c# run thread in threadpool

This is the way of running thread in ThreadPool
1 only for 4.5 Framework

Task.Run(() => doStuff("hello world"));

Task.Factory.StartNew(() => doStuff("hello world"));

ThreadPool.QueueUserWorkItem(a => doStuff("hello world"));

void Example()
{
    // Hook up the ProcessFile method to the ThreadPool.
    // Note: 'a' is an argument name. Read more on arguments.
    ThreadPool.QueueUserWorkItem(new WaitCallback(ProcessFile), a);
}

private void ProcessFile(object a)
{
    // I was hooked up to the ThreadPool by WaitCallback.
}

EntityFramework exec proc with out params

using (var db = new MyEntities())
{
    var Owner_ID = new ObjectParameter("Owner_ID", typeof(string));
    var msgError = new ObjectParameter("msgError", typeof(string));
    db.InsBeerClient(Owner_ID, msgError);
    return (msgError.Value ?? "").ToString();
}

Entity Framework Update

You can easly do it by using this code

using (var db = new EGAIS_RUEntities())
            {
                db.Configuration.ValidateOnSaveEnabled = false;
                var _rec = new CONTRAGENT()
                {
                    id = 1,
                    status = 3
                };

                db.CONTRAGENTS.Attach(_rec);
                var entry = db.Entry(_rec);
                entry.Property(e => e.status).IsModified = true;
                db.SaveChanges();
            }

Please note, I set only value, that i wanted to cahnge. Another value is "id", that identifies the record.

Another interesting aspect is this

db.Configuration.ValidateOnSaveEnabled = false;

You will get an error if you don't set the fields with NOTNULL values.

another approach to it is

dbcontext.Entry(_rec).State = System.Data.Entity.EntityState.Modified;
dbcontext.SaveChanges();

с# get GOST 3410 certificate from container

public static X509Certificate2 GetCertFromCont(string pin, string CertCont)
        {
            CspParameters cspParameters = new CspParameters(75);
            cspParameters.KeyContainerName = CertCont;
            cspParameters.Flags = CspProviderFlags.NoPrompt;
 
 
 
            if (pin != "")
            {
                System.Security.SecureString s = new System.Security.SecureString();
                foreach (char z in pin)
                    s.AppendChar(z);
                cspParameters.KeyPassword = s;
            }

                    cspParameters);
                return prov.ContainerCertificate;
            }
            catch (Exception e)
            {
                //System.Windows.MessageBox.Show(e.Message);
                return null;
            }
 
        }
