how to use variable form other class? C#

[ping_jacob]

if i need to use variable form other class & other file but same namespace & project how to use that variable? example: --file1-- class A { public string a = "aaa"; } --file2-- class B { if(a = "aaa") {}} please hint to me... thank so much...

class B
{
public void SomeMethod()
{
if (A.a = "aaa")
{
DoSomeStuff();
}
}
}

The A class needs to be public for this to work if the classes have different namespaces. The A class can also be internal if the namespace of the two classes is the same.

This is so rudimentary that you really need to buy a book and work through it, before you try to write any code that's not a book example.

Hi, You need to create an instance from class A so you can use its public members. In this case you should write:

public class A
{
public string a = "aaa";
}

public class B
{
A Ainstance = new A();
if(Ainstance.a = "aaa") {}
if (Ainstance.a == "aaa") { ;}
}

If variable a (or any member in your class) is static, you can use it from class B without creating an instance. Just like:

public class A
{
public static string a = "aaa";
}

class B
{
if(A.a = "aaa") {}
if(A.a == "aaa") { ;}
}

Hope can help :)

use internal variable to access it from same namespace.
