Assigning values to a public byte array in one line C#

Assigning values to a public byte array in one line C#

I am working with a public byte array and would like to assign values,
like I assign arrays inside a method, i.e
byte[] foo = {0x32, 0x00, 0x1E, 0x00};
but when I define the values I am forced to do
foo[0] = 0x32;
foo[1] = 0x00;
foo[2] = 0x1E;
foo[3] = 0x00;
If I use the first example VS gives an error "Only assignment, call,
increment, decrement, await, and new object expressions can be used as a
statement"
If it helps any, the array is always 4 bytes.
my code
public byte[] SetSpeed = new byte[4];
private void trackBar1_Scroll(object sender, EventArgs e)
{
if (trackBar1.Value == 0)
{
try
{
stop = true;
UpdateSThread.Abort();
Thread.Sleep(350);
}
catch { }
SetSpeed = {0x00,0x00,0x00,0x00};
WriteMem(GetPlayer() + STATUS_OFFSET, SetSpeed);
label1.Text = "Normal";
}
}
