从C＃中的另一个类访问方法

Question

I have a number of classes in a Classes file, and I want them all to be able to access the same, global method to save duplicating code. Problem is, I can't seem to access a method from another class in my file - any ideas?

So my class1.cs layout is similar to this:

public class Job1
{
    public Job1()
    {

    }
}

public class Methods
{
    public static void Method1()
    {
        //Want to access method here from Job1 
    }
}

Answer 1

You'll need to specify the class they are in. Like this:

public Job1()
{
  Methods.Method1()
}

If the class Job1 is in a different namespace from Methods then you'll need to either add a using clause, or specify the the namespace when calling the method. Name.Space.Methods.Method1()

Answer 2

Actually. Public Job1(){} is a constructor and not a method. It can be called from main class by creating object form the JOB1 class. Here add the following code:

public static void method1()
{
Job1 j1=new Job1();
}

constructor can be invoked by creating a object to the corressponding class....

Answer 3

To access methods of other classes, the methods must be static with a public Access modifier.

static - Not bound to an instance of the class but shared by all other instances.

private - data can only be accessed from inside the same class.

public - data can be accessed from other classes but must be referenced.
