If we are 'using' multiple namespaces which have a Class with the same title, how will the compiler know which to use?

For example, say I am

using System; using someOtherNamespace;

and a class exists in both namespaces called "Console", and in both classes there is a method called "Write" which do slightly different things. When I write the following code, how will the compiler know which namespace to "use"?

Console.Write("Hello");

If your methods have the same signature (number and type of parameters), the compiler will probably complain about an ambiguous reference. You will then have to fully qualify the name using the namespace:

    System.Console.Write("Hello");  // or ....
    someOtherNamespace.Console.Write("Hello");

Hi!

Usually the classes and methods will be distinguished by it's parameters. 

public void newStr(String a){
     console.print(a);
}

public void newStr(String a, String b){
     console.print(a + b);   
}

These both have the same method name, but the params are different.
