Hi mates,

I have a problem recently. My prog is under C++/CLI WinForm App. I noticed that here when file path are used, they should be like:
"C:\\folder1\\underfolder\\file.JPG"
unlike C# and VB:
C#:   @"C:\folder1\underfolder\file.JPG"
 
VB:   "C:\folder1\underfolder\file.JPG"

The difference is between "\" and "\\".
That means, when you use "C:\folder1\..." to call or write a file, it's not acceptable in C++/CLI.
I used folderbrowserdialog to get the folderpath, which gets paths in form of
"C:\folder\...":
folderBrowserDialog1->ShowDialog();
String^ path = folderBrowserDialog1->SelectedPath;
\\ path = path->Replace("\", "\\"); 
textBox1->Text = path;

And then I want to replace the "\" into "\\" of the paths. The method I used is String.Replace(). But there is problem. The Replace() must be used in two ways:
1. Replace('a', 'b');
2. Replace("docment", "document");

But the replace of "\" to "\\" is not going to work. I am really confused.
Could you tell me how to solve it? Maybe there is other ways? Or was I wrong?
Is it a general problem in c++/cli that the paths must be used with "\\"?

Thanks in advance and happy Halloween!

Escape the backslashes by repeating them: Replace("\\", "\\\\");
