C#可以减少或不使用switch有什么方法

复制代码 代码如下:

IGetFactory
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>
/// Summary description for IGetFactory
/// </summary>
namespace Insus.NET
{
public interface IGetFactory
{
string GetResult();
}
}

复制代码 代码如下:

GetFactory
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>
/// Summary description for GetFactory
/// </summary>
namespace Insus.NET
{
public class GetFactory : IGetFactory
{
public GetFactory()
{
//
// TODO: Add constructor logic here
//
}
public string GetResult()
{
return "get";
}
}
}

复制代码 代码如下:

GetTestFactory
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>
/// Summary description for GetTestFactory
/// </summary>
namespace Insus.NET
{
public class GetTestFactory : IGetFactory
{
public GetTestFactory()
{
//
// TODO: Add constructor logic here
//
}
public string GetResult()
{
return "gettest";
}
}
}

复制代码 代码如下:

GetSetFactory
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>
/// Summary description for GetSetFactory
/// </summary>
namespace Insus.NET
{
public class GetSetFactory : IGetFactory
{
public GetSetFactory()
{
//
// TODO: Add constructor logic here
//
}
public string GetResult()
{
return "getset";
}
}
}

复制代码 代码如下:

View Code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Insus.NET;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
public string Exec(string mothedName)
{
string ret = "";
//switch (mothedName)
//{
// case "get":
// ret = get();
// break;
// case "get1":
// ret = gettest();
// break;
// //.....
// case "testget":
// ret = getrset();
// break;
//}
IGetFactory get = new GetTestFactory(); //这里是实现工厂类
ret = get.GetResult();
return ret;
}
//public string get()
//{
// return "get";
//}
//public string gettest()
//{
// return "gettest";
//}
//public string getrset()
//{
// return "getset";
//}
}

复制代码 代码如下:

IGetFactory get = new GetTestFactory(); //这里是实现工厂类

复制代码 代码如下:

IGetFactory get = (IGetFactory)Assembly.Load("App_Code").CreateInstance("Insus.NET." + mothedName + "Factory");

复制代码 代码如下:

IGetFactory get = (IGetFactory)Assembly.Load("程序集名称").CreateInstance("Insus.NET." + mothedName + "Factory");
