In this example we will show you how to check for the existence of a file in C#
Example
The existence of the file is checked using the File.Exist function with a Boolean variable. We then display a message depending on whether the file exists or not
You can change the code to select a file on your own system from J:\\csharp\\testfile.txt
using System;
using System.IO;
using System.Text;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
FileInfo info = new FileInfo("J:\\csharp\\testfile.txt");
bool exists = info.Exists;
if (exists == true)
{
Console.WriteLine("The File Exists");
}
else
{
Console.WriteLine("File not found");
}
Console.Read();
}
}
}
