示例1:
// Add the following directive to your file:
// using System.Linq.Expressions;
int num = 100;
// This expression represents a conditional operation.
// It evaluates the test (first expression) and
// executes the iftrue block (second argument) if the test evaluates to true,
// or the iffalse block (third argument) if the test evaluates to false.
Expression conditionExpr = Expression.Condition(
Expression.Constant(num > 10),
Expression.Constant("num is greater than 10"),
Expression.Constant("num is smaller than 10")
);
// Print out the expression.
Console.WriteLine(conditionExpr.ToString());
// The following statement first creates an expression tree,
// then compiles it, and then executes it.
Console.WriteLine(
Expression.Lambda<Func<string>>(conditionExpr).Compile()());輸出：
IIF("True", "num is greater than 10", "num is smaller than 10")
num is greater than 10
