问题描述
.Net 中是否为 C# 定义了一个默认方法来删除列表中所有 null 的元素?
Is there a default method defined in .Net for C# to remove all the elements within a list which are null?
List<EmailParameterClass> parameterList = new List<EmailParameterClass>{param1, param2, param3...};
假设一些参数是null;我无法提前知道,我想从我的列表中删除它们,以便它只包含不为空的参数.
Let's say some of the parameters are null; I cannot know in advance and I want to remove them from my list so that it only contains parameters which are not null.
