Gets the SyntaxTree for this document asynchronously.
public System.Threading.Tasks.Task<Microsoft.CodeAnalysis.SyntaxTree> GetSyntaxTreeAsync (System.Threading.CancellationToken cancellationToken = default);
public System.Threading.Tasks.Task<Microsoft.CodeAnalysis.SyntaxTree?> GetSyntaxTreeAsync (System.Threading.CancellationToken cancellationToken = default);
member this.GetSyntaxTreeAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.CodeAnalysis.SyntaxTree>
Public Function GetSyntaxTreeAsync (Optional cancellationToken As CancellationToken = Nothing) As Task(Of SyntaxTree)
Parameters
- cancellationToken
- CancellationToken
Returns
The returned syntax tree can be null
if the SupportsSyntaxTree returns false
. This function may cause computation to occur the first time it is called, but will return
a cached result every subsequent time. SyntaxTree's can hold onto their roots lazily. So calls
to GetRoot(CancellationToken) or GetRootAsync(CancellationToken) may end up causing computation
to occur at that point.
