Foreach Write Headers and Footers Cleanly

I often have code that goes something like this.

StringBuilder sb = new StringBuilder();
IEnumerable<MyWidget> MyWidgets=GetMyWidgets();

if (MyWidgets.Count != 0)
{
    sb.Append("This is header text");

    foreach (MyWidget widget in MyWidgets)
    {
        sb.Append("This is info about widget: " + widget.SomeInfo);
    }

    sb.Append("This is footer text");
}

Is there some way to make this cleaner? Perhaps using lambda expressions or anonymous functions (I'm not familiar with those, so an example would be helpful)?

A real-world example is writing an HTML table if there are items present in the collection of objects.

Solution 
  • StringBuilder sb = new StringBuilder();
List<MyWidget> MyWidgets = GetMyWidgets().ToList();
if(MyWidgets.Count!=0)
{
    sb.Append("This is header text");
    MyWidgets.Foreach(w => sb.Append("This is info about widget: " + w.SomeInfo));
    sb.Append("This is footer text");
}
