Question

How to capture file not found exception in C#?

Answer 1

Answer:

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);

}
