本文实例为大家分享了C#实现Nginx平滑加权轮询算法的具体代码，供大家参考，具体内容如下

代码很简单，算法很经典！

1. 定义实体类

public struct ServerConfig { //初始权重 public int Weight {get;set;} //当前权重 public int Current {get;set;} //服务名称 public string Name {get;set;} }

2. 算法

public static int NextServerIndex(ServerConfig[] serverConfigArray) { int index = -1; int total = 0; int size = serverConfigArray.Count(); for(int i = 0; i< size; i++) { serverConfigArray[i].Current += serverConfigArray[i].Weight; total += serverConfigArray[i].Weight; if (index == -1 || serverConfigArray[index].Current < serverConfigArray[i].Current) { index = i; } } serverConfigArray[index].Current -= total; return index; }

3.调用

static void Main(string[] args) { var sv = new ServerConfig[] { new ServerConfig{Name="A", Weight = 4}, new ServerConfig{Name="B", Weight = 2}, new ServerConfig{Name="C", Weight = 1} }; int index = 0; int sum = sv.Sum(m => m.Weight); for(int i=0; i<sum; i++) { index = NextServerIndex(sv); Console.WriteLine("{0}{1}", sv[index].Name, sv[index].Weight); } Console.Read(); }
