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

Question

I would like to test a string containing a path to a file for existence of that file (something like the -e test in Perl or the os.path.exists() in Python) in C#.

Answer 1

Use:

File.Exists(path)

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

Edit: In System.IO

Answer 2

System.IO.File.Exists(path)

msdn

Answer 3

System.IO

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