System.IO.Path Class
Namespace: System.IO
Summary
Provides methods for creating, manipulating, and processing instances of Path, which represent file or directory paths.
Remarks
The Path class is a static class, meaning you do not create an instance of it. All members of the Path class are static members.
It is important to note that this class handles path data in a manner that is compatible with the underlying file system, but it does not interact with the file system itself. For example, Path.GetFileName does not return null for a non-existent file name.
To work with file system entries, use classes such as File, Directory, and FileInfo.
Methods
Path.Combine(string path1, string path2)
Summary
Concatenates two paths and returns the combined path.
Remarks
This method is overloaded to accept any number of path segments.

| Name | Type | Description |
