I have some LINQ code that generates a list of strings, like this:

var data = from a in someOtherList
           orderby a
           select FunctionThatReturnsS

Depending on how the JIT optimizes it, either string.Concat() or Marc's method with StringBuilder could be faster. Since you're using Linq here, I'll assume performance isn't the absolute #1 requirement, in which case I'd go with the easiest to read:

string.Concat(data.ToArray());


Edit: if and only if data is IEnumerable of a value type, you'll need to cast it to an IEnumerable
