使用EWS更新联系人

我一直在努力寻找如何与EWS合作，并设法找出如何做我想做的一切。我使用EWS来管理自定义数据库和Exchange服务器之间的联系（2007）。添加和删​​除工作正常，但我无法更新联系人。为了解决这个问题，我删除了联系人并重新创建了它，但是当通过Outlook（或其他任何东西）编辑联系人时会出现问题。

我试着按照这个链接说的那样：

http://msdn.microsoft.com/en-us/library/exchange/ee693002(v=exchg.80).aspx

但是我收到一条错误消息，说只能更新一个属性。然后我一次更新一个属性，一旦我尝试更新电话号码，我就会收到一条错误消息：“命名空间中的'更新'元素'http://schemas.microsoft.com/exchange/services / 2006 / types'内容不完整。“

这是代码，基本上是：

ItemId itemId = contactToUpdate.Id;
Contact updateContact = Contact.Bind(service, itemId);
updateContact.PhoneNumbers[PhoneNumberKey.HomePhone] = customContact.HomeTelephone;
updateContact.Update(ConflictResolutionMode.AlwaysOverwrite);

有谁知道我为什么会收到这个错误？任何人都可以回答如何实际更新项目？我有错过的文件吗？

EWS dll的版本是15.0.516.12。

经过多次调试后我找到了答案。我不会去探索更多以找出原因，但你不能这样做：

updateContact = Contact.Bind(service, itemId);
updateContact.PhoneNumbers[PhoneNumberKey.HomePhone] = customContact.HomePhone;
updateContact.PhoneNumbers[PhoneNumberKey.MobilePhone] = customContact.MobilePhone;
updateContact.PhoneNumbers[PhoneNumberKey.BusinessPhone] = customContact.BusinessPhone;
updateContact.Update(ConflictResolutionMode.AlwaysOverwrite);

但是，您可以只设置一个电话号码，然后在调试时更改其他两个的值（在断点处）。怪异。

无论如何，有一个问题 - 如果值没有改变（这就是答案），你就无法更新其中一个字典值，所以先检查一下这个值是否有所改变。接下来，如果值是空字符串，则需要将其另存为null。您还需要在尝试读取其值之前检查字典条目是否存在。

string number;
bool numberFound;

numberFound = updateContact.PhoneNumbers.TryGetValue(PhoneNumberKey.HomePhone, out number);
if ((numberFound && number != customContact.HomePhone) ||
    (!numberFound && !string.IsNullOrEmpty(customContact.HomePhone)))
{
    updateContact = Contact.Bind(service, itemId);
    updateContact.PhoneNumbers[PhoneNumberKey.HomePhone] = customContact.HomePhone == "" ? null : customContact.HomePhone;
    updateContact.Update(ConflictResolutionMode.AlwaysOverwrite);
}

更新地址：

updateContact = Contact.Bind(service, itemId);
updateContact.PhysicalAddresses[PhysicalAddressKey.Home].Street = customContact.Street == "" ? null : customContact.Street;
updateContact.PhysicalAddresses[PhysicalAddressKey.Home].State = customContact.Suburb == "" ? null : customContact.Suburb;
updateContact.PhysicalAddresses[PhysicalAddressKey.Home].City = customContact.City == "" ? null : customContact.City;
updateContact.PhysicalAddresses[PhysicalAddressKey.Home].CountryOrRegion = customContact.Country == "" ? null : customContact.Country;
updateContact.PhysicalAddresses[PhysicalAddressKey.Home].PostalCode = customContact.AreaCode == "" ? null : customContact.AreaCode;
updateContact.Update(ConflictResolutionMode.AlwaysOverwrite);

在我看来，这是API的粗心实施（以及糟糕的文档）。

需要对项目的每个属性执行更新的事实可能是由于服务器运行的是Exchange 2007，但这尚未得到确认。

我尝试使用相同结果的Microsoft.Exchange.WebServices版本14和15。

<强>更新

但等等，还有更多。

我发布了很多代码来说明如何更新不同的电话号码，地址等。该代码还显示了如何更新（或设置）标题，性别，后缀和自定义属性（用户定义的字段 - 如果要在Outlook中显示，则需要将用户定义的字段添加到contacts文件夹中。）

这是一段完整的，有效的代码：

Contact updateContact = Contact.Bind(service, itemId);
updateContact.GivenName = customContact.Name;
updateContact.Surname = customContact.Surname;

EmailAddress emailAddress;
bool emailAddressFound;

emailAddressFound = updateContact.EmailAddresses.TryGetValue(EmailAddressKey.EmailAddress1, out emailAddress);
if (emailAddressFound && emailAddress.Address != customContact.Email)
{
    emailAddress.Address = customContact.Email == "" ? null : customContact.Email;
}
else if (!emailAddressFound && !string.IsNullOrEmpty(customContact.Email))
{
    updateContact.EmailAddresses[EmailAddressKey.EmailAddress1] = customContact.Email;
}
updateContact.Initials = customContact.Initials;

string number;
bool numberFound;

numberFound = updateContact.PhoneNumbers.TryGetValue(PhoneNumberKey.HomePhone, out number);
if ((numberFound && number != customContact.HomePhone) || (!numberFound && !string.IsNullOrEmpty(customContact.HomePhone)))
{
    updateContact.PhoneNumbers[PhoneNumberKey.HomePhone] = customContact.HomePhone == "" ? null : customContact.HomePhone;
}
numberFound = updateContact.PhoneNumbers.TryGetValue(PhoneNumberKey.MobilePhone, out number);
if ((numberFound && number != customContact.CellPhone) || (!numberFound && !string.IsNullOrEmpty(customContact.CellPhone)))
{
    updateContact.PhoneNumbers[PhoneNumberKey.MobilePhone] = customContact.CellPhone == "" ? null : customContact.CellPhone;
}
numberFound = updateContact.PhoneNumbers.TryGetValue(PhoneNumberKey.BusinessPhone, out number);
if ((numberFound && number != customContact.WorkPhone) || (!numberFound && !string.IsNullOrEmpty(customContact.WorkPhone)))
{
    updateContact.PhoneNumbers[PhoneNumberKey.BusinessPhone] = customContact.WorkPhone == "" ? null : customContact.WorkPhone;
}

PhysicalAddressEntry phsicalAddress;

int phsicalAddressLength = (customContact.Street + customContact.Suburb + customContact.City + customContact.Country + customContact.AreaCode).Length;

答案 1 :(得分：0)

您是否尝试过使用Microsoft在their example中使用的方式来更新商家地址：

PhysicalAddressEntry PABusinessEntry = new PhysicalAddressEntry();
PABusinessEntry.Street = "4567 Contoso Way";
PABusinessEntry.City = "Redmond";
PABusinessEntry.State = "OH";
PABusinessEntry.PostalCode = "33333";
PABusinessEntry.CountryOrRegion = "United States of America";
contact.PhysicalAddresses[PhysicalAddressKey.Business] = PABusinessEntry;

这样就创建了一个新的PhysicalAddressEntry-object，它可以解决你的问题。

（当然这对电话号码没有帮助。）
