如何合并EF实体集？

Question

I would like to obtain records from two sources (ie 2 different connection strings) with identical model to storage mappings.

Something more-or-less like:

var db = new MyModel(connectionString1);
var set1 = db.Things;
db = new MyModel(connectionString2);
set1.Merge(db.Things);

Is this possible?

Answer 1

Do you mean that you want all of the 'Things' from both DBs in 1 list? If so, you can just use the Union() method I believe:

Change the last line to:

var allThings = set1.Union(db.Things);
