{Dynamics CRM 365} Implement Locking mechanism using C#

While working on one of the requirement where we needed to generate unique ID for the Custom Entity record. We thought of using plugin code to implement Auto number generate unique ID. However when multiple records were getting created from integrations and various sources, many duplicated IDs were getting generated.

After invetsigating further and multiple search on internet, we finally decided to use lock mechanism which is provided by .net framewrok.

C# Code to Generate ID using lock 

Class Helper
{
private static object lockObj = new object();

public static string GenerateId()
{
lock (Helper.lockObj)
{
Thread.Sleep(100);
string empty = string.Empty;
DateTime now = DateTime.Now;
string str1 = now.Year.ToString((IFormatProvider)CultureInfo.InvariantCulture);
now = DateTime.Now;
int month = now.Month;
string str2 = month < 10 ? "0" + month.ToString() : month.ToString();
now = DateTime.Now;
int day = now.Day;
string str3 = day < 10 ? "0" + day.ToString() : day.ToString();
now = DateTime.Now;
int hour = now.Hour;
string str4 = hour < 10 ? "0" + hour.ToString() : hour.ToString();
now = DateTime.Now;
int minute = now.Minute;
string str5 = minute < 10 ? "0" + minute.ToString() : minute.ToString();
now = DateTime.Now;
int second = now.Second;
string str6 = second < 10 ? "0" + second.ToString() : second.ToString();
now = DateTime.Now;
int millisecond = now.Millisecond;
string str7 = millisecond < 10 ? "0" + millisecond.ToString().Substring(0, 1) : millisecond.ToString().Substring(0, 1);
int num = new Random().Next(100, 999);
return empty + str1 + str2 + str3 + str4 + str5 + str6 + str7 + num.ToString();
}
}
}

Lock

C# Lock keyword ensures that one thread is executing a piece of code at one time. The lock keyword ensures that one thread does not enter a critical section of code while another thread is in that critical section.

Lock is a keyword shortcut for acquiring a lock for the piece of code for only one thread.

Hope this helps!
