Evaluate()

static object pluginbase.Helpers.Extensions.ExpressionExtensions.Evaluate ( this Expression  exp, bool  reflective = true  )

static

Evaluate the value of an expression

Parameters

exp	The expression
reflective	If set to true use reflective. Usually faster.

        {
            if (reflective)
            {
                return EvaluateReflective(exp);
            }
            return Expression.Lambda(exp).Compile().DynamicInvoke();
        }

ReduceMethodCall()

static CallableExpression pluginbase.Helpers.Extensions.ExpressionExtensions.ReduceMethodCall ( this LambdaExpression  exp )

static

Reduces a method call to its info, and values for arguments

Returns

The method call.

Parameters

exp

Exp.

Attribute: method.Arguments.Count

;

Attribute: i] = method.Arguments[i

.Evaluate();

        {
            var method = exp.Body as MethodCallExpression;
            if (method == null)
            {
                throw new InvalidOperationException("Expected expression to be callable");
            }

            var args = new object[method.Arguments.Count];
            for (int i=0; i<args.Length; ++i)
            {
                args[i] = method.Arguments[i].Evaluate();
            }

            return new CallableExpression
            {
                ArgumentValues = args,
                Method = method.Method,
                TargetType = EvaluateType(method.Object)
            };
        }
