How to remove "DESKTOP-OK4L9CB\" from DESKTOP-CK9M9CB\Subash Dash

Supporting to @Amit's code snippet submission: 

Input String:
string input = "DESKTOP-CK9M9CB\\Subash Dash";
 

A string variable named `input` is declared and assigned the value `"DESKTOP-CK9M9CB\\Subash Dash"`. It represents a computer name followed by a backslash (`\`) and a user name.

Output String:
string output = input.Substring(input.IndexOf('\\') + 1);
 

A new string variable named `output` is declared. The `Substring` method is used to extract a portion of the `input` string starting from the character after the backslash (`\`). 

The `IndexOf` method is used to find the position of the first occurrence of the backslash (`\`) within the `input` string. The `+ 1` is added to start the substring from the next character after the backslash. This is because `IndexOf` returns the zero-based index, and adding 1 moves the starting point of the substring to the character after the backslash.

Check this:

string input = "DESKTOP-CK9M9CB\\Subash Dash";
string output = input.Substring(input.IndexOf('\\') + 1);
Console.WriteLine(output);
