dynamics-crm-2011 - 如何将 CRM 4 类型更改为 CRM 2011

Question

我正在尝试将 crm 4 插件转换为 CRM 2011。有谁知道 CRm 2011 中的相应类型是什么？

Customer, CrmDateTime, CrmDecimal, CrmFloat, CBoolean, CrmMoney, Owner, Picklist, Key, Status, UniqueIdentifier, CrmBoolean

public static object GetAttributeValue(this Entity target, string attributeLogicalName)
        {
            object value;
            if (target.Attributes.Contains(attributeLogicalName))
            {
                value = target.Attributes[attributeLogicalName];
                if ((value is Boolean) || (value is string))
                    return value;
                else if (value is Customer)
                    return ((Customer)value).Value;
                else if (value is CrmDateTime)
                    return ((CrmDateTime)value).UserTime;
                else if (value is CrmDecimal)
                    return ((CrmDecimal)value).Value;
                else if (value is CrmFloat)
                    return ((CrmFloat)value).Value;
                else if (value is CrmNumber)
                    return ((CrmNumber)value).Value;
                else if (value is CBoolean)
                    return ((CrmBoolean)value).Value;
                else if (value is Lookup)
                    return ((Lookup)value).Value;
                else if (value is CrmMoney)
                    return ((CrmMoney)value).Value;
                else if (value is Owner)
                    return ((Owner)value).Value;
                else if (value is Picklist)
                    return ((Picklist)value).Value;
                else if (value is Key)
                    return ((Key)value).Value;
                else if (value is Status)
                    return ((Status)value).Value;
                else if (value is UniqueIdentifier)
                    return ((UniqueIdentifier)value).Value;
                else if (value is CrmBoolean)
                    return ((CrmBoolean)value).Value;
                return null;
            }
            else
                return null;
        }

自 Dynamics CRM 2011 起，不再需要自定义类型来替代 .NET 类型。您可以(并且必须)使用标准的 .NET 类型。参见 Types in the Microsoft Dynamics CRM SDK类型映射的描述。

CRM 3 和 CRM 4 中存在自定义类型(CrmBoolean，...)是必要的，因为 CRM 3 基于 .NET 1，其中没有可空类型。
