How to display global variable on messagebox?

This is written code,

void horizontal_calculate()
{
    String ^aa = filenames[0];
    std::string file1(marshal_as<std::string>(aa));
    String ^bb = filenames[1];
    std::string file2(marshal_as<std::string>(bb));

    double Result3=horizontal_read(file1);
    double Result4=horizontal_read(file2);
    double result=Result3/Result4;
    result1=result;
    System::Diagnostics::Debug::WriteLine("{0}",result);
}

private: System::Void button4_Click(System::Object^  sender, System::EventArgs^  e) {


             for (int i = 0; i < filenames->Length; i++)
                 System::Diagnostics::Debug::WriteLine(filenames[i]);

             semicircle();
             horizontal_calculate();
             oblique();


             MessageBox::Show("Time Ratio = "result1"","Screening Result",MessageBoxButtons::OK, MessageBoxIcon::Information);
         }

I have declared double=result1 as global variable.

It comes out an error "error C2146: syntax error : missing ')' before identifier 'result1'", so how am I going to solve this?

is it needed and how's the way to convert double to string?

Thanks all.

If the problem is in MessageBox line, write it by the following way:

MessageBox::Show(
    String::Format("Time Ratio = {0}", result1),
    "Screening Result",
    MessageBoxButtons::OK, MessageBoxIcon::Information);
