MakeDynamic() public static method

Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder and one argument.

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

        public static DynamicExpression MakeDynamic(Type delegateType, CallSiteBinder binder, Expression arg0)
        {
            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, 2, parameters);
            ValidateDynamicArgument(arg0, nameof(arg0));
            ValidateOneArgument(method, ExpressionType.Dynamic, arg0, parameters[1], nameof(delegateType), nameof(arg0));

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