如何在linq查询中使用contains？ [英] How to use contain in linq query?

问题描述

我希望能够查询（name）参数，例如（api / data？name = prestl，accam，bcam ...（25个值）。这是我现在拥有的并且代码抛弃了我以下问题：



委托'System.Func< Testing_Apr.database_Bd，int，bool>'不带1个参数



字符串'不包含'split'的定义，也没有扩展方法'split'接受类型'的第一个参数可以找到字符串'（你是否错过了使用指令或汇编引用？）

I would like to be able to query the (name) parameter such as (api/data?name=prestl,accam,bcam...(25 values). This is currently what I have and the code is throwing me the following issues:

Delegate 'System.Func<Testing_Apr.database_Bd,int,bool>' does not take 1 arguments

string' does not contain a definition for 'split' and no extension method 'split' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)

var data = db.database_Bd.AsQueryable();

            if (query.startDate != null)
            {
                data = data.Where(c => c.UploadDate >= query.startDate);
            }

            if (!string.IsNullOrEmpty(query.name))
            {
                var list = query.name.split(',');
                data = data.Where(pr => list.Any(pr2 => pr.Name.Contains(pr2)));
            }

任何建议都非常感谢。

非常感谢

Any advice, would be very much appreciated.
Many thanks

推荐答案

C＃区分大小写：split与Split不一样



尝试：

C# is case sensitive: "split" is not the same as "Split"

Try:

var list = query.name.Split(',');
