c# variable access from many different classes-CodePudding

What is the common way to access a variable in c#, that is used by many different functions and classes? Should you just pass this variable to every class/function that needs it or should you better create a new instance of the class, that holds the variable and access it inside the class/function that needs to call the variable?

CodePudding user response：

It depends on on type of project and files hierarchy

One way is to create one Base class and inherit from it to every class your using

class BaseController
{
    string connectionString = "..." //this is your often used variable
}

class UsersController : BaseController
{
    Connect(connectionString);

    //rest of class
}

class GroupsController : BaseController
{
    Connect(connectionString);

    //rest of class
}

Another way is to create class with static varibles if you can and call them without class instance

class MyVariables
{
    static string connectionString = "..." //this is your often used variable
}

And call it like this

Connect(MyVariables.connectionString);

I think The second option is better
