C# CRM编码逻辑错误
这实际上与特定错误无关；我的代码没有做它应该做的事情 我有一个代码块（foreach循环），它初始化另一个类中的方法（“getCustomerByGuid（）”）。此方法应将一个项目客户集合（CRM中的列表）添加到另一个客户集合。循环时，它应使用所有~2500个值填充客户集合 问题是，循环完成后，customer集合中只填充了一个customer—列表中要添加到集合中的最后一个customer。我试过几种不同的方法，但没有成功。。因为MS CRM只显示集合中的一个客户（即营销列表，它是活动的一部分，等等） 这是我的密码。让我知道你的想法。谢谢 这是正在运行的主Program.cs代码：C# CRM编码逻辑错误,c#,logic,dynamics-crm,crm,C#,Logic,Dynamics Crm,Crm,这实际上与特定错误无关；我的代码没有做它应该做的事情 我有一个代码块（foreach循环），它初始化另一个类中的方法（“getCustomerByGuid（）”）。此方法应将一个项目客户集合（CRM中的列表）添加到另一个客户集合。循环时，它应使用所有~2500个值填充客户集合 问题是，循环完成后，customer集合中只填充了一个customer—列表中要添加到集合中的最后一个customer。我试过几种不同的方法，但没有成功。。因为MS CRM只显示集合中的一个客户（即营销列表，它是活动的一部

for（int i=0；i谢谢…您在
getCustomerByGuid（）this.Clear（），即在每次调用该方法时（即在循环的每次迭代中）删除所有客户。然后，该方法中的最后一行this.AddRange
，但这只会添加当前客户
我认为这个.Clear（）doCRMWork
中，code>应该在foreach（guids中的字符串）前面。。。可能是这样。Clear（）。不知道为什么我到现在才注意到。我会测试它，让你知道会发生什么。。。罗拉：就是这样。。我在发布这篇文章后不久就注意到了。哦。。。谢谢
