C# List集合 where的用法

 

1、單個條件

   //Name是傳入的參數值
   List<Test> list = new List<Test>();
   list = list.Where(a => a.testName.Contains(Name)).ToList();

2、多個條件合並查詢

  //Number_Name是傳入的參數值
  List<Test> list = new List<Test>();
  list = list.Where(a => a.testNumber.Contains(Number_Name) || a.testName.Contains(Number_Name)).ToList();
  //

  List<Test> list = new List<Test>();
  list = list.Where(a => a.testNumber.Contains(Number_Name) && a.testName.Contains(Number_Name)).ToList();
