I have the following object where in my constructor I add a new Guid as the Id.
public class MyObject
{
public MyObject()
{
Id = Guid.NewGuid().ToString();
}
public String Id { get; set; }
public String Test { get; set; }
}
I want to do something like that in an object initializer :
var obj = new MyObject
{
Test = Id; // Get new GUID created in constructor
}
Is it possible?
No, you can't do that. You'd have to just set it in a separate statement:
var obj = new MyObject();
obj.Test = obj.Id;
The right-hand side of the property in an object initializer is just a normal expression, with no inherent connection to the object being initialized.
If this is something you regularly want to do with one specific type, you could add a method:
public MyObject CopyIdToTest()
{
this.Test = Id;
return this;
}
and then use:
MyObject obj = new MyObject().CopyIdToTest();
or with other properties:
MyObject obj = new MyObject
{
// Set other properties here
}.CopyIdToTest();
No -- you can't access an object's properties inside an initializer. The initializer is basically some syntactic sugar for programmers.
Consider situations like:
class Program
{
static void Main()
{
var Id = "hello";
var obj = new MyObject
{
Test = Id // Get new GUID created in constructor
};
}
}
The Id you'd assign (if your idea was valid, which again, it isn't) isn't necessarily the Id you'd be getting.
