MakeDynamic() public static method

Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder and two arguments.

public static MakeDynamic ( Type delegateType, CallSiteBinder binder, Expression arg0, Expression arg1 ) : DynamicExpression
delegateType	Type	The type of the delegate used by the .
binder	CallSiteBinder	The runtime binder for the dynamic operation.
arg0	Expression	The first argument to the dynamic operation.
arg1	Expression	The second argument to the dynamic operation.
return	DynamicExpression

        public static DynamicExpression MakeDynamic(Type delegateType, CallSiteBinder binder, Expression arg0, Expression arg1)
        {
            ContractUtils.RequiresNotNull(delegateType, nameof(delegateType));
            ContractUtils.RequiresNotNull(binder, nameof(binder));
            if (!delegateType.IsSubclassOf(typeof(MulticastDelegate))) throw Error.TypeMustBeDerivedFromSystemDelegate();

            var method = GetValidMethodForDynamic(delegateType);
            var parameters = method.GetParametersCached();

            ValidateArgumentCount(method, ExpressionType.Dynamic, 3, parameters);
            ValidateDynamicArgument(arg0, nameof(arg0));
            ValidateOneArgument(method, ExpressionType.Dynamic, arg0, parameters[1], nameof(delegateType), nameof(arg0));
            ValidateDynamicArgument(arg1, nameof(arg1));
            ValidateOneArgument(method, ExpressionType.Dynamic, arg1, parameters[2], nameof(delegateType), nameof(arg1));

            return DynamicExpression.Make(method.GetReturnType(), delegateType, binder, arg0, arg1);
        }
