Array size cannot be specified in a variable declaration (try initializing with a 'new' expression)_

Question

My intention is just to assign the value of 2 to the 0th or 1st element of this 8 byte array.  What am I missing here? thx.

Byte[] toSocket = new Byte[7];
toSocket[0] = 2 ; //msgID        Array size cannot be specified in a variable declaration (try initializing with a 'new' expression) 

Answer 1

The code you posted is valid for C#.  I don't think the code itself is what is causing the problem.  I suspect you might have tried to do something like this:

Byte[4] toSocket

or,

void Foo ( Byte[4] args )

which is not valid.

I tried this code.
I compiles, it should be something different.

(I compiled this code

  static void Main(string[] args)
        {
            Byte[] toSocket = new Byte[7];
            toSocket[0] = 2; //msgID
        }

)

Answer 3

I attempted this assignment in the following context which caused the error: 

 

public partial class Form1 : Form

{

 

              Byte[] toSocket = new Byte[7];

 

               toSocket[0] = 2; //msgID            error here

When I moved the assignment statement into a button click event, there was no error;

 

private void button1_Click(object sender, EventArgs e)

    {

            toSocket[0] = 2;

//msgID                no error here when I move this from class scope

Answer 4

You can't have non-declaration statements at the class level.
