I am creating installation package for our component. One of the Pr-requisites is oracle client with minimum version 8i should be installed in the target machine. How can i do this?

我提及后下

的什么是确定哪个版本的最好方法Oracle客户端我跑？

有了这个我写了下面的动作。我想请与用tnsping实用

by having this i wrote the below action. I tried to check with tnsping utility.

string result = string.Empty;
                System.Diagnostics.ProcessStartInfo proces = new System.Diagnostics.ProcessStartInfo("tnsping.exe");
                proces.RedirectStandardOutput = true;
                proces.CreateNoWindow = true;
                proces.UseShellExecute = false;
                System.Diagnostics.Process bufor;
                bufor = System.Diagnostics.Process.Start(proces);
                System.IO.StreamReader Output = bufor.StandardOutput;
                bufor.WaitForExit(2000);
                if (bufor.HasExited)
                {
                    result = Output.ReadToEnd();
                    result = result.ToLower();
                    if (result.Contains("64-bit"))
                    {
                        is64BitOracleClient = true;
                    }

                    int verINT = result.IndexOf("version", 0, result.Length);
                    if (verINT != null)
                    {
                        version = result.Substring(verINT + "version".Length + 1, 8);
                        Version installedVersion = new Version(version);
                        Version expectedVersion = new Version("8.1.7.0");
                        if (installedVersion >= expectedVersion)
                        {
                            isVersionMatched = true;
                        }
                    }
                }

我在这里执行工具TNSPING 。如果我收到的例外在

here i am executing tool tnsping. if i receive exception at

bufor = System.Diagnostics.Process.Start(proces);

我的结论是，Oracle客户端没有安装。

I concluded that Oracle Client is not installed.

如果这个工具可用，我得到下面的结果很

If this tool is available, i am getting below result

TNS Ping Utility for 64-bit Windows: Version 11.2.0.1.0 - Production on 16-AUG-2
012 06:27:58

从这个结果，我解析版本和验证相同。

from this result, I am parsing version and validating the same.

这是正确的做法？任何其他更好的办法是在那里？

Is this right approach? Any other better approach is there?
