Solution 1

A decimal will always have some default value. If you need to have a nullable type[^] decimal, you can use decimal?. Then you can do myDecimal.HasValue

Use which one suits for your issue..

C#

decimal value = default(decimal); //0
        object objvalue = value; // object will be having 0

        decimal? nullableValue = null;  // null
        object objval = nullableValue.HasValue ? nullableValue.Value : default(decimal);

        decimal val = default(decimal);  //0
        decimal.TryParse(DBNull.Value.ToString(), out val); // if null it will be assigned as 0 , else the value
        object valueFromDataset = val;
