原來寫介面只用了本機快取cache

來學習一下radis，用法應該跟cache一樣吧，為了配套負載均衡的多伺服器是多個伺服器都可以讀取快取

一、下載

找了好長時間

github有的時候能上有的時候就上不去

等了一會可以訪問了就給下載下來了

分享一下：

綠色版連結：綠色版下載連結　　提取碼：bz04

msi版連結：安裝包版下載連結　　提取碼：7lu6

二、安裝

我原來安裝過。

綠色版：待補充

msi安裝包：很簡單一直Next就行

三、使用

C#  呼叫

在查詢相關文件時發現有

stackExchange.Radis 和 ServiceStack.Redis兩種引用檔案

查閱文件時發現統一說ServiceStack.Redis這個是要收費的每小時限制6000次讀寫，stackExchange.Radis則免費

文件：

關於c＃：StackExchange.Redis和ServiceStack.Redis之間的區別

C#教程之ServiceStack.Redis 和 StackExchange.Redis 效能比

Redis中ServiceStack.Redis和StackExchange.Redis區別是什麼

C# ServiceStack.Redis和StackExchange.Redis 使用心得

『效能』ServiceStack.Redis 和 StackExchange.Redis 效能比較

Redis中ServiceStack.Redis和StackExchange.Redis區別詳解

眼見為實寫了一個Demo測試一下：

每小時確實有讀寫限制提示內容：

ServiceStack.LicenseException:“The free-quota limit on '6000 Redis requests per hour' has been reached. Please see https://servicestack.net to upgrade to a commercial license or visit https://github.com/ServiceStackV3/ServiceStackV3 to revert back to the free ServiceStack v3.”

四、總結

StackExchange.Redis：

ServiceStack.Redis：每小時6000條限制，但是操作比StackExchange.Redis好用。

附上測試程式碼：

using Newtonsoft.Json;
using ServiceStack.Redis;
using StackExchange.Redis;
using System;
using System.Diagnostics;
using System.Threading;
using System.Windows.Forms;

            Thread thread = new Thread(ServiceStackRedis);
            Thread thread1 = new Thread(StackExchangeRedis);

            thread1.Start();
        }

                database1.StringSet("StackExchangeRedis", resultStr);
            }
            stopwatch.Stop();
            TimeSpan timeSpan = stopwatch.Elapsed;
            label3.Text = Convert.ToString(timeSpan.TotalSeconds);
        }

        private void ServiceStackRedis()
        {
            RedisClient client = new RedisClient("127.0.0.1", 6379);       //本機IP,Redis預設埠是6379
            Stopwatch stopwatch = new Stopwatch();
            stopwatch.Start();
            for (int i = 0; i < 10000; i++)
            {
                Class1 model = client.Get<Class1>("ServiceStackRedis");
                if (model == null)
                {
                    model = new Class1() { name = "張三",age = i};
                }
                else
                {
                    model.age = i;
                }
                client.Set<object>("ServiceStackRedis", model);
            }
            stopwatch.Stop();
            TimeSpan timeSpan = stopwatch.Elapsed;
