How to capture file not found exception in C#?
The file not found exception is raised when you try to find a file that does not exist.
Let’s say I have set a file in StreamReader, “new.txt” that does not exist. If you will try to access it using StreamReader(to read it), it will throw FileNotFoundException −
using (StreamReader sReader = new StreamReader("new.txt")) { sReader.ReadToEnd(); }
To handle it, you need to use try and catch −
Try { using (StreamReader sReader = new StreamReader("new.txt")) { sReader.ReadToEnd(); } }catch (FileNotFoundException e) { Console.WriteLine("File Not Found!"); Console.WriteLine(e); }
