可以使用biztalk提供的ExplorerOM名称空间下的API对biztalk的各个组件进行管理，做Biztalk Administration Console做的那些管理任务，比如查看biztalk服务器上有多少个application，某个Application中有多少接收端口，有多少发送端口，增加删除Receive Location，增加删除发送端口等等。
BtsCatalogExplorer是ExplorerOM中的核心类，biztalk中的所有组件都通过BtsCatalogExplorer类对外暴露。
BtsCatalogExplorer的各种操作实际上是对biztalk的BizTalkMgmtDb数据库的操作，因为biztalk的静态信息，包括这个biztalk服务上有什么Application，接收端口，发送端口，有什么适配器，handler等等都保存在BizTalkMgmtDb数据库。
如果要对biztalk中的某个组件进行操作，必须先初始化一个BtsCatalogExplorer对象，并将需要操作的那个biztalk服务器相应的BizTalkMgmtDb数据库的连接字符串赋给BtsCatalogExplorer的ConnectionString属性。
BtsCatalogExplorer对biztalk组件的修改都是在内存中进行，只有当执行到SaveChanges方法时，才会把所有的修改一次性提交到BizTalkMgmtDb数据库做实际的修改。
这里以实例说明使用ExplorerOM对象模型新建receive location过程。
代码下载：CreateReceiveLocation.rar
一、 新建File adapter的Receive Location
用下面代码在“My Receive Port”接收端口下新建一个name为“Receive Location6 - Code Created user”的File类型的Receive Location。
BtsCatalogExplorer root = new BtsCatalogExplorer();
try
{
root.ConnectionString = "Data Source=.;Initial Catalog=BizTalkMgmtDb;Integrated Security=SSPI;";
ReceivePort rp = root.ReceivePorts["My Receive Port"];
ReceiveLocation rl = rp.AddNewReceiveLocation();
rl.Name = "Receive Location6 - Code Created user";
rl.Address = "c:\\temp\\te*.xml";
foreach (ReceiveHandler handler in root.ReceiveHandlers)
{
if (handler.TransportType.Name == "FILE" && handler.Name == "BizTalkServerApplication")
{
rl.ReceiveHandler = handler;
break;
}
}
Microsoft.BizTalk.ExplorerOM.ProtocolType protocol = root.ProtocolTypes["FILE"];
rl.TransportType = protocol;
rl.ReceivePipeline = root.Pipelines[typeof(PassThruReceive).FullName, typeof(PassThruReceive).Assembly.FullName];
string proStr = "<CustomProps><RemoveReceivedFileRetryCount vt=\"19\">51</RemoveReceivedFileRetryCount><RemoveReceivedFileMaxInterval vt=\"19\">300001</RemoveReceivedFileMaxInterval><FilePath vt=\"8\">F:\\temp</FilePath><FileMask vt=\"8\">pe*.xml</FileMask><Username vt=\"8\">a</Username><BatchSizeInBytes vt=\"19\">102401</BatchSizeInBytes><PollingInterval vt=\"19\">60001</PollingInterval><BatchSize vt=\"19\">21</BatchSize><Password vt=\"1\">a</Password><FileNetFailRetryInt vt=\"19\">51</FileNetFailRetryInt><RemoveReceivedFileDelay vt=\"19\">11</RemoveReceivedFileDelay><RenameReceivedFiles vt=\"11\">0</RenameReceivedFiles><FileNetFailRetryCount vt=\"19\">51</FileNetFailRetryCount></CustomProps>";
rl.TransportTypeData = proStr;
rl.FragmentMessages = Fragmentation.Yes;
rl.ServiceWindowEnabled = false;
rl.Enable = true;
root.SaveChanges();
}
catch (Exception e)
{
root.DiscardChanges();
throw e;
}
需要注意的是，ReceiveLocation的TransportTypeData属性。不同的适配器有不同的属性集，biztalk通过这个TransportTypeData属性接收这些不同的属性，属性的数据类型是string，实际上是name/value对组成的xml形式的属性集合。类似这样的形式，包括了File adapter所有的定制属性了：
<CustomProps>
<RemoveReceivedFileRetryCount vt="19">51</RemoveReceivedFileRetryCount>
<RemoveReceivedFileMaxInterval vt="19">300001</RemoveReceivedFileMaxInterval>
<FilePath vt="8">F:\temp</FilePath>
<FileMask vt="8">te*.xml</FileMask>
<Username vt="8">a</Username>
<BatchSizeInBytes vt="19">102401</BatchSizeInBytes>
<PollingInterval vt="19">60001</PollingInterval>
<BatchSize vt="19">21</BatchSize>
<Password vt="1" >password</Password>
<FileNetFailRetryInt vt="19">51</FileNetFailRetryInt>
<RemoveReceivedFileDelay vt="19">11</RemoveReceivedFileDelay>
<RenameReceivedFiles vt="11">0</RenameReceivedFiles>
<FileNetFailRetryCount vt="19">51</FileNetFailRetryCount>
</CustomProps>
ReceiveLocation.Address属性很重要，这个属性就是biztalk Administration Console中Receive Location列表中，Receive Location的URI属性，指示这个Location接收消息的位置，这个URI在一个biztalk server上所有Receive Location中必须唯一。
对于File适配器，ReceiveLocation.Address属性由File adater的FilePath和Filemask属性组合而成。在新建File的Receive Location时，必须设置ReceiveLocation.Address，如果同时在TransportTypeData设置了FilePath和Filemask属性，ReceiveLocation.Address会覆盖FilePath和Filemask属性的设置，所以，没必要在TransportTypeData中设置FilePath和Filemask属性。
一、 新建FTP adapter的Receive Location
同样可以在代码中使用ExplorerOM新建一个使用FTP适配器的Receive Location，下面是代码，跟建立File的Location稍有不同：
BtsCatalogExplorer root = new BtsCatalogExplorer();
try
