面的操作只有更新到数据库中,修改结果才会被永久保存。OleDbConnection 是用OLEDB方法连接数据库所必需的。-The following Access database, for example, methods of operation to access the database with C# DataSet class. Operation involves the main C#
Class: DataSet: corresponds to a collection of database tables, is actually a database table in memory, a cache a DataTable:
The corresponding database table, database table rows collection of a DataRow: the corresponding database table row
The OleDbConnection: to establish a database connection the OleDbDataAdapter: generate a DataSet from the database, and is responsible for the DataSet
The OleDbCommandBuilder of database synchronization: generate the instructions required to update the database a DataSet, DataTable, a DataRow
For the operation of the data in the cache, the above operation only updates to the database, modify the results will be permanently saved.
OleDbConnection to connect to the database using the OLEDB method necessary. Platform: |

Description: C#读写Excel文件、不需要office支持,可读取Excel文件到DataSet、DataTable中,也可以将内存表写入到Excel文件。包含几个dll组件和一个cs代码文件,有详尽注释,我自己经常用。不过导出的性能不好,如果是上万行的数据导出到Excel会很慢。-C# to read and write Excel files, no office support, you can read Excel files to DataSet, DataTable, you can also write to the memory table to an Excel file. Dll contains several components and a cs code file, there are detailed notes, I often use. However, export performance is not good, if it is thousands of rows of data exported to Excel will be very slow. Platform: |
