我想以编程方式枚举服务器上的SQL Server 2005命名实例。我知道我应该能够相当容易地做到这一点，但我不能为我的生活弄清楚如何。在此先感谢您的帮助！

这是我刚才写的内容......这不完全相同，但它可能会让你知道如何做到这一点。这里我列举并检查sql server的快速版本，但你应该能够改变它...你需要去注册表找到sql server 2005的SKUNAME和SKULEVEL。

public static bool IsSqlExpressPresent(string strInstance, Utility.Log log)
{
    const string edition = "Express Edition";
    string instance = "MSSQL$" + strInstance.ToUpper();
    const int spLevel = 1;

    bool fCheckEdition = false;
    bool fCheckSpLevel = false;

    try
    {
        // Run a WQL query to return information about SKUNAME and SPLEVEL about installed instances
        // of the SQL Engine.
        ManagementObjectSearcher getSqlExpress =
                new ManagementObjectSearcher("root\\Microsoft\\SqlServer\\ComputerManagement",
                "select * from SqlServiceAdvancedProperty where SQLServiceType = 1 and ServiceName = '"
                + instance + "' and (PropertyName = 'SKUNAME' or PropertyName = 'SPLEVEL')");

        // If nothing is returned, SQL Express isn't installed.
        if (getSqlExpress.Get().Count == 0)
        {
            return false;
        }

        // If something is returned, verify it is the correct edition and SP level.
        foreach (ManagementObject sqlEngine in getSqlExpress.Get())
        {
            if (sqlEngine["ServiceName"].ToString().Equals(instance))
            {
                switch (sqlEngine["PropertyName"].ToString())
                {
                    case "SKUNAME":
                        // Check if this is Express Edition or Express Edition with Advanced Services
                        fCheckEdition = sqlEngine["PropertyStrValue"].ToString().Contains(edition);
                        break;

                    case "SPLEVEL":
                        // Check if the instance matches the specified level
                        fCheckSpLevel = int.Parse(sqlEngine["PropertyNumValue"].ToString()) >= spLevel;
                        //fCheckSpLevel = sqlEngine["PropertyNumValue"].ToString().Contains(spLevel);
                        break;
                }
            }
        }

        if (fCheckEdition & fCheckSpLevel)
        {
            return true;
        }
        return false;
    }
    catch (ManagementException e)
    {
        if (log != null)
        {
            log.Write(
               Utility.LogState.Error,
               "Database",
               "Could not find OfficeClip instance of SqlExpress: " + e.ErrorCode + ", " + e.Message
               );
        }
        return false;
    }
}
