+5. but inside lambda expression you can just say n.ToString() instead of convert.ToString(n)

Convert.ToString is always a better option. In case n is null, tostring will throw an error.

Yes right.But i believe here we are trying to convert an integer tp string, there are no chances of having null as a value unless if its nullable int.

That is correct.
private void TestMethod(int[] intArray)
{
   string[] stringArray =
   Array.ConvertAll<int,string>
   (intArray,new Converter<int,string>
   (ConvertIntToString));

  // string result = string.Join(",", stringArray);
}

private string ConvertIntToString(int intParameter)
{
   return intParameter.ToString();
}
