Can anyone tell me the number of bytes each string takes in C#?

That is: if I have:

Then, how many bytes does the variable value take?

Because, if I have:

If I want to convert to convert value into into a c# byte array how many bytes does it take?

Know the answer? Post it — somebody with the same question will find it here.

It is the same account you read, post and publish with — and you will come straight back to this page.

Because you are using Encoding.ASCII, it is showing 4. If you use Encoding.Unicode it will show 8.
Remember that by design and default, Strings in C# are unicode, hence double the count.
Hope that helps!

You can easily get it counted in C#.

Each character is taking 1 byte according to me
Because, if I have 4 characters : "NONE", the byte array returned through the below code has byte array of dimension 4.. Can anyone confirm if this is right?
stringval="NONE"
byte[]b=Encoding.ASCII.GetBytes(val);
