我有以下设置:

public class Child<T>: BaseClass
{
    public T Value;
}

public class IntChild: Child<int> { }

public class BoolChild: Child<bool> { }

public class MyProgram
{
    public BaseClass Source;

    public void SetValue(object val)
    {
        // I want to do something like the following

        switch (Source.GetType())  
        {
            case "IntChild":
                ((IntChild) Source).Value = int.Parse(val.ToString());
                break;
            case "BoolChild": …
