How to find out if a file exists in C# / .NET?

Use:

File.Exists(path)

MSDN: http://msdn.microsoft.com/en-us/library/system.io.file.exists.aspx

Edit: In System.IO

System.IO.File:

using System.IO;

if (File.Exists(path)) 
{
    Console.WriteLine("file exists");
} 

System.IO.File.Exists(path)

msdn

I use WinForms and my way to use File.Exists(string path) is the next one:

public bool FileExists(string fileName)
{
    var workingDirectory = Environment.CurrentDirectory;
    var file = $"{workingDirectory}\{fileName}";
    return File.Exists(file);
}

fileName must include the extension like myfile.txt
