public enum DbType
{
Mysql = 1,
Sqlserver = 2,
Pgsql = 3
}
public static class DbProviderFactory

public static IDbProvider CreateDbProvider(DbType dbType)
{
IDbProvider provider = null;
switch (dbType)
{
case DbType.Mysql:
provider = new MysqlDbProvider();
break;
case DbType.Pgsql:
provider = new PgsqlDbProvider();
break;
case DbType.Sqlserver:
provider = new SqlserverDbProvider();
break;
default:
break;

return provider;
}

工厂方法
发消息Provider。分别有email,sms,JiGuang Provider。

public interface IMessageProvider
{
void SendMessage(Guid userId, string message);
}
public abstract class AbsFactory
{
public abstract IMessageProvider CreateMessageProvider();
}
public class EmailFactory : AbsFactory
{
public override IMessageProvider CreateMessageProvider()
{
return new EmailMessageProvider();
}
}
public class EmailMessageProvider : IMessageProvider
{
public void SendMessage(Guid userId, string message)
{
Console.WriteLine($"邮件发送: {userId.ToString()} : {message}");
}
}
public class JiGuangFactory : AbsFactory
{
public override IMessageProvider CreateMessageProvider()
{
return new JiGuangMessageProvider();
}
}
public class JiGuangMessageProvider : IMessageProvider
{
public void SendMessage(Guid userId, string message)
{
Console.WriteLine($"极光发送：{userId.ToString()}:{message}");
}
}
public class SmsFactory : AbsFactory
{
public override IMessageProvider CreateMessageProvider()
{
return new SmsMessageProvider();
}
}
public class SmsMessageProvider : IMessageProvider
{
public void SendMessage(Guid userId, string message)
{
Console.WriteLine($"短信发送: {userId.ToString()} : {message}");
}
}
public class FactoryMethodMessageProviderUnitTest : AbsUnitTest
{
public override void Test()
{
while (true)
{
Console.WriteLine("请输入1|2|3");
int type = Convert.ToInt32(Console.ReadLine());
Guid userId = Guid.NewGuid();
string message = "你好";
switch (type)
{
case 1:
AbsFactory jiGuangFactory = new JiGuangFactory();
jiGuangFactory.CreateMessageProvider().SendMessage(userId, message);
break;
case 2:
AbsFactory smsFactory = new SmsFactory();
smsFactory.CreateMessageProvider().SendMessage(userId, message);
break;
case 3:
AbsFactory emailFactory = new EmailFactory();
emailFactory.CreateMessageProvider().SendMessage(userId, message);
break;
}
}
}
}
抽象方法
分app,h5两个工厂（还可以增加微信小程序工厂去统计微信小程序的相关行为） 工厂提供行为：给用户发消息，统计当前平台的用户数据

public abstract class AbsPlatformProviderFactory
{
public abstract IStatCalculate CreateStatCalculateProvider();
public abstract IPushMessage CreatePushMessageProvider();
}
public interface IStatCalculate
{
void CalcTodayData();
}
public interface IPushMessage
{
void PushMessage(Guid userId);
}
public class AppStatCalculate : IStatCalculate
{
public void CalcTodayData()
{
Console.WriteLine($"App:统计今日数据完成");
}
}
public class AppPushMessage : IPushMessage
{
public void PushMessage(Guid userId)
{
Console.WriteLine("App:发送消息完成" + userId.ToString());
}

string message = "你好";
switch (type)
{
case 1:
AbsPlatformProviderFactory h5PlatformProviderFactory = new H5PlatformProviderFactory();
h5PlatformProviderFactory.CreatePushMessageProvider().PushMessage(userId);
h5PlatformProviderFactory.CreateStatCalculateProvider().CalcTodayData();
break;
case 2:
AbsPlatformProviderFactory appPlatformProviderFactory = new AppPlatformProviderFactory();
appPlatformProviderFactory.CreatePushMessageProvider().PushMessage(userId);
appPlatformProviderFactory.CreateStatCalculateProvider().CalcTodayData();
break;
}
}
}
