示例1: GetOutsideTypeQualifiedName
private string GetOutsideTypeQualifiedName(SyntaxNode node)
{
// Get the name space name enclosing this node.
string namespaceName = node.AncestorsAndSelf().
// ancestors whose kind is name space node.
Where(n => n.Kind == SyntaxKind.NamespaceDeclaration).
// conver to the syntax and get the name.
Select(n => (NamespaceDeclarationSyntax)n).First().Name.PlainName;
// Get the class name enclosing this node.
var classesNames = node.AncestorsAndSelf().
// ancestors whose kind is class node.
Where(n => n.Kind == SyntaxKind.ClassDeclaration).
// convert each one to the kind class node syntax.
Select(n => (ClassDeclarationSyntax)n).
// order all the class decs by their length, in decending order.
OrderByDescending(n => n.Span.Length).
// select their names.
Select(n => n.Identifier.ValueText);
// Combine all the names to get the scope string.
var qualifiedName = namespaceName + "." + StringUtil.ConcatenateAll(".", classesNames);
logger.Info(qualifiedName);
return qualifiedName;
