How to use ForEach Actvity in Workflow designer to read list item values from customer activity

[jayachandra21]

Hi,

I have a custom activity named it as CustomActivity1 and it returns the list as below screenshow.

I have set list in SetVariable as,

**Output.SetVariable("FetchJSONVal", _strOutput);**'

Moreover, I want to use ForEach Acitivity in workflow designer to loop the above list items and check in each iteration if(EmpData.Value>EmpData.ID) then send an email

How to design it and what is the best possible approach?

Thanks for your support
CustomActivity1.cs

` [ActivityProperty(Hint = "Enter an Expression that evaluates to the name of the database connection string.")]
public WorkflowExpression ConnectionString
{
get => GetState<WorkflowExpression>();
set => SetState(value);
}
protected override async Task OnExecuteAsync(WorkflowExecutionContext context, CancellationToken cancellationToken)
{
try
{
var sqlconnectionString = await context.EvaluateAsync(ConnectionString, cancellationToken);
List _strOutput = await FetchDataAsync(sqlconnectionString, cancellationToken);
Output.SetVariable("FetchJSONVal", _strOutput);
}
catch (Exception ex)
{
throw ex;
}
return Done();
}
private Task<List> FetchDataAsync(string _connectionstring, CancellationToken cancellationToken)

    {
        List<EmpData> geo = new List<EmpData> {
                new EmpData { Name="Emp1",Value="100", ID=1,Unit="1"},
                new EmpData { Name="Emp2",Value="101", ID=2,Unit="2"},
                new EmpData { Name="Emp3",Value="102", ID=3,Unit="3"},
            };
        return Task.FromResult(geo);
    }

    public class EmpData
    {
        public string Name { get; set; }
        public string Value { get; set; }
        public int ID { get; set; }
        public string Unit { get; set; }

    }
