如何删除与条件匹配的所有列表行

我试图删除匹配where条件的List<T>中的所有记录。我在linq中发现的是RemoveAll()方法，但它似乎只能通过删除与条件匹配的属性而不是列表中的complete row来工作。

所以我确实尝试删除所有建议在这里与一个Where子句，导致"argument null exception".

问题:

如何使用linq删除所有匹配条件的列表行?

//Sort the list by the UpdatedTime time descending
//Remove all records in list that are older than today's date and status equal to BB. Then order the remaining records desc.
var cuttOff = DateTime.UtcNow.AddDays(-10);
List<Escalation> escHistorySorted = escHistory.RemoveAll.Where(x => x.UpdatedTime  <= cuttOff && x.status == "BB").OrderByDescending(d => d.UpdatedTime).ToList();

var cuttOff = DateTime.UtcNow.AddDays(-10);
escHistory.RemoveAll(x => x.UpdatedTime <= cuttOff && x.status == "BB");
List<Escalation> escHistorySorted = escHistory.OrderByDescending(d => d.UpdatedTime).ToList();
