TryEvaluate(IMemory, Options)
Evaluate the expression.
public (object value, string error) TryEvaluate (AdaptiveExpressions.Memory.IMemory state, AdaptiveExpressions.Options options = default);member this.TryEvaluate : AdaptiveExpressions.Memory.IMemory * AdaptiveExpressions.Options -> ValueTuple<obj, string>Public Function TryEvaluate (state As IMemory, Optional options As Options = Nothing) As ValueTuple(Of Object, String)Parameters
- state
- IMemory
Global state to evaluate accessor expressions against. Can be IDictionary<TKey,TValue>, IDictionary otherwise reflection is used to access property and then indexer.
- options
- Options
Options used in the evaluation.
Returns
Computed value and an error string. If the string is non-null, then there was an evaluation error.
Applies to
TryEvaluate(Object, Options)
Evaluate the expression.

- state
- Object
Global state to evaluate accessor expressions against. Can be IDictionary<TKey,TValue>, IDictionary otherwise reflection is used to access property and then indexer.
- options
- Options

Applies to
TryEvaluate<T>(IMemory, Options)
Evaluate the expression.
