Check if a File exists using C#

If you want to check if a specific file exists on a local machine at a particular path using C# programming language, you can do so by using the File.Exists() method.

To use this first you need to import the System.IO namespace.

using System.IO;

Next, below is a sample code that checks if a file exists, first in the same directory and then in some different directory, in case of any doubts/suggestion feel free to use the comments section. CheersĀ !

using System;  
using System.IO;
class Program  
{
static void Main()
{
// See if this file exists in the SAME DIRECTORY.  
if (File.Exists("Yasser.txt"))
{
Console.WriteLine("The file exists.");
}
// See if this file exists in the C:YS directory.  
if (File.Exists(@"C:YSYasser.txt"))
{
Console.WriteLine("The file exists.");
}
}  
}
