问题描述

我正在使用Microsoft.Exchange.WebServices.dll（v 15.0.466.0）在C＃VS2010中发送测试邮件。请参阅下面的代码

自动发现似乎工作正常，即。在跟踪中，我可以发现我的名字：

< Trace Tag =" AutodiscoverResponse" TID = QUOT 1 QUOT;时间=" 2012-08-22 05：25：11Z"版本=" 15.00.0466.000">

< Autodiscover xmlns =" http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006">

      <用户>

        < DisplayName> =我< / DisplayName>

      < / User>

但之后，每次出现此错误时：

解决方案

版本2.0处于测试阶段，因此，除非您针对2012进行开发，否则最好使用托管API的发布版本1.2 http://www.microsoft.com/en-au/download/details.aspx?id=28952。

NET 4.5对 4.0的RTM版本进行更改并更改'mscorlib'，请参阅

http://connect.microsoft。含extensionmethods和 - 可能 - 其他-IOC情节移动系统的运行时-compilerservices-extensionattribute到mscorlib程序-场所-structuremap-扫描-的名字空间-&NBSP;所以要在Windows 7上成功使用此
，您需要安装.NET 4.5的RC，这也将改变它们在.NET 4.0中的类型。如果您拥有Windows 8的RTM版本，则不应该出现问题。

Hi,

I'm using Microsoft.Exchange.WebServices.dll (v 15.0.466.0) to send a test message in C# VS2010. See code below

The Autodiscover seems to work fine ie. in the traces, I can spot my name :

But afterwards, each time I got this error:

Unhandled Exception: System.TypeInitializationException: The type initializer for 'Microsoft.Exchange.WebServices.Strings' threw an exception. ---> System.TypeL
oadException: Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken

==> i have used all ExchangeVersion.xxx at line : ExchangeService service = new ExchangeService(ExchangeVersion.xxx)

==> I have installed the .exe on a test machine

Still dosesn't work :(

Please help

解决方案

Version 2.0 is in Beta so unless you developing against 2012 you would be better to use the release version 1.2 of the managed apihttp://www.microsoft.com/en-au/download/details.aspx?id=28952.

NET 4.5 makes changes to the RTM version of 4.0 and changes 'mscorlib' see http://connect.microsoft.com/VisualStudio/feedback/details/726702/moving-system-runtime-compilerservices-extensionattribute-to-mscorlib-breaks-structuremap-scans-of-namespaces-containing-extensionmethods-and-possibly-other-ioc-scenarios so to use this successfully on Windows 7 you need to have the RC of .NET 4.5 installed which will change they types in .NET 4.0 as well. If you have the RTM version of Windows 8 you shouldn't have a problem.
