ExpressionEvaluator 构造函数

定义

命名空间:

AdaptiveExpressions

程序集:

AdaptiveExpressions.dll

包:

AdaptiveExpressions v4.22.7

初始化 ExpressionEvaluator 类的新实例。

public ExpressionEvaluator (string type, AdaptiveExpressions.EvaluateExpressionDelegate evaluator, AdaptiveExpressions.ReturnType returnType = AdaptiveExpressions.ReturnType.Object, AdaptiveExpressions.ValidateExpressionDelegate validator = default);

new AdaptiveExpressions.ExpressionEvaluator : string * AdaptiveExpressions.EvaluateExpressionDelegate * AdaptiveExpressions.ReturnType * AdaptiveExpressions.ValidateExpressionDelegate -> AdaptiveExpressions.ExpressionEvaluator

Public Sub New (type As String, evaluator As EvaluateExpressionDelegate, Optional returnType As ReturnType = AdaptiveExpressions.ReturnType.Object, Optional validator As ValidateExpressionDelegate = Nothing)

参数

type

String

表达式类型。

evaluator

EvaluateExpressionDelegate

委托以计算表达式。

returnType

ReturnType

应从评估中键入 。

validator

ValidateExpressionDelegate

表达式的静态验证。
