Remove characters from a String
The String represents text as a sequence of UTF-16 code units. The
String is a sequential collection of characters that is used to represent
text. The String is a sequential collection of System.Char objects.
The following .net c# tutorial code demonstrates how we can remove characters from a String instance. So, in this .net c# tutorial code we will remove a specified number of characters from a String object from the specified character position. Here we will use String Remove() method to do this.
The String Remove() method returns a new String in which a specified number of characters from the current String are deleted. The String Remove() method has two overloads.The String Remove(int startIndex) 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. So using this overload we can delete all the characters from a String after a specified index position.
The String Remove(int startIndex, int count) method overload returns a new String in which a specified number of characters in the current instance beginning at a specified position has been deleted. So using this overload we can delete a specified number of characters from a String instance at the specified index position.
