read last 3 characters from string [Initially asked question]

You can use string.Substring and give it the starting index and it will get the substring starting from given index till end.

myString.Substring(myString.Length-3)

Retrieves a substring from this instance. The substring starts at a specified character position. MSDN

Remove last 3 characters from string [Updated question]

To remove the last three characters from the string you can use string.Substring(Int32, Int32) and give it the starting index 0 and end index three less than the string length. It will get the substring before last three characters.

myString = myString.Substring(0, myString.Length-3);

String.Substring Method (Int32, Int32)

Retrieves a substring from this instance. The substring starts at a specified character position and has a specified length.

You can also using String.Remove(Int32) method to remove the last three characters by passing start index as length - 3, it will remove from this point to end of string.

myString = myString.Remove(myString.Length-3)

String.Remove Method (Int32)

Returns a new string in which all the characters in the current instance, beginning at a specified position and continuing through the last position, have been deleted

myString = myString.Remove(myString.Length - 3, 3);

I read through all these, but wanted something a bit more elegant. Just to remove a certain number of characters from the end of a string:

string.Concat("hello".Reverse().Skip(3).Reverse());

output:

"he"
