C#中累加器函数Aggregate用法实例

var shouldExclude = false;var dirName = dir.Name;foreach(var pattern in excludePatterns){  shouldExclude = shouldExclude || Regex.Match(dirName, pattern).Success;}// 使用Aggregate改写var dirName = dir.Name;var shouldExclude = excludePatterns.Aggregate(false, (current, pattern) => current || Regex.Match(dirName, pattern).Success);
