Inner class and Outer class in c#

[pramodhts]

how to implement inner outer classes in c#

i have two nested classes

like

class Outer 
{ 
    int TestVariable = 0; 
    class Inner 
    { 
        int InnerTestVariable = TestVariable // Need to access the variable "TestVariable" here 
    } 
}

Its showing error while compiling.

It can be solved by

1) Making TestVariable as static

2) Passing an instance of Outer class to Inner class

but in java there is no need to create Instance or static .

can i use the same functionality in C# too ?
