　　asp.net|object|oracle|数据|数据库

1、先在WEB应用程序项目中添加引用：Interop.OracleInProcServer

2、Web.config的配置：

……

3、Global.asax中创建OracleSession对象，代码如下：

using System;
using System.Collections;
using System.ComponentModel;
using System.Web;
using System.Web.SessionState;

namespace SparePart
{
/// <summary>
/// Global 的摘要说明。
/// </summary>
public class Global : System.Web.HttpApplication
{
  /// <summary>
  /// 必需的设计器变量。
  /// </summary>
  private System.ComponentModel.IContainer components = null;
  static public OracleInProcServer._OraSessionClassClass OraSession;
  static public OracleInProcServer.OraDatabase OraDataBase;

  public Global()
  {
   InitializeComponent();
  }

  protected void Application_Start(Object sender, EventArgs e)
  {
   OraSession=new OracleInProcServer._OraSessionClassClass();
   OraSession.CreateDatabasePool(Convert.ToInt32(System.Configuration.ConfigurationSettings.AppSettings["Min Pool Size"]),Convert.ToInt32(System.Configuration.ConfigurationSettings.AppSettings["Max Pool Size"]),30,System.Configuration.ConfigurationSettings.AppSettings["Data Source"],System.Configuration.ConfigurationSettings.AppSettings["User ID"]+"/"+System.Configuration.ConfigurationSettings.AppSettings["Password"],0);

  }

  protected void Session_Start(Object sender, EventArgs e)
  {
   Session["OraDatabase"] =(OracleInProcServer.OraDatabase)OraSession.get_GetDatabaseFromPool(30);
  }

protected void Application_BeginRequest(Object sender, EventArgs e)
{

}

protected void Application_EndRequest(Object sender, EventArgs e)
{

}

protected void Application_AuthenticateRequest(Object sender, EventArgs e)
{

}

  protected void Application_Error(Object sender, EventArgs e)
  {

  }

  protected void Session_End(Object sender, EventArgs e)
  {
   OracleInProcServer.OraDatabase OraDatabase=(OracleInProcServer.OraDatabase)Session["OraDatabase"];
   OraDatabase.Close();

Session["OraDatabase"]=null;
}

  protected void Application_End(Object sender, EventArgs e)
  {

  }

  #region Web 窗体设计器生成的代码
  /// <summary>
  /// 设计器支持所需的方法 - 不要使用代码编辑器修改
  /// 此方法的内容。
  /// </summary>
  private void InitializeComponent()
  {
   this.components = new System.ComponentModel.Container();
  }
  #endregion
}
}

4、简单应用（default.aspx）：

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace SparePart
{
/// <summary>
/// WebForm1 的摘要说明。
/// </summary>
public class Default : System.Web.UI.Page
{
  private void Page_Load(object sender, System.EventArgs e)
  {
   // 在此处放置用户代码以初始化页面
   OracleInProcServer.OraDatabase OraDatabase=(OracleInProcServer.OraDatabase)Session["OraDatabase"];
   OracleInProcServer.OraDynaset OraRs;
   OracleInProcServer.OraFields OraFs;
   OracleInProcServer.OraField OraF;

   OraRs=(OracleInProcServer.OraDynaset)OraDatabase.get_CreateDynaset("select * from test",0);
   OraDatabase.ExecuteSQL("insert into test(username,password) values ('你们','密码')");
   Response.Write("<table border=1>");
   while (!OraRs.EOF)
      {
     OraFs=(OracleInProcServer.OraFields)OraRs.Fields;
     OraF=(OracleInProcServer.OraField)OraFs["username"];

Response.Write("<tr><td>姓名</td><td>");
Response.Write(OraF.Value);

Response.Write("</td><td>密码</td><td>");
OraF=(OracleInProcServer.OraField)OraFs["password"];

     Response.Write(OraF.Value);
     Response.Write("</td></tr>");
     OraRs.MoveNext();
      }
   Response.Write("</table>");
   OraRs.Close();

  }

  #region Web 窗体设计器生成的代码
  override protected void OnInit(EventArgs e)
  {
   //
   // CODEGEN: 该调用是 ASP.NET Web 窗体设计器所必需的。
   //
   InitializeComponent();
   base.OnInit(e);
  }

  /// <summary>
  /// 设计器支持所需的方法 - 不要使用代码编辑器修改
  /// 此方法的内容。
  /// </summary>
  private void InitializeComponent()
  {
   this.Load += new System.EventHandler(this.Page_Load);

}
#endregion
}
}
