Using C# inline on Maps in BizTalk


In this article, I will cover how to implement custom business logic (a simple string concatenation) using C# inline on maps in BizTalk. This is a common scenario when the business logic is very simple and we want to embed the logic within the map.

Getting started with the solution

First of all, open Visual Studio .NET and create an empty solution. Then add an Empty Biztalk Server project (see Figure 1).

Figure 1

Now let's create two schemas which are the basis of the transformation. The first one represents the input parameters (see Figure 2) and the other one represents the output parameter (see Figure 3).

Now let's add a map representing the concatenation transformation. Set the source and destination schemas. Click on the Toolbox window, and then click on the Advanced Functoids tab, and drag and drop the Scripting functoid onto the map surface. This functoid's input and output values are dependent of the logic contained within the Scripting functoid. Connect the left side of Scripting functoid to the appropriate source data items as well as the right side to the destination data items (see Figure 4).

Now let's configure the Scripting functoid by right-click over it and selecting Configure Functoid Script option (see Figure 5).


Figure 5

When the Configure Functoid Script dialog is displayed, select Inline C# for Script Type. Then enter the business logic written in C# in the Inline script buffer textbox (see Figure 6).

In this article, I covered how to embed inline C# code in the map in order to implement business logic related to the transformation. Now you can apply this solution to your business scenario.
