C#之委托

直接上代码

javascript：

function get(url, success) {
    $.ajax({
        type: "Get",
        url: url,
        data: {},
        contentType: "application/json",
        dataType: "json",
        success: success || function (res) { },
        error: function () {
            alert("ajax error");
        }
    });
}

//调用
get("/api/sample", function (res) {
    console.log(res);
});

//使用箭头函数简化
get("/api/sample", (res) => {
    console.log(res);
});

C#

public static void Get(string url, Action<string> success)
{
    WebClient client = new WebClient();
    string result = client.DownloadString(url);
    success(result);
}

//调用
Get("/api/sample", delegate (string res)
{
    Console.WriteLine(res);
});

//使用lambda表达式简化
Get("/api/sample", (res)=>{
    Console.WriteLine(res);
});

结论

还要说总结什么吗？
