如何在我的应用程序设置期间使用C#安装ODBC驱动程序？

Question

我正在使用c#.net创建一个应用程序.该应用程序依赖于PostgrSQL ODBC驱动程序,因此必须检查用户计算机上是否已安装该驱动程序.如果不是,则必须在我的应用程序自己的安装过程中安装ODBC驱动程序.还必须在设置期间配置DSN.

因此,我的问题是,有没有办法在安装过程中首先检查驱动程序,如果不存在,可以将设置设置为自动安装驱动程序并配置DSN吗？

我正在使用Microsoft Visual Studio 2010,但我无法看到如何在发布向导中包含其他设置.我也在努力在Google或stackoverflow上找到任何有用的信息.

我在本网站的第一部分问题上找到了一个很好的例子.

至于第二部分,"如何配置DSN",我找到了另一个代码片段,只需要一些调整.

    private const string ODBC_INI_REG_PATH = "SOFTWARE\\ODBC\\ODBC.INI\\";
    private const string ODBCINST_INI_REG_PATH = "SOFTWARE\\ODBC\\ODBCINST.INI\\";

    /// <summary>
    /// Creates a new System-DSN entry with the specified values. If the DSN exists, the values are updated.
    /// </summary>
    /// <param name="dsnName">Name of the DSN for use by client applications</param>
    /// <param name="description">Description of the DSN that appears in the ODBC control panel applet</param>
    /// <param name="server">Network name or IP address of database server</param>
    /// <param name="driverName">Name of the driver to use</param>
    /// <param name="trustedConnection">True to use NT authentication, false to require applications to supply username/password in the connection string</param>
    /// <param name="database">Name of the datbase to connect to</param>
    public static void CreateDSN2(string dsnName, string description, string server, string driverName, bool trustedConnection, string database, string user, string password, string port)
    {
        // Lookup driver path from driver name
        var driverKey = Registry.LocalMachine.CreateSubKey(ODBCINST_INI_REG_PATH + driverName);
        if (driverKey == null) throw new Exception(string.Format("ODBC Registry key for driver '{0}' does not exist", driverName));
        string driverPath = driverKey.GetValue("Driver").ToString();

        // Add value to odbc data sources
        var datasourcesKey = Registry.LocalMachine.CreateSubKey(ODBC_INI_REG_PATH + "ODBC Data Sources");
        if (datasourcesKey == null) throw new Exception("ODBC Registry key for datasources does not exist");
        datasourcesKey.SetValue(dsnName, driverName);

        // Create new key in odbc.ini with dsn name and add values
        var dsnKey = Registry.LocalMachine.CreateSubKey(ODBC_INI_REG_PATH + dsnName);
        //MessageBox.Show(dsnKey.ToString());
        if (dsnKey == null) throw new Exception("ODBC Registry key for DSN was not created");
        dsnKey.SetValue("Data Source", dsnName);
        dsnKey.SetValue("Database", database);
        dsnKey.SetValue("Description", description);
        dsnKey.SetValue("Driver", driverPath);
        dsnKey.SetValue("Server", server);
        dsnKey.SetValue("User name", user);
        dsnKey.SetValue("Password", password);
        dsnKey.SetValue("Port", port);
        dsnKey.SetValue("Trusted_Connection", trustedConnection ? "Yes" : "No");
    }
