我试图向我的Exchange 2010 SP2服务器发送一个简单的SOAP请求，以便ICalUid找到一个受this great answer by Glen启发的会议。
'<soap:Envelope ' +
'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
'xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" ' +
'xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types" ' +
'xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">' +
' <soap:Header>' +
' <t:RequestServerVersion Version="Exchange2010_SP2"/>' +
' </soap:Header>' +
' <soap:Body>' +
' <m:FindItem Traversal="Shallow">' +
' <m:ItemShape>' +
' <t:BaseShape>AllProperties</t:BaseShape>' +
' </m:ItemShape>' +
' <m:Restriction>' +
' <t:IsEqualTo>' +
' <t:ExtendedFieldURI DistinguishedPropertySetId="Meeting" PropertyId="0x03" PropertyType="Binary"/>' +
' <t:FieldURIOrConstant>' +
' <t:Constant Value="bbkpr55lqbc49acfg9objhg40g" />' +
' </t:FieldURIOrConstant>' +
' </t:IsEqualTo>' +
' </m:Restriction>' +
' <m:ParentFolderIds>' +
' <t:DistinguishedFolderId Id="calendar" />' +
' </m:ParentFolderIds>' +
' </m:FindItem>'
' </soap:Body>' +
'</soap:Envelope>';
这会产生以下错误：
The 'PropertyId' attribute is invalid - The value '0x03' is invalid according to its datatype 'http://www.w3.org/2001/XMLSchema:int' - The string '0x03' is not a valid Int32 value.
这显然不是Int32值，但为什么PropertyType="Binary"没有任何影响？
