Image extension validation c#

By Mash B

Logic to validate the image extension

You can make use of regular expression for simplicity of code

// the regex for an image
Regex imageFilenameRegex = new Regex(@"(.*?)\.(jpg|jpeg|png|gif)$");
  
  if (imageFilenameRegex.IsMatch("Your FileName or Path here",RegexOptions.IgnoreCase))
  {
    // we have a valid filename
    // .. do something ..
  }
