How to build a LINQ query from text at runtime?
- by Danvil
I have a
class A {
public int X;
public double Y;
public string Z;
// and more fields/properties ...
};
and a List<A> data and can build a linq query like e.g.
var q = from a in data where a.X > 20 select new {a.Y, a.Z};
Then dataGridView1.DataSource = q.ToList(); displays the selection in my DataGridView.
Now the question, is it possible to build the query from a text the user has entered at runtime? Like
var q = QueryFromText("from a in data where a.X > 20 select new {a.Y, a.Z}");
The point being, that the user (having programming skills) can dynamically and freely select the displayed data.
