I am trying to convert database results into a dictionary of type Property name, property value.

IEnumerable<image> results = Entity.GetAllContent<image>();

Dictionary<string, object> dict =
            results.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public).ToDictionary(
                prop => prop.Name, prop => prop.GetValue(results, null));

The line Entity.GetAllConent is just an overload for ormlite select. Normally this would return a generic list of multiple objects ( image ). However when I try to do the above code, its like it is trying to convert a list or IEnumerable to a dictionary, rather than converting the base type.

I get the following exception:

Parameter count mismatch.

Dynamics CRM 2011 Set Quotes Revision Number

I am tasked with importing data from a CRM 3.0 instance into a CRM 2011 instance via the service layer. I've completed most of the entities but I hit a snag with Quotes. Revising a Quote creates a copy of the Quote and then increment its Revision Number. Revision Number is a read only field in the 2011 Service Layer. This creates a serious problem as you can imagine. Is there some other way to set this?

Update There is a ReviseQuoteRequest that will allow you to create a new revision of the Quote. The only problem with this is that I am trying to keep the same Guids when importing Entities. You can set the Guid to assign when you create a new Quote, but I don't see a way to tell the ReviseQuoteRequest what Guid to use when creating the Quote Revision and I don't believe the API allows you to Update this ID once its set. Any thoughts on how I can accomplish this?

我不确定这将如何工作。您有一个相同类型对象的列表 ( image)。每一个都将具有相同的属性（可能是 Id、Name 等）。你怎么把它们都放在一本字典里？每个人都有重复的密钥。您需要重写它以创建一个字典列表，每个元素 1 个。

var dictionaries = results.Select(x => x.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public)
                          .ToDictionary(prop => prop.Name, prop => prop.GetValue(x, null)))
                          .ToList();
