Check if a File exists in C#
Use the File.exists method in C# to check if a file exits in C# or not.
Firstly, check whether the file is present in the current directory.
if (File.Exists("MyFile.txt")) { Console.WriteLine("The file exists."); }
After that check whether the file exist in a directory or not.
if (File.Exists(@"D:\myfile.txt")) { Console.WriteLine("The file exists."); }
Let us see the complete example to check if a file exists in C#.
Example
using System; using System.IO; class Demo { static void Main() { if (File.Exists("MyFile.txt")) { Console.WriteLine("File exists..."); } else { Console.WriteLine("File does not exist in the current directory!"); } if (File.Exists(@"D:\myfile.txt")) { Console.WriteLine("File exists..."); } else { Console.WriteLine("File does not exist in the D directory!"); } } }
Output
File does not exist in the current directory! File does not exist in the D directory!
