问题描述：

我已经安装了Oracle客户端10g版本我的电脑上（注册ORACLE_BASE-D：\\ ORACLE \\产品\\ 10.2.0）。
我已经添加下面引用。
System.Data.OracleClient的。

我收到上述的错误。
下面是code片段。

I am getting above mentioned error. Below is the Code Snippet .

public static OracleConnection getConnection() 
    {

        try 
        {
            dataSource = new SqlDataSource();
            dataSource.ConnectionString = System.Configuration.ConfigurationManager.AppSettings.Get("conn");
            OracleConnection connection = new OracleConnection();
            if (dataSource == null) 
            {
                // Error during initialization of InitialContext or Datasource
                throw new Exception("###### Fatal Exception ###### - DataSource is not initialized.Pls check the stdout/logs.");
            } 
            else
            {
                connection.ConnectionString = dataSource.ConnectionString;
                connection.Open();
            }

Please let me know what are the areas of Concern and where Iam missing.I am new for the combination of Oracle and Asp.Net.

它看起来像您使用Microsoft Oracle客户端。我建议你使用ODP.net驱动程序，因为它是更可靠。（我相信微软客户端是德$ P $也pcated？）

It looks like you are using the Microsoft oracle client. I suggest that you use the ODP.net driver as it is much more reliable. (I believe the Microsoft client is being deprecated also?)

安装驱动程序ODP.net，在你的项目中添加对Oracle.DataAccess的引用，你是好去！例如code（从我的$p$pvious帖子）：

Install the ODP.net driver, add a reference to Oracle.DataAccess in your project, and you are good to go! Example code (from my previous post):

using System;
using System.Data;
using Oracle.DataAccess.Client;

static class Program
{
    [STAThread]
    static void Main()
    {
        TestOracle();
    }

    private static void TestOracle()
    {
        string connString = 
            "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)" + 
            "(HOST=servername)(PORT=‌1521)))" +
            "(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=servicename)));"+ 
            "User Id=username;Password=********;";
        using (OracleConnection conn = new OracleConnection(connString))
        {
            string sqlSelect = "SELECT * FROM TEST_TABLE";
            using (OracleDataAdapter da = new OracleDataAdapter(sqlSelect, conn))
            {
                var table = new DataTable();
                da.Fill(table);

                if (table.Rows.Count > 1) 
                    Console.WriteLine("Successfully read oracle.");
            }
        }
    }
}

编辑：我也遇到了需要Oracle客户端软件版本8.1.7或更高版本错误之前。我是通过安装Oracle客户端到我的电脑引起的。您可以尝试从计算机中卸载Oracle客户端（讽刺）如果您在使用Microsoft驱动程序设置。

I also encountered the "requires Oracle client software version 8.1.7 or greater" error before. I was caused by installing the Oracle Client onto my computer. You may try uninstalling the Oracle Client (ironically) from your computer if you are set on using the Microsoft driver.
