我需要从ForEachLinq 中调用函数，并且需要发送一个字符串参数和索引ForEach

List<string> listString= new List<string>();

listString.ForEach((str, i) => { Func(str, i) , i++});

private ResponseBase Func(string s,int i)
{

我想选择一个不在的列GROUP BY.

我的代码:

 SELECT 
     dbo.func(field1, field2), field3
 FROM
     table
 WHERE
     field4 = 1224
 GROUP BY
     dbo.func(field1, field2), field3
 HAVING
     COUNT(id) > 1

我想也选择这样的列id:

 SELECT 
     id, dbo.func(field1, field2), field3
 FROM
     table
 WHERE
     field4 = 1224
 GROUP BY
     dbo.func(field1, field2), field3
 HAVING
     COUNT(id) > 1
