Question

I am reading strings from a binary file. Each string is null-terminated. Encoding is UTF-8. In python I simply read a byte, check if it’s 0, append it to a byte array, and continue reading bytes until I see a 0. Then I convert byte array into a string and move on. All of the strings were read correctly.

How can I read this in C#? I don’t think I have the luxury of simply appending bytes to an array since the arrays are fixed size.

You can either use a List<byte>:

List<byte> list = new List<byte>();
while(reading){ //or whatever your condition is
    list.add(readByte);
}

string output = Encoding.UTF8.GetString(list.ToArray());

Or you could use a StringBuilder :

StringBuilder builder = new StringBuilder();

while(reading){
    builder.Append(readByte);
}

string output = builder.ToString();
