如何在我的linqued查询变量中动态存储所需的值 [英] how to store dynamically the desired value in my linqued query variable

问题描述

我有这个查询

  var empno = (from LApp in db.Employees
                    select new { LApp.EmployeeNumber }).ToList();

执行时，我在empno中拥有这个

when executed I have this in empno

我想要的是修剪起始零并将其存储在empno中

what I want is to trim the starting zeros and store it in empno

即{EmployeeNumber ="2"}，依此类推... 怎么可能?

i.e {EmployeeNumber="2"} and so on... How is it possible?

推荐答案

您可以使用

You can use TrimStart() to remove leading zeros, something like this :

var empno = (from LApp in db.Employees
             select new { EmployeeNumber = LApp.EmployeeNumber.TrimStart('0') }
            ).ToList();

我不知道是否可以将TrimStart()转换为SQL，如果原来不支持TrimStart()，则可能需要AsEnumerable().

I have no idea if TrimStart() can be translated to SQL, you might need AsEnumerable() if TrimStart() turned out not supported.
