Linq和String.Compare - 赋值的左侧必须是变量

Question

我正在尝试编写以下LINQ查询...

string userSearch = textBoxSearchUserInput.Text;
                //LINQ query for Member name search
                var MemberNameSearch =
                    from member in context.Members 
                    where String.Compare(userSearch, member.MemberLastName, true) = 0
                        select member;

但我在标题中收到错误消息。

我想要实现的目标，比较两个字符串而忽略大小写

由于

Answer 1

where String.Compare(userSearch, member.MemberLastName, true) == 0

要比较您需要使用==

Answer 2

这样可行

String.Equals(userSearch, member.MemberLastName, StringComparison.OrdinalIgnoreCase)

Answer 3

你应该改变它

where String.Compare(userSearch, member.MemberLastName, true) = 0

要

where String.Compare(userSearch, member.MemberLastName, true) == 0
