Most of us are comfortable with writing  just a few bunch of code lines in a C# TBB. Ever thought of writing functions in a C# TBB ? And wonder how to call these functions…

Let’s get Movin’…

1. Use the syntax <%!  %>  for defining functions inside the TBB.
2. You can define any number of functions as you like and call them.

<%@ Import Namespace="Tridion.ContentManager.ContentManagement.Fields"%>

string test ="Hello_From_C# TBB";
package.PushItem("Hello_C# TBB", package.CreateStringItem(ContentType.Text,test));

PushWelcomeMessageToPackage();
ProcessComponent();

<%! 

private void PushWelcomeMessageToPackage()
 {
   package.PushItem("Hello_From_Function_1", package.CreateStringItem(ContentType.Text,                                                                     "Got It"));
 }
  
private void ProcessComponent()
{
   Item compItem= package.GetByType(ContentType.Component);
   Component component = engine.GetObject(compItem.GetAsSource().GetValue("ID")) 
                         as Component;
ItemFields componentFields = new ItemFields(component.Content, component.Schema);

if (componentFields.Contains("BrandTitle"))
    { 
         TextField title= componentFields["BrandTitle"] as TextField; 
         package.PushItem("BrandTitle", package.CreateStringItem(ContentType.Text, 
                                                                 title.Value));
    }
}

%>

Run the Above TBB with any component and below are the results:
