var user = db.t_ST_User
.Where(_user => string.Compare(domain, _user.domainName, StringComparison.OrdinalIgnoreCase) == 0)
.Where(_user => string.Compare(samAccountName, _user.samAccountName, StringComparison.OrdinalIgnoreCase) == 0)
.Where(_user => _user.deleted == false)
.FirstOrDefault();
上面的代码给我以下错误:
LINQ to Entities不支持指定的类型成员'domainName'。仅支持初始化程序,实体成员和实体导航属性。
但是domainName
是t_ST_User
的实体成员吗?
代码在迁移到新计算机之前可以正常工作,不确定是否相关。
public static int GetUserId(string domainName)
{
int nonExistingUserId = 0;
try
{
string message = "";
using (var db = new SurfaceTreatment.SurfaceTreatmentEntities())
{
string domain = domainName.Split('\\')[0].Trim();
string samAccountName = domainName.Split('\\')[1].Trim();
var user = db.t_ST_User
.Where(_user => string.Compare(domain, _user.domainName, StringComparison.OrdinalIgnoreCase) == 0)
.Where(_user => string.Compare(samAccountName, _user.samAccountName, StringComparison.OrdinalIgnoreCase) == 0)
.Where(_user => _user.deleted == false)
.FirstOrDefault();
if (user == null)
{
message = "Failed to get user by domain name: " + domainName;
LogHandler.LogDebug(logger, message);
return nonExistingUserId;
}
else
{
return user.userId;
}
}
}
catch (Exception ex)
{
LogHandler.LogError(logger, ex);
return nonExistingUserId;
}
}
public partial class t_ST_User
{
public int userId { get; set; }
public string badgeNumber { get; set; }
public string domainName { get; set; }
public string samAccountName { get; set; }
public string userName { get; set; }
public string userRemark { get; set; }
public System.DateTime createDate { get; set; }
public int createBy { get; set; }
public Nullable<System.DateTime> updateDate { get; set; }
public Nullable<int> updateBy { get; set; }
public bool deleted { get; set; }
public Nullable<System.DateTime> deleteDate { get; set; }
public Nullable<int> deleteBy { get; set; }
public string email { get; set; }
public bool confirmBeforeSubmitToApprover { get; set; }
public string preferredCompany { get; set; }
public string preferredDepartment { get; set; }
public string preferredPlant { get; set; }
public Nullable<int> preferredBuildingAddressId { get; set; }
}
创建表脚本:
CREATE TABLE [dbo].[t_ST_User](
[userId] [int] IDENTITY(1,1) NOT NULL,
[badgeNumber] [nvarchar](50) NOT NULL,

答案 0 :(得分:0)
从edmx中删除t_ST_User
,然后再次通过Update Model from Database
重新添加后,问题已解决。
