Is there a way to have CodeDom put using statements before the namespace

Question

The msdn documentation says add namespaces imports to the CodeNamespace.Imports collection. This puts them inside the namespace (which makes sense, since your adding them to the namespace)

namespace Foo
{
  using Bar;

  //Code
}

However the rest of our code base has using statements outside the namespace:

using Bar;

namespace Foo
{
  //Code
}

Is there a clean way to get CodeDom to emit the second version?

Edit: the code to produce the first example looks something like this:

CodeNamespace ns = new CodeNamespace("Foo");
ns.Imports.Add(new CodenamespaceImport("Bar"));
CodeCompileUnit cu = new CodeCompileUnit();
cu.Namespaces.Add(ns);
new CSharpCodeProvider().GenerateCodeFromCompileUnit(cu, Console.Out, null);

The simplest way is to add a global namespace entry into the Compile Unit (namespace without a name) and add the imports to it.

So the code would be the same as before but with this bit added in.

CodeNamespace globalNamespace = new CodeNamespace();
globalNamespace.Imports.Add(new CodeNamespaceImport("Foo"));

// globalNamespace.Comments = string.Empty;    you cannot do this
ccu.Namespaces.Add(globalNamespace);
ccu.Namespaces.Add(ns);

the problem is that now I have an auto generated comment block at the beginning – Brian Apr 03 '11 at 19:30
