Concatenates the string representations of four specified objects and any objects specified in an optional variable length parameter list.
This API is not CLS-compliant.
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.
- arg3
-
Type:
System::Object^
The fourth object to concatenate.
- …
An optional comma-delimited list of one or more additional objects to concatenate.
Return Value

 Note |
|---|
This API is not CLS-compliant. The CLS-compliant alternative is String::Concat(array<Object^>^). The C# and Visual Basic compilers automatically resolve a call to this method as a call to String::Concat(array<Object^>^). |
The method concatenates each object in the parameter list by calling its parameterless ToString method; it does not add any delimiters.
String::Empty is used in place of any null argument.
| Note |
|---|
The last parameter of the Concat method is an optional comma-delimited list of one or more additional objects to concatenate. |
Notes to Callers:
This method is marked with the vararg keyword, which means that it supports a variable number of parameters. The method can be called from Visual C++, but it cannot be called from C# or Visual Basic code. The C# and Visual Basic compilers resolve calls to Concat(Object^, Object^, Object^, Object^) as calls to Concat(array<Object^>^).
