Convert versus parse

[Patrick De Ridder]

s is a string
f is a single precision float

f = float.Parse(s);// (a)
f = Convert.ToSingle(s);// (b)

Is (a) just as good as (b)?
If one should be used, not the other, please give the reason.

They are the same. In the doc it says:

The return value is the result of invoking the
Single.Parse method on value.

In other words, Convert will just call Parse anyways.

Hi,

One difference to keep in mind is that Convert.ToSingle(string s) will
check the in-comming value and if it is a null reference it will return
0, while float.Parse(string s) will throw an ArgumentNullException if
the value passed is a null reference.
