C # can reduce or not use switch what method _ Practical Tips

The Insus.net solution is to use factory methods to process, create a factory interface, and then each method is designed as a factory class and implements the factory interface.
Factory Interface：

Copy Code code as follows:

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 ();
}
}

Get factory class：

Copy Code code as follows:

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 ';
}
}
}

Gettest class：

Copy Code code as follows:

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";
}
}
}

and Getset class：

Copy Code code as follows:

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";
}
}
}

so your code eventually becomes：

Copy Code code as follows:

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 (); Here is the implementation of the factory class
ret = Get. GetResult ();
return ret;
}
public string Get ()
//{
return ' get ';
//}
public string Gettest ()
//{
return "Gettest";
//}
public string Getrset ()
//{
return "Getset";
//}
}

15:50 modified to add the following：
The above final code, no incoming parameters mothedname, how to do, we can consider reflection, if the reverse shooting, the incoming parameters need to standardize the side can:
' Get ' >> ' get ';
"Get1" >> "Gettest"
"Testget" >> "Getset"
After such a change, you can use the reflection syntax, you can

Copy Code code as follows:

Igetfactory get = new Gettestfactory (); Here is the implementation of the factory class

Instead (the following is the application of asp.net):

Copy Code code as follows:

Igetfactory get = (igetfactory) assembly.load ("App_Code"). CreateInstance ("insus.net." + mothedname + "Factory");

If you are not asp.net, you can change "App_Code" to "assembly name":

Copy Code code as follows:

Igetfactory get = (igetfactory) assembly.load ("assembly name"). CreateInstance ("insus.net." + mothedname + "Factory");
