bool test = true;
// This expression represents the conditional block.
Expression ifThenElseExpr = Expression.IfThenElse(
Expression.Constant(test),
Expression.Call(
null,
typeof(Console).GetMethod("WriteLine", new Type[] { typeof(String) }),
Expression.Constant("The condition is true.")
),
Expression.Call(
null,
typeof(Console).GetMethod("WriteLine", new Type[] { typeof(String) }),
Expression.Constant("The condition is false.")
)
);
// The following statement first creates an expression tree,
// then compiles it, and then runs it.
Expression.Lambda<Action>(ifThenElseExpr).Compile()();
输出:
The condition is true.
