Hi All,

I need to concatenate "@" symbol to a string in C++/CLI as follows.

Ex:

C++

String^ str1 = "OXF";
 String^ str2 = "@"+ str1;

But i am getting compile errors saying as follows: Could you please let me know how to resolve them.

VB

NotificationManager.cpp(127) : error C2018: unknown character '0x40'
NotificationManager.cpp(127) : error C2065: '"': undeclared identifier
NotificationManager.cpp(127) : error C2146: syntax error : missing ';' before identifier '"'
NotificationManager.cpp(127) : error C2065: '"'  : undeclared identifier

Thanks,
Sudhakar

You most probably have something missing before these lines of code. Take a closer look at what you have written.

My problem is , I am not able to concatenate "@" symbol to another C++/CLI string.
Any ideas on how to concatenate "@" to a C++/CLI string (i.e) String^ sample="Hello";

Appreciate your help.
Thanks,
Sudhakar

I just tried it and it works fine. It must be something different in your source module, or project settings.

I tried as below and it worked with single quote. instead of double quotes in my dev environment.
String^ str1 = "OXF";
String^ str2 = '@'+ str1;

I tried and it worked with double quotation also now "@". Thanks a lot.

String^ targetLocation = "@" + "Hello".

Seems strange to me as well. now it is working with "@" . Thanks.

Like Richard, I tried your code, namely

C++

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
    String^ str1 = "OXF";
    String^ str2 = "@" + str1;
    Console::WriteLine(str2);

    return 0;
}

compiles and runs fine on my PC.

Possibly there is something wrong in your compilation environment.

That's pretty strange in my opinion. Could be you had a stray character in your original code?

Member 3975629 14-Aug-15 3:25am

I just copied the code from your snippet and tried and it worked with double quotation also "@". Thanks a lot.

String^ targetLocation = "@" + "Hello".

Seems strange to me as well. now it is working with "@" . Thanks.
