how to set flag value to true in data layer method and this flag value should return to calling method. cs file in C#

What I have tried:

In sql Datalayer.cs

C#

bool OrdInValid = false; int ordernum=0;
bool isValid = Int32.TryParse(dt.Rows[0].GetField<string>("Col1"), out int Coldata);
                        if (isPOValid)
                        {
                            ordernum= Convert.ToInt32(dt.Rows[0].GetField<string>("Col1"));
                            OrdInValid = false;
                        }
                        else
                        {
                            OrdInValid = true;
                        }

}

2. In Main window
property

C#

private int _Order;

        public int Order
        {
            get { return _Order; }
            set { _Order = value;
                if (ordernum==0)
                {
                    OrdInValid = true;

                }
                
            }
        }

Solution 1

Either create a property to return the value (you know how to do that, it's in your main window code), or return a bool value from a method:

C#

public bool MyMethod(...)
   {
   bool itWorked = false;
   ... do something ...
   return itWorked;
   }
