Script

The Script activity allows you to execute C# code within your workflow to perform calculations, manipulate data, or create workflow variables.

Purpose​

Use the Script activity to:

  • Create or update workflow variables
  • Perform calculations or data transformations
  • Execute custom logic that doesn't require conditional branching
  • Set values that will be used in subsequent workflow steps

Configuration​

Script Activity Editor

Code Expression​

  • Write C# code that performs an action
  • Can create new workflow variables or update existing ones
  • Code is executed at runtime

Single Exit Path​

  • Unlike the If activity, Script has only one outcome path
  • Execution always continues to the next connected activity

Example Scripts​

Creating a Date Variable​

{Year} = DateTime.Now.Year

Creates a workflow variable called "Year" with the current year

Using Parameter References​

{ProcessDate} = DateTime.Now

Calculations​

{Total} = {Quantity} * {Price}

Variable Syntax​

  • Create/Update Variable: {VariableName} = value
  • Reference Variable: {VariableName}
  • Variables persist throughout the workflow execution
  • Variable names are case-sensitive

Usage Notes​

  • Not for Regular Users: This activity requires C# programming knowledge
  • Advanced Use Cases: Primarily used when standard activities don't meet specific needs
  • Variables Scope: Variables created are available to all subsequent activities in the workflow
  • Type Safety: All variables are evaluated and typed at runtime
  • You can use any C# expression that produces a value
  • Variables can be shortened names or shortcuts to longer parameter references

Common Patterns​

Date Extraction​

{CurrentYear} = DateTime.Now.Year
{CurrentMonth} = DateTime.Now.Month

Variable Shortcuts​

{Year} = {FinancialYearParameter}

Create a shorter variable name for easier reference

String Manipulation​

{FullName} = {FirstName} + " " + {LastName}

When to Use​

  • When you need to create intermediate values for later use
  • When standard activities don't provide the specific transformation you need
  • When you want to simplify complex parameter references
  • For advanced workflow developers only
