regex

When i use a file upload i use to check file contenttype with regular expressions... For ex

private bool IsImage(HttpPostedFile file)
    {
        if (file != null && Regex.IsMatch(file.ContentType, "image/\\S+") &&
          file.ContentLength > 0)
        {
            return true;
        }
        return false;
    }

This returns my file is an image or not... How to check it is a word(.doc/.docx) document or not using c#...

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
