Yeah, not sure which is better, Java's or C#'s varargs, but it does make
things nicer at times. In C#, the method signature signature screams "I AM
passing an array", but you can pass arguments either way as in Java.
C#:
----------------
public void UseVarargs(params int[] args)
{
// Do something using argument array
}
public static void Main()
{
UseVarargs(1);
UseVarargs(1, 2, 3);
UseVarargs(new int[3] {1, 2, 3});
}
C#:
----------------
public void UseVarargs(params int[] args)
{
// Do something using argument array
}
public static void Main()
{
UseVarargs(1);
UseVarargs(1, 2, 3);
UseVarargs(new int[] {1, 2, 3});
}
Java:
----------------
public void useVarargs(int... args) {
// Do something using argument array
}
public static void main(string [] args) {
useVarargs(1);
useVarargs(1, 2, 3);
useVarargs(new int[] {1, 2, 3});
}
