Copy

 
using System;

namespace HelloWorld
{
   class Hello
   {
     
	 static void Main()
      {
	 
	   Console.WriteLine("Hello World");
    }
  }
}

4. On the Actions list, click Advanced and then click C# from the Programming list. The Action Builder window for C# displays.
5. Select File from the Method drop-down list.
6. Click the Folder () in the File field, navigate to your Desktop, and select the Notepad file called csharpexample.txt you created in step 3. Select Open to save the cshartexample.txt file location to the File field.
7. Select the Save to check box to activate the Save to field and select the Output variable from the Save to drop-down list.
8. Set the Run Switch to Don't Run.
9. Click OK to add the C# action to the botflow.
10. Click Play () at the bottom of the Nintex RPA LE window to run the botflow.

The words "Hello World" display in the Output variable Value field.

The C# action comes with a feature used to set a variable's Value field.

Use the function "RPAEngine.SetVar" with the syntax : RPAEngine.SetVar("RPA_Variable_Name", CS_Value)

To create the C# action using the RPAEngine.SetVar function:

1. If not already running, start Nintex RPA LE.
2. Create a variable called Output.
   1. Click Add Item () on the Botflow Pane.
   2. Click Variable. The Variable window displays.
   3. Type Output in the Name field.
   4. Click OK to save the variable.
3. Create three variables called Variable1, Variable2, and Variable3.
1. Click Add Item () on the Botflow Pane.
2. Click Variable. The Variable window displays.
3. Type Variable1 in the Name field.
4. Select Number in the Type field drop-down list.
5. Click OK to save the variable.
6. Repeat steps a through e to create variables named Variable2 and Variable3.
4. On the Actions list, click Advanced and then click C# from the Programming list. The Action Builder window for C# displays.
5. Select Code from the Method drop-down list.
6. Click the Copy link below, and copy and paste the C# code from the window that appears into the Code field.
Copy

 
using System;
namespace Program
{
    class Calculation
    {
      static void Main()
      {
      Int32 x = 1, y = 2;
      RPAEngine.SetVar("Variable1", x);
      RPAEngine.SetVar("Variable2", y);
      RPAEngine.SetVar("Variable3", x + y);
      Console.WriteLine("SUCCESS");
    }
  }
}

7. Select the Save to check box to activate the Save to field and select the Output variable from the Save to drop-down list.
8. Set the Run Switch to Don't Run.
9. Click OK to add the C# action to the botflow.
10. Click Play () at the bottom of the Nintex RPA LE window to run the botflow.

The number "1" displays in the Variable1 variable Value field. The number "2" displays in the Variable2 variable Value field. The number "3" displays in the Variable3 variable Value field. The word "SUCCESS" displays in the Output variable Value field.

The C# action comes with a feature used to:

• Get a variable's Value field value.
• Set another variable's Value field with that value.

Use the function "RPAEngine.GetVar" with the syntax : RPAEngine.GetVar("RPA_Variable_Name", CS_Value)

To create the C# action using the RPAEngine.GetVar function:

1. If not already running, start Nintex RPA LE.
2. Create two variables called Variable1 and Variable2.
1. Click Add Item () on the Botflow Pane.
2. Click Variable. The Variable window displays.
3. Type Variable1 in the Name field.
4. Select Number in the Type field drop-down list.
5. Type "1111" in the Value field.
6. Click OK to save the variable.
7. Repeat steps a through f to create a variable named Variable2, leaving the Value field blank.
3. On the Actions list, click Advanced and then click C# from the Programming list. The Action Builder window for C# displays.
4. Select Code from the Method drop-down list.
5. Click the Copy link below, and copy and paste the C# code from the window that appears into the Code field.
Copy

 
using System;
namespace Program
{
    class Test
    {
      static void Main()
      {
      String strValue = "0";
      RPAEngine.GetVar("Variable1", strValue);
      RPAEngine.SetVar("Variable2", strValue);
    }
  }
}

6. Set the Run Switch to Don't Run.
7. Click OK to add the C# action to the botflow.
8. Click Play () at the bottom of the Nintex RPA LE window to run the botflow.

The number "1111" is copied from the Variable1 variable Value field and pasted into the Variable2 variable Value field.

The C# action comes with a feature used to load a dll.

Use the function "RPAEngine.LoadDLL" with the syntax : RPAEngine.LoadDLL("Path")

To create the C# action using the RPAEngine.LoadDLL function:

1. If not already running, start Nintex RPA LE.
2. On the Actions list, click Advanced and then click C# from the Programming list. The Action Builder window for C# displays.
3. Select Code from the Method drop-down list.
4. Click the Copy link below, and copy and paste the C# code from the window that appears into the Code field.
Copy

 
RPAEngine.LoadDLL("System.Windows.Forms.dll")

using System.Windows.Forms;

namespace HelloWorld
{
    class Hello
    {
        static void Main()
        {

           MessageBox.Show("Hello World");
        }
    }
}

5. Set the Run Switch to Don't Run.
6. Click OK to add the C# action to the botflow.
7. Click Play () at the bottom of the Nintex RPA LE window to run the botflow.

A message window displays "Hello World."
