c# - 对象初始化器和动态指定属性

Question

使用对象初始化器，是否可以选择性地包含属性设置？

例如:

Request request = new Request
{
    Property1 = something1,
    if(something)
        Property2 = someting2,                                      
    Property3 = something3
};

据我所知不是。很确定您唯一的选择是这样做:

Request request = new Request
{
    Property1 = something1,
    Property3 = something3
};
if(something)
    request.Property2 = someting2;

或者你可以这样做，如果有一个默认值/空值，你可以将它设置为:

Request request = new Request
{
    Property1 = something1,
    Property2 = something ? someting2 : null,
    Property3 = something3
};
