convert VB.net Module to C#

Question

I decided to try out C# for the first time after using VB.net.

Out of curiousity, when I used VB.net I had :

Dim conn As OleDbConnection = New OleDbConnection("Provider=""****"";user id=" & strUserID & ";data source=" & strDatabase & ";password=" & strPssWd)

When trying to convert this format to C# I did the following:

string strAccessConn = "Provider=****;user id=" & strUserID & ";data source=" & strDatabase & ";password=" & strPssWd

However, my strUserId, strDatabase and strPssWd where saved in my Module.vb for VB.net like so:

Module Module1
  Friend strDatabase As String = "****"
  Friend strUserID As String = "****"
  Friend strPssWd As String = "****"

End Module

How do I make the Module in C# (an example would be helpful) Thanks!

FYI: I was told C# Equivalent for VB 'module' was a duplicate.

However the formatting and process of their post isn't equivalent to mine. I am asking a module based on database connection.

You can put constants in a public static class like this:

public static class MyConnectionStringConstants
{
    public const string strDatabase = "****";
    public const string strUserID = "****";
    public const string strPssWd = "****";
}

To use it, you will need to refer to the constants like this:

string strAccessConn = "Provider=****;user id=" + MyConnectionStringConstants.strUserID + ";data source=" + MyConnectionStringConstants.strDatabase + ";password=" + MyConnectionStringConstants.strPssWd

BTW, in C#, you concatenate strings using the + operator, not the & operator.
