生成复杂参数类型的客户端代理

生成复杂参数类型的客户端代理
•使用GenerateScriptTypeAttribute标记要生成代理的参数类型
•可以标记在类、接口以及方法上
•生成的代理中将包括客户端类型的代理
•调用方法时可以创建“具体类型”
–new [Namespaces].ClassName()
–没有其他构造方法（构造函数）

aspx

    <form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server">
            <Services>
                <asp:ServiceReference Path="ColorService.asmx" InlineScript="true" />
            </Services>
        </asp:ScriptManager>
        
        <input type="button" value="Reverse Color" onclick="ReverseColor()" />
        
        <script language="javascript" type="text/javascript">
            function ReverseColor()
            {
                // var color = {"Red" : 50, "Green" : 100, "Blue" : 200};
                var color = new ComplexType.Color();
                color.Red = 50;
                color.Green = 100;
                color.Blue = 200;
                ColorService.Reverse(color, onSucceeded);
            }
            
            function onSucceeded(result)
            {
                alert(String.format(
                    "Red: {0}\nGreen: {1}\nBlue: {2}",
                    result.Red,
                    result.Green,
                    result.Blue));
            }
        </script>

ColorService.asmx

<%@ WebService Language="C#" Class="ColorService" %>

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Web.Script.Services;
using ComplexType;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class ColorService  : System.Web.Services.WebService
{
    [WebMethod]
    [GenerateScriptType(typeof(Color))]
    public Color Reverse(Color color)
    {
        return new Color(
            (byte)(255 - color.Red),
            (byte)(255 - color.Green),
            (byte)(255 - color.Blue));
    }
    
}

注意这里的ColorService类方法Reverse设置了[GenerateScriptType(typeof(Color))]标记要生成代理的参数类型，这样才可以使用Color作为参数的类型
