In C#, should I use string.Empty or String.Empty or “” ?
I just don't understand the benefits of using String.Empty over "". Aside it being strongly typed its longer.
So please, why should I be using this?
As has been mentioned string.Empty creates no object where as "" will create an object (albeit pulled out of the pool). The performance difference is minimal but the question should be what is more readable. I take the stance that string.Empty sticks out more than "" and I can clearly see the intent of the declaration (string.Empty vs null). Regardless of your choice you should be consistent throughout your code base.
String.Empty vs ""
There is no meaningful difference. See these (and other) questions elsewhere on SO:
In C#, should I use string.Empty or String.Empty or "" to intitialize a string?

Closed 4 years ago.
I want to handle "" and null while assigning value to the property of the class.
So how can i handle the same. Below is my example which works for null. But also want to handle empty string
Id = characater.Id ?? System.Guid.NewGuid().ToString(),
Use string.IsNullOrEmpty along with the ?: Operator.
Id = string.IsNullOrEmpty(characater.Id)
? System.Guid.NewGuid().ToString()
: characater.Id;
If you you also want to check for white space characters line spaces, line breaks, tabs, you can use String.IsNullOrWhiteSpace instead.

Why it is recommended to use string.Empty instead of ""? From one side, I understand, that it makes code clearer, without "Magic constants". Is there any another technical benefits of using string.Empty?
Thanks.
Per Brad Abrams blog:
the difference between String.Empty and “” are pretty small, but there
is a difference. “” actually creates an object, it will likely be
pulled out of the string intern pool, but still… while String.Empty
creates no object… so if you are really looking for ultimately in
memory efficiency, I suggest String.Empty. However, you should keep
in mind the difference is so trival you will like never see it in your
code…
It's pretty insignificant.
I believe this has been answered before, but to summarize: preference and readability.
They are completely equivalent, and are up to whatever you and your fellow developers prefer, just be consistent. :)

Hello
Simple Question;
Why
Textbox1.Text = String.Empty;
is better than
Textbox1.Text = "";
?
It's not, really.
Basically, decide which you find to be more readable. Personally I use "" instead of string.Empty, but others prefer the latter.
Back in .NET 1.x days apparently there was some tiny performance difference (almost certainly irrelevant in real apps) but I believe these days even that's gone.
Use whichever you and your find most readable.
Because String.Empty is actually defined as ""
Best practices dictate not to use string literals but constants.
On a funnier note: String.Empty is/looks more Object Oriented-ISH.

Is there any difference in c# between the following declarations...
private string m_port = string.Empty;
or...
private string m_port = "";
Is it just coding standard that makes it look neater?

They are the same, but looks better.
The main difference is one of semantics - string.Emtpy says that you meant to have an empty string. "" might be a mistake (" ", for instance).
Since String.Empty is an instance it should remove the overhead of the object creation, however I think a parser should be smart enough to figure this out.
All string literals is also pulled from an object pool I believe, so the object creation might not even take place.

Should I use:
- string.Empty
- String.Empty
- ""
when I want to return an empty string from a method (or anywhere else for that matter)
String.Empty & string.Empty are exactly the same.
