Array查询数组中是否包含指定字符

arrStrFilterColumn 为string[] 类型

if (!Array.Exists(arrStrFilterColumn, a =>
                            {
                                return a.Equals(dt.Columns[j].Caption.Trim(),
                                                StringComparison.OrdinalIgnoreCase);
                            }))

｛代码。。。。。。。。。。

//List<EmployeeWorkTypeStatisticsModel>  employeeWorkTypeStatistics =...;

   var listAddress = (from a in employeeWorkTypeStatistics
                               group a by new { a.EmployeeType, a.WorkType } into g
                               select new EmployeeWorkTypeStatisticsModel
                               {
                                   EmployeeType = g.Key.EmployeeType,
                                   WorkType = g.Key.WorkType,
                                   EmployeeCount = g.Sum(c => c.EmployeeCount)
                               }).OrderBy(t => t.EmployeeType);
