myArray.Add('+');
myArray.Add(10);
int myVariable = 0;
foreach(object obj in myArray){ // You can use "var" instead of "object"
if(obj is int) // You use the "is" keyword
myVariable += Convert.ToInt32(obj); // You need to convert the variable objet to what it contains for the compiler to accept this operation
if(obj is string)
Console.WriteLine(obj + " World");
}
Console.WriteLine(myVariable);
// .....2º Method.... //
