示例1: LeaveReturnStatement
public override void LeaveReturnStatement(ReturnStatement node)
{
if (null == node.Expression)
return;
// forces anonymous types to be correctly
// instantiated
IType expressionType = GetConcreteExpressionType(node.Expression);
if (TypeSystemServices.VoidType == expressionType
&& node.ContainsAnnotation(OptionalReturnStatementAnnotation))
{
node.ParentNode.Replace(
node,
new ExpressionStatement(node.Expression));
return;
}
IType returnType = _currentMethod.ReturnType;
if (TypeSystemServices.IsUnknown(returnType))
_currentMethod.AddReturnExpression(node.Expression);
else
AssertTypeCompatibility(node.Expression, returnType, expressionType);
//bind to nullable Value if needed
if (TypeSystemServices.IsNullable(expressionType) && !TypeSystemServices.IsNullable(returnType))
{
// TODO: move to later steps or introduce an implicit conversion operator
var mre = new MemberReferenceExpression(node.Expression.LexicalInfo, node.Expression, "Value");
Visit(mre);
node.Replace(node.Expression, mre);
