Good explanation...

Yes I agree with Sanjay. The Topic is very good but would have been more better with some simple examples. Thanks

Very good Topic but would have been more better with some simple examples. Thanks

Nice article Vikram, as always!!Very specific, Just one thing I would request you, could you explain this a bit elaborately, I mean with examples?

Very nice. I can understand with out even examples

example is needed for better explanation, thanks

Very well explanation. It clear the concept of ref param and out param.

Its very helpful.Thanks

Its very helpful.Thanks

Yes,Examples are required then it will become best.

Examples
namespace ParametersDemo
{
class ParametersDemo
{
class Calculator
{
public void AddAndSubtract(int num1,int num2,ref int sum,ref int diff)
{
//sum = num1 + num2;
//diff = num1 - num2;

}
}
static void Main(string[] args)
{
int sum=4,diff=3;
Calculator objCalc = new Calculator();
objCalc.AddAndSubtract(20,10,ref sum,ref diff);
Console.WriteLine("{0},{1}",sum,diff);
}
}
}

o/p 4,3

namespace ParametersDemo
{
class ParametersDemo
{
class Calculator
{
public void AddAndSubtract(int num1,int num2,out int sum,out int diff)
{
sum = num1 + num2;
diff = num1 - num2;

}
}
static void Main(string[] args)
{
int sum,diff;

Calculator objCalc = new Calculator();
objCalc.AddAndSubtract(20,10,out sum,out diff);
Console.WriteLine("{0},{1}",sum,diff);
}
}
}
o/p 30,10

Good Explanation.

Any idea about the difference in performance b/w the out and ref parameter.

its good bt an example is required for better undrstandig....
