使用TimeSpan保存在数据库中时发生此错误... !!!
error: An exception of type 'System.Data.Entity.Infrastructure.DbUpdateException' occurred in EntityFramework.dll but was not handled in user code.
this error occurred when using TimeSpan for saving in database...!!!
var db = new Online_GameEntities();
TimeSpan ts = new TimeSpan(0, 0, 0);
DateTime dtnow = DateTime.Now;
int h = dtnow.Hour;
int m = dtnow.Minute;
int s = dtnow.Second;
int day = dtnow.Day;
TimeSpan tsnow = new TimeSpan(day, h, m, s);
TimeSpan tscreate = new TimeSpan(0, 12, 25);
TimeSpan tscreated = tsnow.Add(tscreate);
tbl_building insertbuild = new tbl_building();
insertbuild.createdtime = (TimeSpan)tscreated;
insertbuild.createtime = (TimeSpan)tscreate;
insertbuild.levels = 1;
insertbuild.c_id = "ttyuyt";
insertbuild.firststate = true;
insertbuild.name = "";
insertbuild.x =5;
insertbuild.y = 5;
insertbuild.image = "b1.jpg" + "_" + 5;
db.tbl_building.Add(insertbuild);
db.SaveChanges();
推荐答案
SQL中没有适合TimeSpan的数据类型...
从您提交的文件名中我得出结论,您有DATETIME SQL数据类型 - 在C#代码中也使用相同的数据...
There is no such data type in SQL that fits TimeSpan...
From the names of your filed I conclude that you have DATETIME SQL data type - use the same for your data in your C# code too...
