  A composite format string consists of zero or more runs of fixed text intermixed with one or more format items, which are indicated by an index number delimited with brackets (for example, `{0}`). The index of each format item corresponds to an argument in an object list that follows the composite format string. For example, in the following statement:  
   
  :::code language="csharp" source="~/snippets/csharp/System/FormattableString/Format/Composite1.cs" id="Snippet9":::
+ :::code language="fsharp" source="~/snippets/fsharp/System/FormattableString/Format/Composite1.fs" id="Snippet9":::
  :::code language="vb" source="~/snippets/visualbasic/VS_Snippets_CLR/Formatting.Composite/vb/Composite1.vb" id="Snippet9":::  
   
  the composite format string is `"Name = {0}, hours = {1:hh}"`.
