Blue Prism - Issue with setting parameters using C#

VarindaS_ — Wed, 03 Jan 2024 13:14:22 GMT

Hello,

I am working on a code stage in Blue Prism using C#. I am passing one number data item "UserCapacity" and three collections and getting Result as an output.

For the "UserCapacity", I tried following approaches.

int userCapacity = Convert.ToInt32(GlobalContext.GetParameter("UserCapacity")); //this did not work

int userCapacity = Convert.ToInt32("UserCapacity"); //this worked

For collection, I am trying to set the collection "ExistingTasks" as Lists. I am facing issue with GlobalContext. I have tried using BluePrism.Interop.GlobalContext but it won't work.

List<Dictionary<string, object>> existingTasksData = (List<Dictionary<string, object>>)GlobalContext.GetParameter("ExistingTasks");

If I set it like below, I get error, "Cannot convert type 'System.Data.DataTable' to 'System.Collections.Generic.List<System.Collections.Generic.Dictionary<string, object>>"

List<Dictionary<string, object>> existingTasksData = (List<Dictionary<string, object>>) ExistingTasks;

Please let me know what can I do to resolve this and how to set parameters correctly. I have attached the images for input, output, code, references and namespaces.

Hi varinda,

You already defined UserCapacity data item as a number in input parameter

if you want to pass that in the code stage then you can do some thing like below
int userCapacity = Convert.ToInt32(UserCapacity)
You can try with out quotes since UserCapacity is defined as input parameter.

Hi Harish,

I can do it for number variable.

However, for collection, I cannot convert type from DataType to List. Hence, the issue.

List<Dictionary<string, object>> existingTasksData = (List<Dictionary<string, object>>)GlobalContext.GetParameter("ExistingTasks");
