【问题描述】：
我们有一个 c# 应用程序，它使用 http 服务读取当前托管在 Exchange 2003 上的电子邮件收件箱。
现在邮箱要迁移到 Exchange 2010 服务器，所以我们正在测试我们的代码以确认它仍然可以工作。
我们收到错误“错误请求”，代码如下（试图获取所有邮件）： 公共静态 XmlDocument GetUnreadMailAll() { HttpWebRequest loRequest = 默认（HttpWebRequest）； HttpWebResponse loResponse = 默认（HttpWebResponse）； 字符串 lsRootUri = null; 字符串 lsQuery = null; byte[] laBytes = null;
Stream loRequestStream = default(Stream);
Stream loResponseStream = default(Stream);
XmlDocument loXmlDoc = default(XmlDocument);
loXmlDoc = new XmlDocument();
try
{
lsRootUri = strServer + "/Exchange/" + strAlias + "/" + strInboxURL;
lsQuery = "<?xml version=\"1.0\"?>"
+ "<D:searchrequest xmlns:D = \"DAV:\" xmlns:m=\"urn:schemas:httpmail:\">"
+ "<D:sql>SELECT "
+ "\"urn:schemas:httpmail:to\", "
+ "\"urn:schemas:httpmail:displayto\", "
+ "\"urn:schemas:httpmail:from\", "
+ "\"urn:schemas:httpmail:fromemail\", "
+ "\"urn:schemas:httpmail:subject\", "
+ "\"urn:schemas:httpmail:textdescription\", "
//+ "\"urn:schemas:httpmail:htmldescription\", "
+ "\"urn:schemas:httpmail:hasattachment\", "
+ "\"urn:schemas:httpmail:attachmentfilename\", "
+ "\"urn:schemas:httpmail:senderemail\", "
+ "\"urn:schemas:httpmail:sendername\", "
+ "\"DAV:displayname\", "
+ "\"urn:schemas:httpmail:datereceived\", "
+ "\"urn:schemas:httpmail:read\", "
+ "\"DAV:id\" "
+ "FROM \"" + lsRootUri
+ "\" WHERE \"DAV:ishidden\" = false "
+ "AND \"DAV:isfolder\" = false "
+ "AND \"urn:schemas:httpmail:read\" = false "
+ "AND \"urn:schemas:httpmail:fromemail\" != 'emailAddy@domainName.co.uk' "
+ "</D:sql></D:searchrequest>";
loRequest = (HttpWebRequest)WebRequest.Create(lsRootUri);
loRequest.Credentials = new NetworkCredential(strUserName, strPassword);
loRequest.Method = "SEARCH";
laBytes = System.Text.Encoding.UTF8.GetBytes(lsQuery);
loRequest.ContentLength = laBytes.Length;
loRequestStream = loRequest.GetRequestStream();
loRequestStream.Write(laBytes, 0, laBytes.Length);
loRequestStream.Close();
loRequest.ContentType = "text/xml";
loRequest.Headers.Add("Translate", "F");
loResponse = (HttpWebResponse)loRequest.GetResponse();
loResponseStream = loResponse.GetResponseStream();
loXmlDoc.Load(loResponseStream);
loResponseStream.Close();
}
在loResponseStream = loResponse.GetResponseStream();这一行抛出异常
这是我们发送的 xml：
<?xml version="1.0" ?>
- <D:searchrequest xmlns:D="DAV:" xmlns:m="urn:schemas:httpmail:">
<D:sql>SELECT "urn:schemas:httpmail:to", "urn:schemas:httpmail:displayto", "urn:schemas:httpmail:from", "urn:schemas:httpmail:fromemail", "urn:schemas:httpmail:subject", "urn:schemas:httpmail:textdescription", "urn:schemas:httpmail:hasattachment", "urn:schemas:httpmail:attachmentfilename", "urn:schemas:httpmail:senderemail", "urn:schemas:httpmail:sendername", "DAV:displayname", "urn:schemas:httpmail:datereceived", "urn:schemas:httpmail:read", "DAV:id" FROM "https://domain/Exchange/bbtest/Inbox" WHERE "DAV:ishidden" = false AND "DAV:isfolder" = false AND "urn:schemas:httpmail:read" = false AND "urn:schemas:httpmail:fromemail" != 'emailAddy@domainName.co.uk'</D:sql>
</D:searchrequest>
