How do you get the number of bytes in a string


What is the C# code that returns the number of bytes in a string such as

323131313531313 33432317E547E31 32357E5553447E4 67E353636303130 303034383532363 2

It should be 80 I think.

damn, you're right.

I meant to type System.Text.Enc oding.Ascii.Get Bytes(value)

I guess you can do
int length = value.Length * 2;
since a char is 2 bytes, and a string stores chars only.

byte[] data = System.Text.Enc oding.GetBytes( value);
int length = data.Length;


That won't work quite as you've posted it because you need to say
*which* encoding to use - Encoding.GetByt es is an instance method, not
a static method.

That still wouldn't work because Ascii should be ASCII, but I get the
idea :)

But that gets the number of bytes in the internal representation - it
doesn't get the number of bytes written when the data is encoded.

I have the need to preserve the precision of a user-entered number, but that needs to be stored in a (non-string) floating point variable (such as double or decimal). Due to the internal limitations of numerical precision of the double type, I'm presuming that the value will be stored in a decimal for the time being. Supposing the following: decimal d1 = 123.45; decimal d2 = 888.1234567;
