Copy file from one directory to another

Question

I am pretty new to C# and I am trying to get my program to copy a file from one location to another. The method I have is as below;

    private void CopyInstallF         


        

Answer 1

This is because in C# (and C++ and C and some other languages) string can contain special characters. Those characters are followed by '\'. So for example string:

"\n"

Will not show you \n This is special character called - new line. So, when you create path like that:

"C:\Dir\file.txt"

C# expects that there are two special characters: \D and \f. But there is no special characters like that. Thus the error.

To put character '\' into string you have to double it, so:

"\\n"

would output \n

The same is with paths: "C:\Dir\file.txt"

C# has an alternative. You can have single '\' in path, but such a string must be followed by at sign (@):

string properPath = @"C:\dir\file.txt";
string properPath2 = "C:\\dir\\file.txt";
string error = "C:\dir\file.txt"
