Question

帮助！我把下面的代码放在LINQ-TO-SQL中。请注意，我在WHERE子句中只使用了一个字段，但LINQ在多个字段中将SELECT与WHERE组合在一起。我制作了一个PROFILE并捕获了组装好的SELECT。你能帮我强迫LINQ只在指定的字段中搜索吗？我正在使用数据库优先。

我的LINQ代码：

var query = from v in ctx.cliente
                            orderby v.razao_social
                            where v.fantasia.ToLower().Contains(pesquisa) 
                            select new
                            {
                                id_cliente = v.id_cliente,
                                razao = v.razao_social,
                                fantasia = v.fantasia,
                                cnpj = v.cnpj,
                                cidade = v.cidade.cidade1 + "/" + v.cidade.uf1,
                                fone = v.fone1
                            };

现在，我来自探查者的结果：

    [Project1].[id_cliente] AS [id_cliente], 
    [Project1].[razao_social] AS [razao_social],

C＃ - LINQ使用错误的WHERE子句挂载SELECT
