convert from int to byte

Question

Hello, I got the error:

System.ArgumentException: Object must be of type Int32.

in this code:

MyBO target = new MyBO() { x1 = 20 };

In MyBO i have an attribute: public byte x1 {get; set;}

What's wrong? I tried with MyBO target = new MyBO() { x1 = (byte)20 }; but i got the same error. Please help.

Thanks!

Answer 1

Have you tried explicitly casting to a byte?

---

MyBO target = new MyBO() { x1 = (byte) 20 };

Answer 2

MYBO target=new MyBO();
target.x1=Convert.ToByte(20);

Answer 3

Are you sure that error comes from that line? I run this code without problems:

class MyBO
{
    public byte x1 { get; set; }   
}

// ...
public static void Main(string[] args)
{
    MyBO my1 = new MyBO() {x1 = 20};
    MyBO my2 = new MyBO() {x1 = (byte)20};
    MyBO my3 = new MyBO() {x1 = Convert.ToByte(20)};
}
