在创建对象时读取匿名对象中的属性。 C＃

Question

Is there a way for me to read a property value I defined already in an anonymous object while creating the object?

here is an example

var a = new { PropA = "something", PropB = this.PropA + " and another thing"}

Answer 1

Perhaps defining it in a variable right before the declaration of a would work?

var somethingValue = "something";

var a = new { PropA = somethingValue , PropB = somethingValue  + " and another thing"}

Otherwise, I don't think you would be able to. You have yet to instantiate the object so this.PropA wouldn't work. To further elaborate, your question was " Is there a way for me to read a property value I defined already in an anonymous object while creating the object? " which doesn't entirely make sense, because you are creating the anonymous object, so the value isn't already defined in the object.

Answer 2

Using dynamic binding can be helpful:

dynamic myObject = a;
myObject.PropB  = ... //you can access any property that you know it exists
