Scenario: Download Script
You are working as C# or dot net developer. You are writing a program in which you need to remove last x characters from a string.
To make it more real time problem, think about a scenario where you read text or csv files from a folder and then you need to remove the extension that is 4 characters (.csv or .txt).
The below code can be used to remove x characters from a string. Replace 4 with your number or characters you would like to remove.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//add namespace
using System.IO;
namespace TechBrothersIT.com_CSharp_Tutorial
{
class Program
{
staticvoid Main(string[] args)
{
//declare FileName variable and save mytextfile.txt value
string FileName = "mytextfile.txt";
//create variable FileNameRemoved and save values after removing last 4 characters from FileName variable
string FileNameRemoved = FileName.Substring(0, FileName.Length - 4);
//Print the variable values
Console.WriteLine("FileName Variable Value: " + FileName);
Console.WriteLine("FileNameRemoved Variable Value: " + FileNameRemoved);
//If we want to remove the last x characters and save in the same variable
FileName = FileName.Remove(FileName.Length - 4, 1);
Console.WriteLine("FileName Variable Value by using Remove and save to save variable: " + FileName);
Console.ReadLine();
}
}
}
Here is output after removing 4 characters from a string value in C#.
