示例1:
// Add the following directive to your file:
// using System.Linq.Expressions;
// This expression perfroms a logical AND operation
// on its two arguments, but if the first argument is false,
// then the second arument is not evaluated.
// Both arguments must be of the boolean type.
Expression andAlsoExpr = Expression.AndAlso(
Expression.Constant(false),
Expression.Constant(true)
);
// Print out the expression.
Console.WriteLine(andAlsoExpr.ToString());
// The following statement first creates an expression tree,
// then compiles it, and then executes it.
Console.WriteLine(Expression.Lambda<Func<bool>>(andAlsoExpr).Compile()());
输出:
(False AndAlso True) False
