从.net中的现有基础对象创建派生对象

public class BaseClass
{
    public string Property1 { get; set; }
    public void Method1()
    {
        // 方法实现
    }
}

public class DerivedClass : BaseClass
{
    public string Property2 { get; set; }
    public void Method2()
    {
        // 方法实现
    }
}

DerivedClass derivedObject = new DerivedClass();
derivedObject.Property1 = "Value1";
derivedObject.Property2 = "Value2";
derivedObject.Method1();
derivedObject.Method2();
