CompilationStartAnalysisContext.TryGetValue Method

Definition

Namespace:

Microsoft.CodeAnalysis.Diagnostics

Assembly:

Microsoft.CodeAnalysis.dll

Package:

Microsoft.CodeAnalysis.Common v4.9.2

Overloads

TryGetValue<TValue>(AdditionalText, AdditionalTextValueProvider<TValue>, TValue)	Attempts to compute or get the cached value provided by the given valueProvider for the given text. Note that the pair {valueProvider, text} acts as the key. Reusing the same valueProvider instance across analyzer actions and/or analyzer instances can improve the overall analyzer performance by avoiding recomputation of the values.
TryGetValue<TValue>(SyntaxTree, SyntaxTreeValueProvider<TValue>, TValue)	Attempts to compute or get the cached value provided by the given valueProvider for the given tree. Note that the pair {valueProvider, tree} acts as the key. Reusing the same valueProvider instance across analyzer actions and/or analyzer instances can improve the overall analyzer performance by avoiding recomputation of the values.
TryGetValue<TValue>(SourceText, SourceTextValueProvider<TValue>, TValue)	Attempts to compute or get the cached value provided by the given valueProvider for the given text. Note that the pair {valueProvider, text} acts as the key. Reusing the same valueProvider instance across analyzer actions and/or analyzer instances can improve the overall analyzer performance by avoiding recomputation of the values.
