示例1: DetermineNewDocumentAsync
private async Task<Document> DetermineNewDocumentAsync(MemberInsertionCompletionItem completionItem, ITextSnapshot textSnapshot, CancellationToken cancellationToken)
{
// The span we're going to replace
var line = textSnapshot.GetLineFromLineNumber(completionItem.Line);
var sourceText = textSnapshot.AsText();
var document = sourceText.GetOpenDocumentInCurrentContextWithChanges();
Contract.ThrowIfNull(document);
// Annotate the line we care about so we can find it after adding usings
var tree = document.GetSyntaxTreeAsync(cancellationToken).WaitAndGetResult(cancellationToken);
var token = GetToken(completionItem, tree, cancellationToken);
var annotatedRoot = tree.GetRoot(cancellationToken).ReplaceToken(token, token.WithAdditionalAnnotations(_otherAnnotation));
document = document.WithSyntaxRoot(annotatedRoot);
var memberContainingDocument = await GenerateMemberAndUsingsAsync(document, completionItem, line, cancellationToken).ConfigureAwait(false);
var insertionRoot = PrepareTreeForMemberInsertion(memberContainingDocument, cancellationToken);
var insertionText = GenerateInsertionText(memberContainingDocument, cancellationToken);
var destinationSpan = ComputeDestinationSpan(insertionRoot, insertionText);
var finalText = insertionRoot.GetText(sourceText.Encoding).Replace(destinationSpan, insertionText.Trim());
document = document.WithText(finalText);
var newRoot = document.GetSyntaxRootAsync(cancellationToken).WaitAndGetResult(cancellationToken);
var declaration = GetSyntax(newRoot.FindToken(destinationSpan.End));
document = document.WithSyntaxRoot(newRoot.ReplaceNode(declaration, declaration.WithAdditionalAnnotations(_annotation)));
return Formatter.FormatAsync(document, _annotation, cancellationToken: cancellationToken).WaitAndGetResult(cancellationToken);
