Lambda Expression

用于简化匿名委托


this.form.Click += delegate(object sender, EventTags e) {
	// Handler action
};

// taken place by Lambda
this.form.Click += (object sender, EventTags e) => {
	// Handler action
};

闭包

lambda表达式内部可以访问外部的变量


int lamValue = 5;
Func<int,int> sum = x => x+lamValue;

本质是匿名函数
