更新與EWS的聯繫

Question

我一直在努力尋找如何與EWS合作，並設法解決如何處理我想要的一切。我正在使用EWS來管理自定義數據庫與Exchange服務器（2007）之間的聯繫。添加和刪​​除作品很好，但我無法更新聯繫人。爲了解決這個問題，我刪除了聯繫人並重新創建了該聯繫人，但是當通過Outlook編輯聯繫人時（或者其他），問題就出現了。

我想請點擊此鏈接說什麼：

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

，但我得到一個錯誤，指出只有一個屬性可以更新。然後我每次更新一個屬性，當我嘗試更新電話號碼時，我收到一個錯誤消息，內容如下：「名稱空間中的元素'Updates'http://schemas.microsoft.com/exchange/services/2006/types'內容不完整。「

下面是代碼，基本上是：

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

有誰知道爲什麼我得到這個錯誤？任何人都可以回答如何實際更新項目？我有錯過的文件嗎？

EWS dll的版本是15.0.516.12。

Answer 1

經過多次調試，我找到了答案。我不打算去探索更多的找出原因，但你不能做到這一點：

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，只設定一個電話號碼，然後在調試時更改值對於其他兩個（而在一個斷點）。奇怪的。

無論如何，存在一個問題 - 如果值沒有改變（這就是答案，不能更新這些字典值中的一個），所以首先檢查值是否改變。接下來，如果一個值是一個空字符串，則需要將其保存爲空值。您還需要在嘗試讀取其值之前檢查字典條目是否存在。

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); 

這，在我看來，是草率的API實現（與文檔質量很差）的。

需要對項目的每個屬性執行更新的事實可能是由於運行Exchange 2007的服務器導致的，但尚未得到確認。

我試用了Microsoft.Exchange.WebServices的14和15版本，結果相同。

更新

別急，還有更精彩的。該代碼還顯示瞭如何更新（或設置）標題，性別，後綴和自定義屬性（用戶定義的字段 - 如果您想要在Outlook中顯示，則需要將用戶定義的字段添加到聯繫人文件夾）。

這裏是一個代碼完整，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;

Answer 2

您是否嘗試過使用微軟在their example使用的方式來更新辦公地址：

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; 

這樣一個新的PhysicalAddressEntry -object被創建可以解決你的問題。

（當然這不適合的電話號碼。幫助）
