JIT 编译器遇到内部限制。 C#、VS 2019
JIT Compiler encountered an internal limitation. C#, VS 2019
我开始学习 C# 并想出了这个异常：
System.InvalidProgramException
HResult=0x8013153A
Message=JIT Compiler encountered an internal limitation.
Source=<Cannot evaluate the exception source>
StackTrace:
<Cannot evaluate the exception stack trace>
当我尝试使用传入 DateTime 参数的存储过程从数据库中获取数据时，会发生此异常。
这是我得到的完整信息：
<Error>

代码如下
这部分是调用存储过程并传递参数：
public class FiveDaysEventsData
{
public List <FiveDaysEventsModel> getFiveDaysEvents()
{
SqlDataAccess sql = new SqlDataAccess();
//stuff for testing:
DateTime date = new DateTime(2019, 11, 10);
var output = sql.LoadData<FiveDaysEventsModel, DateTime>("dbo.spGetDatePlusFiveDaysEvents", date, "MFData");
return output;
}
}
这是 sql 连接和数据加载的部分（使用 Dapper）：
internal class SqlDataAccess
{
public string GetConnectionString(string name)
{
return ConfigurationManager.ConnectionStrings[name].ConnectionString;
}
public List<T> LoadData<T, U>(string storedProcedure, U parameters, string connectionStringName)
{
string connectionString = GetConnectionString(connectionStringName);
using (IDbConnection connection = new SqlConnection (connectionString))
{
List<T> rows = connection.Query<T>(storedProcedure, parameters,
commandType: CommandType.StoredProcedure).ToList();
return rows;
}
}
}
这是我要获取的商品型号：
public class FiveDaysEventsModel
{
public DateTime Event_Date { get; set; }
public string CompanyName { get; set; }
public string Booked_for { get; set; }
public TimeSpan Time_From { get; set; }
public TimeSpan Time_To { get; set; }
public string LocationName { get; set; }
public string ContactName { get; set; }
public string PhoneNumber { get; set; }
public string EventStatus { get; set; }
public int EventID { get; set; }
}
这是一个存储过程：
CREATE PROCEDURE [dbo].[spGetDatePlusFiveDaysEvents]
@EventDate Datetime2
AS
BEGIN
set nocount on;
SELECT
ed.Event_Date, c.[Name] as CompanyName, ed.Booked_for,
ed.Time_From, ed.Time_To, loc.[Name] as LocationName, cnt.[Name] as ContactName,
cnt.PhoneNumber, ed.[Status] as EventStatus, ed.ID as EventID
FROM
dbo.[EventData] ed,
dbo.Company c,
dbo.Contact cnt,
dbo.[Location] loc
WHERE
(ed.Event_Date>= @EventDate and ed.Event_Date<= DATEADD(day, 5, @EventDate)) and
c.ID = ed.Company_ID and ed.ContactID = cnt.ID;
End
更新 1:
如果我使用没有参数和 LINQ 输出的 SP - 它一切正常：
var output = sql.LoadData<FiveDaysEventsModel, dynamic>("dbo.spEvents_GetAll", new { }, "MFData");
//instead of
var output = sql.LoadData<FiveDaysEventsModel, DateTime>("dbo.spGetDatePlusFiveDaysEvents", date, "MFData");
和
return output.Where(o => (o.Event_Date >= DateTime.Today && o.Event_Date <= DateTime.Today.AddDays(5))).ToList();
//instead of
return output;
使用 SP：
CREATE PROCEDURE [dbo].[spEvents_GetAll]
AS
BEGIN
set nocount on;
SELECT
ed.Event_Date, c.[Name] as CompanyName, ed.Booked_for, ed.Time_From, ed.Time_To, loc.[Name] as LocationName, cnt.[Name] as ContactName,
cnt.PhoneNumber, ed.[Status] as [Status], ed.ID
FROM
dbo.[EventData] ed,
dbo.Company c,
dbo.Contact cnt,
dbo.[Location] loc
WHERE
ed.Company_ID = c.ID and
ed.ContactID = cnt.ID and
ed.LocationID = loc.ID
END
但我不想每次都加载整个 table...
我想 DateTime 转换有问题，任何想法 reg。去哪里看？
与其将 DateTime 作为参数传入，不如将其作为动态对象的一部分传入，如下所示：
var output = sql.LoadData<FiveDaysEventsModel, dynamic>("dbo.spGetDatePlusFiveDaysEvents", new { EventDate = date }, "MFData");
您遇到的问题是因为 Dapper 需要某种类型的参数集。它可以采用的集合类型相当宽松，包括列表和对象。但是，像 DateTime 这样的结构会导致它出现问题。不要单独传递一个对象，而是将它作为匿名 class 对象的一部分传递，就像我所做的那样，其中 属性 名称对应于存储过程中的参数，你会没事的。
