method

I use this method to get file extension,

public string ReturnExtension(string fileExtension)
    {
        switch (fileExtension)
        {
            case ".doc":
            case ".docx":
                return "application/ms-word";
        }
    }

When i compile it i got the error BaseClass.ReturnExtension(string)': not all code paths return a value.. Any suggestion...

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
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
