但是一般服务器都是64位的,安装的也是64位的Oracle客户端,如果要部署使用Oracle.DataAccess连接Oracle的应用程序时,可能会遇到版本上的问题。...另一个版本问题是Oracle.DataAccess的版本号问题,我的本机就是32位的XP,安装了Oracle11gR2客户端后,在安装目录下的ODP.NET\bin\2.x目录中可以找到Oracle.DataAccess.dll...但是在64位下的Oracle.DataAccess.dll却不一样,安装后的版本是2.112.1.0,如图是Windows2008X64上的Oracle.DataAccess.dll。...或者是 Could not load file or assembly 'Oracle.DataAccess, Version=2.112.1.2, Culture=neutral, PublicKeyToken...显然,这里系统找的是2.112.1.2版本的Oracle.DataAccess,而服务器上只有2.112.1.0版本的,所以才报错,解决办法就是在web.config中修改,在configSections

DataAccess 是接口的实现类,通过下面的几个类进行隐藏,不直接暴露给外界方法。一些接口的实现如下所示。.../// /// /// private readonly IDataAccess _dataAccess; /// /// ctor /...// /// public DataAccessProxy(IDataAccess dataAccess) {..._dataAccess = dataAccess ??...throw new ArgumentNullException("dataAccess is null"); } /// /// 执行SQL语句或存储过程,返回IList对象
Console.WriteLine("在Access中根据ID得到User表的一条记录"); return null; } } DataAccess...类 class DataAccess { private static readonly string AssemblyName = "抽象工厂"; //直接写字符串获得...Sqlserver"/> 客户端代码 User user = new User(); IUser iu = DataAccess.CreateUser...iu.GetUser(1); Department dept = new Department(); IDepartment id = DataAccess.CreateDepartment
下面是一个示例代码,演示了如何使用 IDataAccess 接口实现一个数据操作类:public class DataOperator{ private readonly IDataAccess _dataAccess...; public DataOperator(IDataAccess dataAccess) { _dataAccess = dataAccess; } public...void Query() { _dataAccess.Query(); } // 其他查询方法 public void Update() {..._dataAccess.Update(); } // 其他更新方法 public void Delete() { _dataAccess.Delete();

正常情况下这样安装和配置完成就没问题了 遇到的问题和解决方法 比如你已经安装了其它版本的Oracle 客户端比如12C,或其他版本 那么就会出现以下的 以上问题的原因是Oracle Adapter引用了Oracle.DataAccess.dll...machine.config <add name="Oracle Data Provider for .NET" invariant="Oracle.<em>DataAccess</em>.Client..." description="Oracle Data Provider for .NET" type="Oracle.<em>DataAccess</em>.Client.OracleClientFactory, Oracle.<em>DataAccess</em>

在C#项目中添加Oracle.DataAccess的引用,这是Oracle为.Net开发的类库,可以从官网下载。...添加引用后,再添加命名空间: using Oracle.DataAccess.Types; using Oracle.DataAccess.Client; 然后再创建Student对应的类: 代码public...IOracleCustomType { #region IOracleCustomType Members public void FromCustomObject(Oracle.DataAccess.Client.OracleConnection...OracleUdt.SetValue(con, pUdt, "STUDESCRIPTION", Description); } public void ToCustomObject(Oracle.DataAccess.Client.OracleConnection
[OperationContract] TbGuestBook GetDataID(string ID); } } 然后,我们来实现这个契约,把如下代码保存为DataAccess.cs...namespace Service { [ServiceBehavior(IncludeExceptionDetailInFaults = true)] public class DataAccess...: IDataAccess { GuestBook ctx; public DataAccess() { XmlMappingSource...net.tcp://localhost:880/DataAccessService"); using (ServiceHost sh = new ServiceHost(typeof(DataAccess
添加Oracle.DataAccess.dll 引用。 3. 添加Oracle.DataAccess 命名空间。 4.
通过反编译ODP.Net里面的Oracle.DataAccess.dll发现,它会先找注册表,然后是配置文件,从中找一些设置,第一个就是DllPath,我估计这个就是OCI的路径。...> OraOps11w.dll=>oci.dll,前面两者的版本必须100%匹配(OraOps11w.dll...里面通过硬编码写死了的)(也许这就是Oracle官方把OraOps11w.dll跟Oracle.DataAccess.dll放在一起的原因)。

的引用,该文件位于%Oracle_Home%\11.2.0\odp.net\bin\4下 示例代码如下: using System; using Oracle.DataAccess.Client; using...PERSIST SECURITY INFO=True;USER ID=SCOTT;Password=tiger"; string ProviderName = "Oracle.DataAccess.Client...PERSIST SECURITY INFO=True;USER ID=SCOTT;Password=tiger"; string ProviderName = "Oracle.DataAccess.Client...", i); } } sw.Stop(); Console.WriteLine("Oracle.DataAccess.Client...}毫秒", max, sw.ElapsedMilliseconds); Console.ReadLine(); } } } 运行结果: Oracle.DataAccess.Client
比如那个PL Dev,只需要拷贝OCI,然后选项里面指定oci目录即可 3,如果你怀疑上述两点,你可以不用看本文了 4,OCI.dll的版本和Oracle.DataAccess.dll要求的版本必须一致...,不一致就自己凑,找到一致的 5,.Net程序调用Oracle.DataAccess.dll,而Oracle.DataAccess.dll会找OCI.dll,顺序是:当前目录、配置文件指定目录、环境变量
