Question

I have a DataGridView that is bound to a BindingList of objects and I need to access the value of a particular cell in each row as quickly as possible. Is it faster to do:

if (((ObjectType)row.DataBoundItem).StringProperty != string.Empty)
{
}

…or…

if (row.Cells["STRINGPROPERTY"].Value != string.Empty)
{
}

Or is there another way that’s faster than both of these?

Answer 1

There’s a lot of way to check the value with if is empty or null but from your main question you can go and try to Benchmarking method calls in C#

1. String.IsNullOrEmpty
2. String.IsNullOrWhiteSpace
3. Best way to check if column returns a null value (from database to .net application)
