1 语法基本一样
两者都是C系语言。
2 对象构造：
2.1 javascript:
var obj = {Name:”sfeig”,Age:31};
2.2 C#:
var obj = new {Name=”sfeig”,Age=23};
3 数组：
3.1 javascript:
var arr = [1, 2, 3, 4, 5];
3.2 C#:
var arr = new [] {1,2,3,4,5};
4 匿名函数：
4.1 javascript:
var handler = function(sender,e){…};
4.2 C#:
var handler = delegate(object sender,EventArgs e){….};
5 扩展方法：
5.1 Javascript：
function Vector(x,y)
{
this.x = x;
this.y = y;
}
Vector.prototype.adds = function(v)
{
if(v instanceof Vector)
{
return new Vector(this.x+v.x, this.y + v.y);
}
else
{
alert("Invalid Vector object!");
}
}
var v = new Vector(1,2);
v = v.adds(v);
alert("x = " +v.x + ", y = "+v.y);
5.2 C#:
public class Vector
{
private double _x;
private double _y;
public double X
{
get { return this._x; }
set { this._x = value; }
}
public double Y
{
get { return this._y; }
set { this._y = value; }
}
}
public static class Extension
{
public static Vector Adds(this Vector p, Vector p1)
{
return new Vector { X = p.X + p1.X, Y = p.Y + p1.Y };
}
}
var v = new Vector { X = 1, Y = 2 };
v = v.Adds(v);
Console.WriteLine("v.X = {0} and v.Y = {1}", v.X, v.Y);
6 非null赋值：
6.1 C#中：
//string str = "hello";
string str = null;
this.Label1.Text = str ?? "china";
6.2 Javascript中：
var s0 = null;
//var s0 = "hello";
var s = s0 || "china";
alert(s);
