List of Records

Question

The following code seems to add a new record to the list but overwrites all the record with the last record created. I can get it to work fine with ...

lpr.Add(n         


        

Answer 1

pr is a reference to an object. When you change the values of pr you are changing the values of the same object and adding that reference to the list. So your list consists of several references to the same object, and the last values you set will be reflected by each reference.

You can solve it by adding

pr = new personRecord();

before each block to ensure that pr is referenceing a new object each time.

When you do

lpr.Add(new personRecord(){Age = pr.Age,Name = pr.Name});

You are adding a reference to a new object and just copying the values from the single pr reference.
