I am just being picky and really wanted some of my code to look, feel, and be used a specific way but am not sure if its possible.

I have a class I created that can be used like this

Query("ServerName", "TSQL").Run()

sample:

 class Query
    {
        public string serverName { get; set; }
        public string tSQL { get; set; }
        public Query(string ServerName, string TSQL)
        {
            serverName = ServerName;
            tSQL = TSQL;
        }

        public void Run()
        {
            //DO STUFF
        }
    }

is it possible to create a class and sub classes so that I use it like this

Query.Server("ServerName").TSQL("TSQL").Run()

Yes, what you're referring to is method chaining. You would add these methods to your class, and the return for each method would be the class itself. 

class Query
{
    public string serverName { get; set; }
    public string tSQL { get; set; }
    public Query(string ServerName, string TSQL)
    {
        serverName = ServerName;
        tSQL = TSQL;
    }

    public void Run()
    {
        //DO STUFF
    }  

    public Query Server(string svrName)
    {
        serverName = svrName;
        return this;
    }

    public Query TSql(string tsql)
    {
        tSQL = tsql;
        return this;
    }
}

As long as each method in the chain returns the updated object in question rather than void or some other class it will function just fine. Given the simplistic nature of this usage, I wouldn't actually recommend chaining as a useful feature here, but it certainly can be applied.
