String::Concat Method (Object, Object, Object)
Visual Studio 2010
Concatenates the string representations of three specified objects.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- arg0
- Type: System::Object
The first object to concatenate.
- arg1
- Type: System::Object
The second object to concatenate.
- arg2
- Type: System::Object
The third object to concatenate.
Return Value
Type: System::StringThe concatenated string representations of the values of arg0, arg1, and arg2.
The method concatenates arg0, arg1, and arg2 by calling the parameterless ToString method of each object; it does not add any delimiters.
String::Empty is used in place of any null argument.
The following example demonstrates the Concat method.
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
