Invoking Code Source File
linkUse this workflow to invoke a coded source file within a
low-code workflow. In this example, we create a class called
TimeSpanHelper
in the TimeSpanHelper.cs
coded
source file. This class generates a random time span based on the specified bounds. To
integrate this class in a low-code workflow, we use an Invoke Workflow File
activity, followed by other low-code activities, depending on the use case.
-
Create a coded source file. For this example, name it
TimeSpanHelper.cs
. -
In the coded source file, create a public class named
TimeSpanHelper.
-
Inside the TimeSpanHelper class, declare a private static
Random object named
_random
to generate random values.private static Random _random = new Random();
private static Random _random = new Random(); -
Declare a private static object named
_lockObj
to secure the thread, while working with multiple threads at the same time..private static object _lockObj = new object();
private static object _lockObj = new object(); -
Implement a public static method called
GetRandomTimeSpanBetween
that takes two integer parameters:lowerBoundMs
andupperBoundMs
.public static TimeSpan GetRandomTimeSpanBetween(int lowerBoundMs, int upperBoundMs) {
public static TimeSpan GetRandomTimeSpanBetween(int lowerBoundMs, int upperBoundMs) { -
Use the lock statement with
_lockObj
to secure this thread, while working with multiple threads at the same time.lock (_lockObj) {
lock (_lockObj) { -
Within the lock block, generate a random integer value using
_random.Next
and passlowerBoundMs
andupperBoundMs
as the arguments.var ms = _random.Next(lowerBoundMs, upperBoundMs);
var ms = _random.Next(lowerBoundMs, upperBoundMs); -
Convert the generated random value to a
TimeSpan
object usingTimeSpan.FromMilliseconds
and return this value directly from the method with the following command return:return TimeSpan.FromMilliseconds(ms);
return TimeSpan.FromMilliseconds(ms);
Based on these steps, your final code should look like this:public class TimeSpanHelper { private static Random _random = new Random(); private static object _lockObj = new object(); public static TimeSpan GetRandomTimeSpanBetween(int lowerBoundMs, int upperBoundMs) { lock (_lockObj) { var ms = _random.Next(lowerBoundMs, upperBoundMs); return TimeSpan.FromMilliseconds(ms); } } }
public class TimeSpanHelper { private static Random _random = new Random(); private static object _lockObj = new object(); public static TimeSpan GetRandomTimeSpanBetween(int lowerBoundMs, int upperBoundMs) { lock (_lockObj) { var ms = _random.Next(lowerBoundMs, upperBoundMs); return TimeSpan.FromMilliseconds(ms); } } } -
Inside the TimeSpanHelper class, declare a private static
Random object named
-
Create a low-code workflow. For this example, name it
WorkflowUsingCodeSourceFile
. - Add a Log Message activity to output a random timespan between two and four seconds.
-
In the Message field, type the name of the project, call the coded
source file, and then call the
GetRandomTimeSpanBetween
method.In the example below,CodedWorkflowInteroperability
is the name of the project.CodedWorkflowInteroperability.TimeSpanHelper.GetRandomTimeSpanBetween(2000, 4000)
CodedWorkflowInteroperability.TimeSpanHelper.GetRandomTimeSpanBetween(2000, 4000)
