Contact.Update（...）EWS托管API的问题 [英] Problem with Contact.Update(...) EWS Managed API
问题描述
您好，我们目前正在自己的CRM软件和Exchange之间编写基于服务器的同步工具。几个月前，我已经完成了一项服务，将我们的SQLServer与Exchange的约会同步。它工作正常。现在我们想要从CRM同步联系人 - >交换。创建联系人没有问题（不包括"标题":)）。但是现在我对Contact对象的Update（...）方法有一点问题。
如果我看到联系人的数据发生了变化，我们将所有数据设置为新的并调用更新方法。但是在这里我得到了一个例外：变更描述中的对象必须包含一个且只有一个要修改的属性
但是...尝试不同的方式并跳转在我的代码中，我发现我们可以设置多个属性并调用Update（...）而不会出现异常。
例如：
Hello,
we are currently writing a server based synchronisation tool between our own CRM Software and Exchange. A few month ago I have completed a service to sync appointments from our SQLServer to Exchange. It works fine. Now we want to sync Contacts from CRM -> Exchange. Creating Contacts is no problem (excluding the "Title" :) ). But now I have a little problem with the Update( ... ) Method from the Contact object.
In the case that I see that data from a contact has changed, we set all data new and call the update method. But here i got a Exception that says: An object within a change description must contain one and only one property to modify
But... After trying out different ways and jumping around in my code, I discoverd that we can set more than one property and call Update( ... ) without getting a exception.
For Example:
If Not String.IsNullOrEmpty(company.InterNet) Then mContactperson.BusinessHomePage = company.InterNet
If Not String.IsNullOrEmpty(company.Telefon) Then mContactperson.PhoneNumbers(PhoneNumberKey.BusinessPhone) = company.Telefon
If Not String.IsNullOrEmpty(company.Telefon) Then mContactperson.PhoneNumbers(PhoneNumberKey.BusinessFax) = company.Telefax
更新（...）有效...
又
Update( ... ) works...
Also
' mContactperson is a 'Contact' object
If Not String.IsNullOrEmpty(company.InterNet) Then mContactperson.BusinessHomePage = company.InterNet
If Not String.IsNullOrEmpty(company.Telefon) Then mContactperson.PhoneNumbers(PhoneNumberKey.BusinessPhone) = company.Telefon
If Not String.IsNullOrEmpty(company.Telefon) Then mContactperson.PhoneNumbers(PhoneNumberKey.BusinessFax) = company.Telefax
Dim PHAdress As New PhysicalAddressEntry
If Not String.IsNullOrEmpty(company.Adresse.Ort) Then PHAdress.City = company.Adresse.Ort
If Not String.IsNullOrEmpty(company.Adresse.Staat) Then PHAdress.State = company.Adresse.Staat
If Not String.IsNullOrEmpty(company.Adresse.Plz) Then PHAdress.PostalCode = company.Adresse.Plz
mContactperson.PhysicalAddresses.Item(PhysicalAddressKey.Business) = PHAdress
更新（...）有效...
但是当我现在设置另一个像这样的物理地址...... br $> b $ b
Update( ... ) works...
But when I now set another physical adress like this...
' mContactperson is a 'Contact' object
If Not String.IsNullOrEmpty(company.InterNet) Then mContactperson.BusinessHomePage = company.InterNet
If Not String.IsNullOrEmpty(company.Telefon) Then mContactperson.PhoneNumbers(PhoneNumberKey.BusinessPhone) = company.Telefon
If Not String.IsNullOrEmpty(company.Telefon) Then mContactperson.PhoneNumbers(PhoneNumberKey.BusinessFax) = company.Telefax
Dim PHAdress As New PhysicalAddressEntry
If Not String.IsNullOrEmpty(company.Adresse.Ort) Then PHAdress.City = company.Adresse.Ort
If Not String.IsNullOrEmpty(company.Adresse.Staat) Then PHAdress.State = company.Adresse.Staat
If Not String.IsNullOrEmpty(company.Adresse.Plz) Then PHAdress.PostalCode = company.Adresse.Plz
mContactperson.PhysicalAddresses.Item(PhysicalAddressKey.Business) = PHAdress
Dim PrivatePHAddress As New PhysicalAddressEntry()
mContactperson.PhysicalAddresses.Item(PhysicalAddressKey.Home).Street = ap.Adresse.Straße
mContactperson.PhysicalAddresses.Item(PhysicalAddressKey.Home).City = ap.Adresse.Ort
mContactperson.PhysicalAddresses.Item(PhysicalAddressKey.Home).PostalCode = ap.Adresse.Plz
mContactperson.PhysicalAddresses.Item(PhysicalAddressKey.Home).State = ap.Adresse.Staat
Update抛出异常
所以看来编辑多个物理地址会导致问题。但是让我感到困惑的是，当我们在编辑两个物理地址之间调用Update（...）时，我也会遇到异常。这是更新联系人的错误方法吗？
Update throws the exception
So it seems editing more than one physical adress causes the problem. But what makes me real confusing is that I also get the exception when we call Update( ... ) between editing the two physical adresses. Is this the wrong way to update a contact?
