I have 2 samples that effectively do the same thing -- Sample 1:

command.Parameters.Add(ParamFoo, SqlDbType.Int)
command.Parameters(ParamFoo).Value = fooVal

Sample 2:

command.Parameters.AddWithValue(ParamBar, barVal)

Which sample would be recommended? I know that the second sample is making some conversions. Wouldn't it be best to not require conversions and go with the first sample?

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
