Methods

ParseLambda(Boolean, ParameterExpression[], Type, String, Object[])

Parses an expression into a LambdaExpression.

Declaration

[PublicAPI]
public static LambdaExpression ParseLambda(bool createParameterCtor, [NotNull] ParameterExpression[] parameters, [CanBeNull] Type resultType, [NotNull] string expression, params object[] values)
