示例1: GetFormattingSpan
public static TextSpan GetFormattingSpan(SyntaxNode root, TextSpan span)
{
Contract.ThrowIfNull(root);
var startToken = root.FindToken(span.Start).GetPreviousToken();
var endToken = root.FindTokenFromEnd(span.End).GetNextToken();
var startPosition = startToken.SpanStart;
var endPosition = endToken.RawKind == 0 ? root.Span.End : endToken.Span.End;
return TextSpan.FromBounds(startPosition, endPosition);
}示例2: GetOwningNodes
/// <summary>
/// find owning usings/field/statement/expression-bodied member of the given position
/// </summary>
private static IEnumerable<SyntaxNode> GetOwningNodes(SyntaxNode root, int position)
{
// make sure caret position is somewhere we can find a token
var token = root.FindTokenFromEnd(position);
if (token.Kind() == SyntaxKind.None)
{
return SpecializedCollections.EmptyEnumerable<SyntaxNode>();
}
return token.GetAncestors<SyntaxNode>()
.Where(AllowedConstructs)

}示例3: GetTokens
private static void GetTokens(SyntaxNode root, TextSpan span, out SyntaxToken token1, out SyntaxToken token2)
{
// get tokens within given span
token1 = root.FindToken(span.Start);
token2 = root.FindTokenFromEnd(span.End);

// make tokens to be the adjacent ones to the given span.
