LINQ 方法语法与 where 子句

Question

我正在尝试将 LINQ 查询语法转换为方法语法，但它不起作用。

下面是我的查询语法

quotation = (from q in quotation 
             where q.IsQuotation  || !LineCodeUtility.IsNEWQuotation (q) 
             select q).ToList();

尝试转换为如下方法语法，但它不起作用

quotation = quotation.Where(x => x.IsNonNEWQuotation || x => !LineCodeUtility.IsNEWQuotation(x))
                     .ToList();

Answer 1

这些是等价的：

quotation =
(
    from q in quotation
    where q.IsQuotation || !LineCodeUtility.IsNEWQuotation(q)
    select q
).ToList();

quotation =
    quotation
        .Where(q => q.IsQuotation || !LineCodeUtility.IsNEWQuotation(q))
        .ToList();
