Microsoft.Practices.EnterpriseLibrary连接Oracle
1、引用dll
安装后在安装目录下找到以下dll：
先复制到项目目录先，并引用。
2、配置连接数据库的配置文件
你可以利用程序配置，也可以生成一个空白文档手动配置。如图，
第一步，运行安装目录下EntLibConfig.exe：
第二步，选择blocks菜单配置数据库连接：
第三步，配置连接数据库，也可以直接File-save as保存为一个空config文件手动配置：
这里是保存一个空的配置进行手动配置，空配置如下：
[html]
<configuration>
<configSections>
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
</configSections>
<dataConfiguration defaultDatabase="Connection String" />
<connectionStrings>
<add name="Connection String" connectionString="Database=Database;Server=(local)\SQLEXPRESS;Integrated Security=SSPI"
providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>
<configuration>
<configSections>
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
</configSections>
<dataConfiguration defaultDatabase="Connection String" />
<connectionStrings>
<add name="Connection String" connectionString="Database=Database;Server=(local)\SQLEXPRESS;Integrated Security=SSPI"
providerName="System.Data.SqlClient" />
</connectionStrings>
</configuration>手动配置，这里以oracle为例进行配置。如下：
[html]
<?xml version="1.0"?>
<configuration>
<configSections>
<!--添加配置企业库(1)-->
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings,
Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
</configSections>
<!--添加配置企业库(2)-->
<dataConfiguration defaultDatabase="Oracle.ConnectionString"/>
<!--添加配置企业库(3)-->
<connectionStrings>
<add name="Oracle.ConnectionString" connectionString="Data Source=数据库名;Persist Security Info=True;
User ID=用户名;Password=密码;Unicode=True" providerName="System.Data.OracleClient"/>
</connectionStrings>
</configuration>
<?xml version="1.0"?>
<configuration>
<configSections>
<!--添加配置企业库(1)-->
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings,
Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
</configSections>
<!--添加配置企业库(2)-->
<dataConfiguration defaultDatabase="Oracle.ConnectionString"/>
<!--添加配置企业库(3)-->
<connectionStrings>
<add name="Oracle.ConnectionString" connectionString="Data Source=数据库名;Persist Security Info=True;
User ID=用户名;Password=密码;Unicode=True" providerName="System.Data.OracleClient"/>
</connectionStrings>
</configuration>
好了，这些准备工作完成了，下面看代码中如何使用吧。这里测试读取，当然其他的操作都一样。
[csharp]
public class OracleSqlHelper
{
private static Database db = null;
public static DataSet GetDataTable( string commandText)
{
try
{
DataSet resultDataSet = null;
db = DatabaseFactory.CreateDatabase();//建立数据库连接
resultDataSet =db.ExecuteDataSet(CommandType.Text, commandText);//执行
return resultDataSet;
}
catch (Exception ex)
{
return null;
throw ex;
}
}
}
public class OracleDataProvider
{
public static DataTable TestReadTable(string id)
{
DataTable dataTable = null;
try
{
string commandText = "select tu.name from tabUser tu";
DataSet resultTable = OracleSqlHelper.GetDataTable(commandText);
int table = resultTable != null ? resultTable.Tables.Count : 0;
补充：软件开发 , C# ,
