Bu cevap Entity Framework 6 ile çalışır
Kabul edilen yanıt, Öngörülen veya Anonim nesneler için çalışmaz. Performans da bir sorun olabilir.
Bunu başarmak için DbCommandInterceptor
EntityFramework tarafından sağlanan a , bir nesneyi kullanmamız gerekir .
Interceptor Oluşturun:
public class UtcInterceptor : DbCommandInterceptor
{
public override void ReaderExecuted(DbCommand command, DbCommandInterceptionContext<DbDataReader> interceptionContext)
{
base.ReaderExecuted(command, interceptionContext);
if (interceptionContext?.Result != null && !(interceptionContext.Result is UtcDbDataReader))
{
interceptionContext.Result = new UtcDbDataReader(interceptionContext.Result);
}
}
}
interceptionContext.Result
bizimki ile değiştirdiğimiz DbDataReader
public class UtcDbDataReader : DbDataReader
{
private readonly DbDataReader source;
public UtcDbDataReader(DbDataReader source)
{
this.source = source;
}
public override DateTime GetDateTime(int ordinal)
{
return DateTime.SpecifyKind(source.GetDateTime(ordinal), DateTimeKind.Utc);
}
public new void Dispose()
{
source.Dispose();
}
public new IDataReader GetData(int ordinal)
{
return source.GetData(ordinal);
}
}
Önleyiciyi cihazınıza kaydedin DbConfiguration
internal class MyDbConfiguration : DbConfiguration
{
protected internal MyDbConfiguration ()
{
AddInterceptor(new UtcInterceptor());
}
}
Son olarak, yapılandırmayı cihazınızda kaydedin. DbContext
[DbConfigurationType(typeof(MyDbConfiguration ))]
internal class MyDbContext : DbContext
{
}
Bu kadar. Şerefe.
