Det*_*ium 3 c# linq entity-framework
我正在尝试实现EF提供的分页功能.我想,我只需要添加的简单Skip()和Take()进入我的查询,但后来我得到这个消息:
错误4'System.Linq.IOrderedQueryable'不包含'Skip'的定义和最佳扩展方法重载'System.Linq.Queryable.Skip(System.Linq.IQueryable,int)'有一些无效的参数D:\ Biblioteker\HourRegistrationApplication\HourRegistrationService\HourRegistrationWCF\Service.cs 190 24 HourRegistrationWCF
我不太确定我需要做什么?我用谷歌搜索了一下,但没有找到任何有用的东西.
GetAllCustomers()
public List<CustomerDTO> GetAllCustomers(string take, string skip)
{
var custList = new List<CustomerDTO>();
var list = DAO.TDKanBanInstance.Customer.OrderBy(x => x.Name).Skip(skip).Take(take).ToList();
foreach (var cust in list)
{
custList.Add(new CustomerDTO()
{
Name = cust.Name
});
}
return custList;
}

工作解决方案
在take和skip需要是int当然的.
public List<CustomerDTO> GetAllCustomers(string take, string skip)
{
int skipInt = Int32.Parse(skip);
int takeInt = Int32.Parse(take);
var custList = new List<CustomerDTO>();
var list = DAO.TDKanBanInstance.Customer.OrderBy(x => x.Name).Skip(skipInt).Take(takeInt).ToList();
foreach (var cust in list)
{
custList.Add(new CustomerDTO()
{
Name = cust.Name
});
}
return custList;
}