{
root.ConnectionString = "Data Source=.;Initial Catalog=BizTalkMgmtDb;Integrated Security=SSPI;";
string proStr = "<Config xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"><serverAddress>chnking1.com</serverAddress><serverPort>21</serverPort><userName>kent</userName><password /><fileMask>1*.xml</fileMask><targetFolder>testFolder1</targetFolder><representationType>binary</representationType><maximumBatchSize>0</maximumBatchSize><maximumNumberOfFiles>0</maximumNumberOfFiles><passiveMode>False</passiveMode><firewallType>NoFirewall</firewallType><firewallPort>21</firewallPort><pollingUnitOfMeasure>Seconds</pollingUnitOfMeasure><pollingInterval>60</pollingInterval><errorThreshold>10</errorThreshold><maxFileSize>100</maxFileSize><uri>ftp://chnking.com:21/testFolder/*.xml</uri></Config>";
proStr = CreateLocationTransportData(proStr);
ReceivePort rp = root.ReceivePorts["My Receive Port"];
ReceiveLocation rl = rp.AddNewReceiveLocation();
rl.Name = "Receive Location FTP - Code Created";
rl.Address = "ftp://chnking.com:21/testFolder/t*.xml";
foreach (ReceiveHandler handler in root.ReceiveHandlers)
{
if (handler.TransportType.Name == "FTP" && handler.Name == "BizTalkServerApplication")
{
rl.ReceiveHandler = handler;
break;
}
}
Microsoft.BizTalk.ExplorerOM.ProtocolType protocol = root.ProtocolTypes["FTP"];
rl.TransportType = protocol;
rl.ReceivePipeline = root.Pipelines[typeof(PassThruReceive).FullName, typeof(PassThruReceive).Assembly.FullName];
rl.TransportTypeData = proStr;
rl.FragmentMessages = Fragmentation.Yes;
rl.ServiceWindowEnabled = false;
rl.Enable = true;
root.SaveChanges();
}
catch (Exception e)
{
root.DiscardChanges();
throw e;
}
FTP适配器具有的定制属性有下面这些：
<Config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<serverAddress>chnking.com</serverAddress>
<serverPort>21</serverPort>
<userName>kent</userName>
<password />
<fileMask>*.xml</fileMask>
<targetFolder>testFolder</targetFolder>
<representationType>binary</representationType>
<maximumBatchSize>0</maximumBatchSize>
<maximumNumberOfFiles>0</maximumNumberOfFiles>
<passiveMode>False</passiveMode>
<firewallType>NoFirewall</firewallType>
<firewallPort>21</firewallPort>
<pollingUnitOfMeasure>Seconds</pollingUnitOfMeasure>
<pollingInterval>60</pollingInterval>
<errorThreshold>10</errorThreshold>
<maxFileSize>100</maxFileSize>
</Config>
但是跟File适配器不同，FTP适配器需要的TransportTypeData比较特别，需要下面的形式：
需要把前面<Config>节部分的内容转成字符串格式，然后嵌入到<CustomProps>的<AdapterConfig>节点下，代码中proStr = CreateLocationTransportData(proStr);就是用来做这个转换的：
private static string CreateLocationTransportData(string configString)
{
XmlDocument xd = new XmlDocument();
XmlElement xeRoot = xd.CreateElement("CustomProps");
xd.AppendChild(xeRoot);
XmlElement xeConfig = xd.CreateElement("AdapterConfig");
xeRoot.AppendChild(xeConfig);
XmlAttribute xaVT = xd.CreateAttribute("vt");
xeConfig.Attributes.Append(xaVT);
xaVT.Value = "8";
XmlDocument myXmlDocument = new XmlDocument();
myXmlDocument.LoadXml(configString);
xeConfig.InnerText = myXmlDocument.DocumentElement.OuterXml;
return xd.InnerXml;
}
处理过的TransportTypeData数据是这样的：
<CustomProps>
<AdapterConfig vt="8"><Config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><serverAddress>chnking1.com</serverAddress><serverPort>21</serverPort><userName>kent</userName><password /><fileMask>1*.xml</fileMask><targetFolder>testFolder1</targetFolder><representationType>binary</representationType><maximumBatchSize>0</maximumBatchSize><maximumNumberOfFiles>0</maximumNumberOfFiles><passiveMode>False</passiveMode><firewallType>NoFirewall</firewallType><firewallPort>21</firewallPort><pollingUnitOfMeasure>Seconds</pollingUnitOfMeasure><pollingInterval>60</pollingInterval><errorThreshold>10</errorThreshold><maxFileSize>100</maxFileSize></Config>
</AdapterConfig>
</CustomProps>
对于FTP适配器，ReceiveLocation.Address属性由FTP adater的serverAddress、serverPort、targetFolder和fileMask属性组合而成，但是在新建FTP Receive Location的代码中ReceiveLocation.Address和TransportTypeData的serverAddress等属性也都需要设置，所以请保证两边设置的值是一致的。
