How to get values for multiple InArgument

To get values for several InArguments, you need to understand how data moves and how variables work in your workflow. Staying organized and assigning each argument properly will help you avoid mistakes.

you’re working with Windows Workflow Foundation (WF), and you’ve built a custom activity that defines two InArgument properties: FText and LText.

You’re now trying to pass both arguments from XAML (for example, from a workflow .xaml file), but only one seems to get through.

Let’s fix that — and I’ll show you a complete working example.

1. Your custom activity class

Here’s a minimal version of your custom WF activity:

using System;
using System.Activities;

public class DisplayFullName : CodeActivity
{
    public InArgument FText { get; set; }
    public InArgument LText { get; set; }

    protected override void Execute(CodeActivityContext context)
    {
        // Get values passed from XAML or code
        string firstName = FText.Get(context);
        string lastName = LText.Get(context);

        Console.WriteLine($"Full Name: {firstName} {lastName}");
    }
}

2. Using it from XAML

Now, in your workflow XAML file, you can define and use this activity like this:

3. Passing values to it

If you want to hardcode values directly inside XAML:

This will print:

Full Name: John Doe

4. Passing variables defined in the workflow

If your workflow defines variables (say FirstName, LastName), you can bind them like so:

That syntax — FText="[FirstName]" — is very important: it binds the argument to the workflow variable.

6. If you’re invoking workflow from code

Here’s a quick example to run that .xaml and pass arguments at runtime:

using System;
using System.Activities;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        var inputs = new Dictionary
        {
            { "FText", "John" },
            { "LText", "Doe" }
        };

        WorkflowInvoker.Invoke(new DisplayFullName(), inputs);
    }
}

Summary

Define your custom activity with InArgument properties.
Use property.Get(context) to read values in Execute().
In XAML:

• Use property="LiteralValue" for constants.

• Use property="[VariableName]" for variables.
