c# - Programmatically getting SQL Cluster Virtual Name -


I have written a Windows service to gather information from all my SQL Servers. The service is installed on every server, and the use of WMI and SMO brings back the information of the related system to a central database. To get SQL information, I use the following C # code: 

  list & lt; Server & gt; SqlServers = new list & lt; Server & gt; (); List of / Smo.Server Object String Registry SSubject = @ "Software \ Microsoft \ Microsoft SQL Server"; String registry value = "installed instances"; Try {Registry RK = Registry.LocalMachine OpenSubby (Registry Branch); String [] example = (string []) rk.GetValue (registryValue); If (e.g. Lang & gt; 0) {foreach (String Elements in Examples) {Server S; String server instant; If (element == "MSSQLSERVER") // If the default installation {serverInstance = System.Environment.MachineName; } And {serverInstance = system.Environment.MachineName + @ "\" + element; } S = New Server (Server Instance); If (s! = Null) {sqlServers.Add (s); }}}}

The only problem that is on our SQL cluster. For those people unfamiliar with active / inactive SQL clustering, you can not connect directly to any one of the nodes . Instead, the SQL cluster gets a virtual name and another IP address that the client will then connect to. I will try to connect the current code with NodeName \ instanceName which will not obviously work on the cluster. Instead, I need to find a program called SQL Cluster virtual name which is linked to this node and instead connect to it . I thought I could get this information from the MSCluster_Cluster WMI class, but it will only get me the cluster virtual name, not the SQL cluster virtual name. thank you in advanced.

With this code: 

  Using the system. Management; Management object explorer explorer = new management object search ("root \\ MSCluster", "SELECT * FROM MSCluster_Resource"); Foreach (Keywords in Management Object Query OBG.Get ()) {Console.WriteLine ("name: {0}", query.org ["name"]); }

I can see my SQL cluster name (2008CLUSTERSQL) as two outputs:

Name: SQL IP Address I (2008CLUSTERSQL)

Name: SQL Network Name (2008CLUSTERSQL)

Will this help? I think you can extract it out?

I got this code from the WMI code manufacturer, which is a very useful tool for browsing various WMI namespaces / classes / properties.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
