示例1: GetDiagnostic
internal async Task<IEnumerable<Diagnostic>> GetDiagnostic(SyntaxTree tree, DiagnosticDescriptor diagnosticDescriptor, CancellationToken cancellationToken)
{
try
{
// This can be called on a background thread. We are being asked whether a
// lightbulb should be shown for the given document, but we only know about the
// current state of the buffer. Compare the text to see if we should bail early.
// Even if the text is the same, the buffer may change on the UI thread during this
// method. If it does, we may give an incorrect response, but the diagnostics
// engine will know that the document changed and not display the lightbulb anyway.
if (Buffer.AsTextContainer().CurrentText != await tree.GetTextAsync(cancellationToken).ConfigureAwait(false))
{
return SpecializedCollections.EmptyEnumerable<Diagnostic>();
}
TrackingSession trackingSession;
if (CanInvokeRename(out trackingSession, waitForResult: true, cancellationToken: cancellationToken))
