You do realise we can all see you talking to yourself, don't you? D'Oh! | :doh:

Quote:
string extension = ((System.Web.HttpPostedFileBase)value).FileName.Split('.')[1];

Lots of problems with that line. For example, what if the uploaded file doesn't contain an extension? What if it contains multiple "." characters? What if the extension is .lsx? Etc.

Try:
C#
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
    var file = value as System.Web.HttpPostedFileBase;
    if (file != null)
    {
        string extension = System.IO.Path.GetExtension(file.FileName);
        string[] allowedExtensions = Allow.Split(',');
        if (!Array.Exists(allowedExtensions, ext => string.Equals(ext, extension, StringComparison.OrdinalIgnoreCase)))
        {
            return new ValidationResult(ErrorMessage);
        }
    }
    
    return ValidationResult.Success;
}
