Question

public class ItemStack
{
    public int stackSize;
    public int itemID;
    public int itemDamage;

    public ItemStack(Item item)
    {
        this(item.id, 1, 0); //ERROR HERE
    }

    public ItemStack(Item item, int value)
    {
        this(item.id, value, 0); //ERROR HERE
    }

    public ItemStack(Item item, int value, int value2)
    {
        this(item.id, value, value2); //ERROR HERE
    }

    public ItemStack(int value, int value2, int value3)
    {
        this.stackSize = 0;
        this.itemID = value;
        this.stackSize = value2;
        this.itemDamage = value3;

        if (this.itemDamage < 0)
        {
            this.itemDamage = 0;
        }
    }

    private ItemStack()
    {
        this.stackSize = 0;
    }
}

I don't know how solve this, if you have any idea please help me. Thanks. I don't have any idea how solve this, I tried differents ways but nothing. The errors are situated where you see "ERROR HERE" just these lines.

You're trying to chain constructors, that's not how you do that. You need call : this() in the constructor declaration:

public ItemStack(Item item) : this(item.id, 1, 0)
{
}

public ItemStack(Item item, int value) : this(item.id, value, 0)
{
}

public ItemStack(Item item, int value, int value2) : this(item.id, value, value2)
{
}
