I have a Func like this :
Func<MyClass, bool> func = x=>Id == 5;
How I can convert it to :
Expression<Func<MyClass, bool>>
Try this:
Func<MyClass, bool> func = x=>Id == 5;
Expression<Func<MyClass, bool>> expr = mc => func(mc);
You can just write:
Expression<Func<MyClass,bool>> expr = x=>Id == 5;
This will set expr
to be an expression tree for Id == 5
.
If you do:
Func<MyClass, bool> func = x=>Id == 5;
Expression<Func<MyClass, bool>> expr = mc => func(mc);
Then this will set expr
to be an expression tree for a call to func
, not an expression tree for the body of func
.
