更新与EWS的联系

Question

我一直在努力寻找如何与EWS合作，并设法解决如何处理我想要的一切。我正在使用EWS来管理自定义数据库与Exchange服务器（2007）之间的联系。添加和删​​除作品很好，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该联系人，但是当通过Outlook编辑联系人时（或者其他），问题就出现了。

我想请点击此链接说什么：

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

，但我得到一个错误，指出只有一个属性可以更新。然后我每次更新一个属性，当我尝试更新电话号码时，我收到一个错误消息，内容如下：“名称空间中的元素'Updates'http://schemas.microsoft.com/exchange/services/2006/types'内容不完整。“

下面是代码，基本上是：

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

有谁知道为什么我得到这个错误？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。

Answer 1

经过多次调试，我找到了答案。我不打算去探索更多的找出原因，但你不能做到这一点：

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); 

你可以，但是，只设定一个电话号码，然后在调试时更改值对于其他两个（而在一个断点）。奇怪的。

无论如何，存在一个问题 - 如果值没有改变（这就是答案，不能更新这些字典值中的一个），所以首先检查值是否改变。接下来，如果一个值是一个空字符串，则需要将其保存为空值。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); 
} 

要更新地址：

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); 

这，在我看来，是草率的API实现（与文档质量很差）的。

需要对项目的每个属性执行更新的事实可能是由于运行Exchange 2007的服务器导致的，但尚未得到确认。

我试用了Microsoft.Exchange.WebServices的14和15版本，结果相同。

更新

别急，还有更精彩的。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 - 如果您想要在Outlook中显示，则需要将用户定义的字段添加到联系人文件夹）。

这里是一个代码完整，工作片：

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

{ 
    updateContact.PhysicalAddresses[PhysicalAddressKey.Home] = homeAddress; 
} 
phsicalAddressLength = (customContact.BusinessStreet + customContact.BusinessSuburb + customContact.BusinessCity + customContact.BusinessCountry + customContact.BusinessAreaCode).Length; 
phsicalAddressFound = updateContact.PhysicalAddresses.TryGetValue(PhysicalAddressKey.Business, out phsicalAddress);

    { 
     case "Male":

     case "Female": 
      updateContact.SetExtendedProperty(extendedPropertyDefinition, 1); 
      break; 
     default: 
      updateContact.SetExtendedProperty(extendedPropertyDefinition, 3); 
      break;

Answer 2

您是否尝试过使用微软在their example使用的方式来更新办公地址：

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; 

这样一个新的PhysicalAddressEntry -object被创建可以解决你的问题。

（当然这不适合的电话号码。帮助）
