为什么我会得到“集合初始化程序的最佳重载List<DelegationInformation>添加方法有一些无效的参数”

Question

我想返回delInfo变量及其内部的数据。但我不明白到底出了什么问题？

我收到错误了

集合初始化器的最佳重载列表添加方法有一些无效的参数

这是我的密码：

public List<DelegationInformation> GetDelegations(string profileUid, List<int> userPrivilegeIds)
{
    using (var context = GetDBContext())
    {
        var delInfo =
            (
                from delegation in context.vw_Delegations
                where delegation.Delegator == profileUid && userPrivilegeIds.Contains(delegation.AccessPrivilegeID)
                select new DelegationInformation()
                {
                    id = delegation.DelegationID,
                    DelegationId = delegation.DelegationID,
                    AccessPrivilegeId = delegation.AccessPrivilegeID,
                    AccessPrivilegeKey = delegation.AccessPrivilegeKey,
                    AccessPrivilegeName = delegation.AccessPrivilegeName,
                    Enabled = delegation.Status,
                    IsPermanent = delegation.isPermanent.HasValue ? delegation.isPermanent.Value : false,
                    Delegatee = delegation.Delegatee,
                    DelegateeFirstName = delegation.DelegateeFirstName,
                    DelegateeLastName = delegation.DelegateeLastName,
                    Delegator = delegation.Delegator,
                    DelegatorFirstName = delegation.DelegatorFirstName,
                    DelegatorLastName = delegation.DelegatorLastName,
                    StartDate = delegation.StartDate,
                    EndDate = delegation.EndDate,
                    ChangedBy = delegation.ChangedBy,
                    ChangedOn = delegation.ChangedOn,
                }
            ).ToList();

        foreach (var item in delInfo)
        {
            item.DelegateeFullName = ARMCommon.GetProfileDisplayName(item.Delegatee);
            item.DelegatorFullName = ARMCommon.GetProfileDisplayName(item.Delegator);
        }

        return new List<DelegationInformation>
        {
           delInfo
        };
    }
}

Answer 1

返回应该是

return delInfo;

Answer 2

只要返回delInfo，因为它已经是列表了

return delInfo;
