using namespace System; int main() { int i = -123; Object^ o = i; array<Object^>^objs = { -123, -456, -789}; Console::WriteLine("Concatenate 1, 2, and 3 objects:"); Console::WriteLine("1) {0}", String::Concat(o)); Console::WriteLine("2) {0}", String::Concat(o, o)); Console::WriteLine("3) {0}", String::Concat(o, o, o)); Console::WriteLine("\nConcatenate 4 objects and a variable length parameter list:" ); Console::WriteLine("4) {0}", String::Concat(o, o, o, o)); Console::WriteLine("5) {0}", String::Concat( o, o, o, o, o)); Console::WriteLine("\nConcatenate a 3-element object array:"); Console::WriteLine("6) {0}", String::Concat(objs)); } // The example displays the following output: // Concatenate 1, 2, and 3 objects: // 1) -123 // 2) -123-123 // 3) -123-123-123 // // Concatenate 4 objects and a variable length parameter list: // 4) -123-123-123-123 // 5) -123-123-123-123-123 // // Concatenate a 3-element object array: // 6) -123-456-789
