Global Variables

I'm quite new to C#, and wanted a bit of advice really on best practice.

I come from a vb background, and am used to having a declarations module, where I can add any global contansts, global ADO connections etc that can be used by the whole program.

I'm having some difficulty doing the same thing in C#. I've tried including a declarations class with the same namespace as every other class. Here I can put global enumerations which works well, but I can't seem to put global variables here.

Basically I just want a place to delcare my global SQL Connection. Can anyone suggest a good approach?

Hi JezzaKashel,

Something like this

public class myGlobals
private string sConString;

public string conString {
 get {
   return sConString;
 set {
   sConString = Value;

C# doesn't allow global variables, but you can use static class members, they provide the same functionality.

public class GlobalData         // like VB module
    public static string connectionString;

    // other data

public class AnyOtherClass
    void SomeFunction()
         // use GlobalData.connectionString here

Thanks for all the comments.

Seem to remember static class members is the way forward, so will give it a go and see what happens
