c# - 必须初始化隐式类型的局部变量

Question

这是代码:- 如何初始化数据？

var data;

if (mode == "view")
                {
                    data = (from a in ctx.tblEmployee
                            where a.CompanyId == companyId
                            join b in ctx.tblTO_ShiftSchedule on a.Id equals b.EmployeeId
                            where b.CompanyId == companyId                            
                            select new { a, b, c, d }).ToList();
                }
                else
                {
                    data = (from a in ctx.tblEmployee
                            where a.CompanyId == companyId                            
                            select new { a, b, c, d }).ToList();
                }

你不能初始化匿名类型，所以:

var data = mode == "view" 
? (from a in ctx.tblEmployee
                        where a.CompanyId == companyId
                        join b in ctx.tblTO_ShiftSchedule on a.Id equals b.EmployeeId
                        where b.CompanyId == companyId                            
                        select new { a, b, c, d }).ToList()
: (from a in ctx.tblEmployee
                        where a.CompanyId == companyId                            
                        select new { a, b, c, d }).ToList();
