Question

Can the compiler/runtime reorder or inline expression trees?

If I got the following code:

public static int SomeSimpleMethod(int x) {
    return x;
}

void Main() {
    Expression<Func<bool>> expr = () => SomeSimpleMethod(2) == 3;
}

Can expr then include something else than (in pseudo code)

Expression.Lambda
    Expression.Equals
         Expression.Call
             Expression.Constant
         Expression.Constant

Edit

I am just parsing the expression tree to find some items like the name of the method call (“SomeSimpleMethod”). The lambda will never be executed so I just want to ensure that the method call is not optimized away from the expression tree.

Answer 1

The compiler will never optimize that.
