Why Does .NET Add Extra Slashes to Paths?

Explanation of extra slashes in .NET paths

In .NET, when assigning a path to a string (e.g. using C:\Test), it is often observed that extra slashes are added to the end of the path. However, when viewing the string in a text visualizer, it appears as C:\Test.

This behavior can be confusing, especially when considering how to use string.Split() to split paths. Understanding the reasoning behind this can help clarify the correct way to handle paths in your code.

The reason for the extra slash in

is that in C#, the backslash is an escape character. This means that when the compiler encounters a backslash, it interprets it as a special character rather than a literal slash.

Specifically, \ is used to represent a single character. Without the first backslash as an escape character, the second backslash will be interpreted as an escape character and the result will not be a valid path.

It is important to note that this behavior applies to all escape characters in C#. Some common escape characters include:

• \': single quote
• \": double quotes
• \: backslash
: Null
• \a
: Alert
• \r
: carriage return
• \t
: horizontal tab

SplitWhen using the \ method, you can use it as normal.

will be treated as a single character representing a backslash. So splitting by extra slashes doesn't create any problems.
