Difference between String.Empty, Empty Quotes and String.length

Hi
A few days back when I was working with string. At many point of time I had to make a checking for empty string. I started thinking about the difference between “” and string.empty. and which one is a better way to check if the string is empty or not.
The difference between string.Empty and “” is very small. String.empty will not create any object while “” will create a new object in the memory for the checking. Hence string.empty is better in memory management.
But the comparison with string.length == 0 will be even faster and the better way to check for the empty string. And I also have a bias for checking with string.length in this case. But do not forget to make a checking for null value if you are also expecting null value in the comparison.
Happy coding
Vikram

Have you tried string.IsNullOrEmpty()?

Smart, you mention check for null,
then you could use string.IsNullOrEmpty checking null and empty

Hi,
unfortunately it seems that - even in the AjaxControlToolkit Demos - the AlwaysVisibleControl, just like the DragPanelExtender don't show up on top of everything. In my case this would be ListBoxes, in the demo project this is the ComboBox to select where the control should appear.
