[RESOLVED] [2.0] Structure constructor

[Andy_P]

I have an error with the constructor in this structure:

    public struct CommsResponse
    {
        private byte header;
        private byte cmdCode;
        private int length;
        private List<byte> data;
        private byte terminator;

        CommsResponse()
        {
            this.Clear();
        }

        public void Clear()
        {
            this.header = 0;
            this.cmdCode = 0;
            this.length = 0;
            this.terminator = 0;

            if (this.data != null)
            {
                this.data.Capacity = 1024;
                this.data.Clear();
            }
            else
            {
                this.data = new List<byte>(1024);
            }
        }

        public byte Header
        {
            get { return this.header; }
            set { this.header = value; }
        }

        public byte CommandCode
        {
            get { return this.cmdCode; }
            set { this.cmdCode = value; }
        }

        public int Length
        {
            get { return this.length; }
            set { this.length = value; }
        }

        public List<byte> Data
        {
            get { return this.data; }
            set { this.data = value; }
        }

        public byte Terminator
        {
            get { return this.terminator; }
            set { this.terminator = value; }
        }
    }

The compiler is complaining about the constructor because it is parameterless, and a parameterless constructor always gets created by default for a structure.

How should I call the Clear() method when the structure is created? I only really need to do this because of the 'List' field which needs to be created 'new' to initialize it, otherwise I wouldn't need a constructor at all.

I thought about making a constructor with a parameter that does nothing, but that doesn't seem very elegant somehow.

Any advice appreciated, thanks.

That type should not be a structure. Any type that has a collection as a member should be a class.

Yes, I guess that does make sense actually. Thanks.
