Several methods and functions that are easy to ignore but important in ASP. NET are introduced.

We will introduce several methods of the Path class in. NET:

1. Path. combine (string, string)
Returns a path based on the given two paths.
For example:
String CompletePath = System. IO. Path. Combine (@ "c: \ MyApp", @ "Images \ skyline.jpg ");
A full path c: \ MyApp \ Images \ skyline.jpg will be returned.
The first parameter can end.

2. Path. GetExtension (string)
Returns the extension of the given file path. For example:
String FileExtention = System. IO. Path. GetExtention (@ "C: \ MyApp \ Images \ skyline.jpg ");
Will return "jpg"

3. Path. GetFileName (string)
Give the full path of the file name, and return the file name (including the extension). For example:
String fileName = System. IO. Path. GetFileName (@ "c: \ MyApp \ Images \ skyline.jpg ");
"Skyline.jpg" is returned"
