Here’s an example of how the “Assign” activity works –

In the following example, I will calculate the total cost of items based on the quantity, utilizing the “Assign” activity. Here I have created three variables such as “ItemPrice, Quantity, and Total cost” with “Int32” as datatype for all three.

Example

1. Create a new solution or open an existing solution.
2. The “Primitives” features will be installed by default during the installation of the “Designer”.
3. Drag and drop the “Assign” activity to the workflow and set it as start node.
a. In the first assign, I am entering the “To” as “ItemPrice” and “Value” as “32”.
4. Now, I am adding another “Assign” activity below to the first one to assign values to the “Quantity” variable.
a. Providing the value as “4”.
5. Then, adding the final “Assign” activity to calculate the values and assign to “TotalCost” variable.
a. To perform the action, I am providing the value as “32*4” in the box.
6.You can add the “Writelog” activity to view the results.
7. Now, execute the workflow.
