More Efficient Way of Adding Parameters to a SqlCommand .NET

Question

I was just reading a question about how to add parameters to a SqlCommand in .NET, and it raised a question for me. In all of my programs, this is how I add parameters to m

Answer 1

This is how I am doing it in code:

cmd.Parameters.AddWithValue("@name", value);

Answer 2

here is my way

cmd.InjectFrom<SetParamsValues>(foo);

all the properties foo (I sometimes use anonymous, and you can also specify ignores ) are going to be AddWithValue to the cmd, and for null DBNull.Value is going to be set

I recommend you too look at samples project from here http://valueinjecter.codeplex.com/ (it contains DAL sample)

Answer 3

Both ways are going to create objects - whether you call the constructor yourself or whether another method does, the object is still going to be created.

More importantly, however, you're about to make a database call. The cost of creating a dozen objects is going to be absolutely peanuts compared with the database call, even if it's a very fast call.

Don't worry about it - just use the most readable code.
