Question

I am new to C# and programming in general my question is how do you call a variable that is in a different namespace? if I have this code

public void servicevalues(string _servicename) {   string servicename = _servicename;   string query = string.Format('SELECT * FROM Win32_Service WHERE Name ='{0}'', servicename);   ManagementObjectSearcher moquery = new ManagementObjectSearcher(query);   ManagementObjectCollection queryCollection = moquery.Get();   foreach (ManagementObject service in queryCollection)   {     string serviceId = Convert.ToString(service['DisplayName']);     bool serviceResult = Convert.ToBoolean(service['Started']);   } 

and I am passing in service name how would I call one or multiple variable values from a different namespace?

Normally, variables don’t live in a namespace alone, they live inside another class that could be in another namespace. If you need to access a variable in another class (in another namespace), your other class needs to expose the variable somehow. The common practice for this is to use a public Property (static if you only need access to that variable) for the variable.

namespace My.Namespace {     public class MyClassA     {         public void MyMethod()         {             // Use value from MyOtherClass             int myValue = My.Other.Namespace.MyOtherClass.MyInt;         }     } }  namespace My.Other.Namespace {     public class MyOtherClass     {         private static int myInt;         public static int MyInt         {             get {return myInt;}             set {myInt = value;}         }          // Can also do this in C#3.0         public static int MyOtherInt {get;set;}     } }
