Remove Last Character from String in C#

 The C# String.Remove method can be used to remove last characters from a string in C#. The String.Remove method in C# creates and returns a new string after removing a number of characters from an existing string.

 

C# String.Remove() method has two overloaded forms: 

1. Remove(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.
2.  Remove(Int32, Int32) - Returns a new string in which a specified number of characters in the current instance beginning at a specified position have been deleted.

Remove Last Character from a C# String

 

The following code example removes the last character from a string. 

1. /** Remove sample **/  
2. string founder = "Mahesh Chand is a founder of C# Corner!";  
3. // Remove last character from a string  
4. string founderMinus1 = founder.Remove(founder.Length - 1, 1);  
5. Console.WriteLine(founderMinus1);  

Remove All Characters After a Character Position

 

The following code example all characters after 25 characters. 

1. // Remove all characters after first 25 chars  
2. string first25 = founder.Remove(25);  
3. Console.WriteLine(first25);  

Remove All Characters In Between A C# String

 

The following code example removes 12 characters after 10th position in a string. 

1. // Remove characters start at 10th position, next 12 characters  
2. String newStr = founder.Remove(10, 12);  
3. Console.WriteLine(newStr);  
4. int pos = founder.IndexOf("founder");  
5. if (pos >= 0)  
6. {  
7. // String after founder  
8. string afterFounder = founder.Remove(pos);  
9. Console.WriteLine(afterFounder);  
10. // Remove everything before founder but include founder  
11. string beforeFounder = founder.Remove(0, pos);  
12. Console.Write(beforeFounder);  
13. }

Here is a Tutorial on C# String. 

 

Here is the complete source code of use of the C# String.Replace method. 

1. using System;  
2. namespace RemoveStringSample  
3. {  
4. class Program  
5. {  
6. static void Main(string[] args)  
7. {  
8. /** Remove sample **/  
9. string founder = "Mahesh Chand is a founder of C# Corner!";  
10. // Remove last character from a string  
11. string founderMinus1 = founder.Remove(founder.Length - 1, 1);  
12. Console.WriteLine(founderMinus1);  
13. // Remove all characters after first 25 chars  
14. string first25 = founder.Remove(25);  
15. Console.WriteLine(first25);  
16. // Remove characters start at 10th position, next 12 characters  
17. String newStr = founder.Remove(10, 12);  
18. Console.WriteLine(newStr);  
19. int pos = founder.IndexOf("founder");  
20. if (pos >= 0)  
21. {  
22. // String after founder  
23. string afterFounder = founder.Remove(pos);  
24. Console.WriteLine(afterFounder);  
25. // Remove everything before founder but include founder  
26. string beforeFounder = founder.Remove(0, pos);  
27. Console.Write(beforeFounder);  
28. }  
29. Console.ReadKey();  
30. }  
31. }  
32. }
