示例1: EvaluateUnaryOperation
private static object EvaluateUnaryOperation(object argument, Func<Expression, Expression> expressionBuilderMethod, Type resultType)
{
string cacheKey = expressionBuilderMethod.Method().Name + "_" + resultType.Name;
Func<object, object> lambda;
lock (unaryDelegateCache)
{
if (!unaryDelegateCache.TryGetValue(cacheKey, out lambda))
{
lambda = GetUnaryEvaluationDelegate(expressionBuilderMethod, resultType);
unaryDelegateCache.Add(cacheKey, lambda);
}
}
argument = ChangeType(argument, resultType);
return lambda(argument);
}示例2: EvaluateBinaryOperation
