Question

I have the following test that I’ve been trying to get working

[Test]
public void Test()
{
    byte[] testArray = new byte[] { 1, 0, 0, 1 };

    string number = System.Text.Encoding.ASCII.GetString(testArray);

    Assert.That(number, Is.EqualTo("1001"));
}

I get the following error

String lengths are both 4. Strings differ at index 0.
Expected: "1001"
But was:  "\0\0"

This puzzles me because my production code that converts a byte array to a string uses the same method then I log out the string and it’s what I would expect.

Should I be doing something to the byte array before doing the conversion in this case?

Thanks, Neil

Answer 1

Byte 0 in ASCII is not “0” but some escape character.

This will probably fix your issue;

byte[] testArray = new byte[] { 49, 48, 48, 49 };
