Why does Path.Combine produce this result with a relative path?

Question

To my surprise, this code does not produce expected results:

var basePath = @\"\\\\server\\BaseFolder\";
var relativePath = @\"\\My\\Relative\\Folder\";

var         


        

Answer 1

Paths that start with a slash are interpreted as being absolute rather than relative. Simply trim the slash off if you want to guarantee that relativePath will be treated as relative.

var basePath = @"\\server\BaseFolder";
var relativePath = @"\My\Relative\Folder";

var combinedPath = Path.Combine(basePath, relativePath.TrimStart('/', '\\'));
