能否具体解释一下这里的Client程序，譬如？Top

就是我用自己写的exe程序去终止Biztalk中被挂起的业务流程实例。Top

BTS主要用来完成一个完整的业务流程，中间出现的任务问题都可以在HAT中找到答案。
如果你非要实现使用Client去控制一个流程，就要对MessageBoxDB非常了解，并对数据直接进行操作。
以我现在对BTS的研究成度，暂时还无法找到一个合适的方案来解决你的问题。

可以通过调用Biztalk的WMI对象来解决这个问题，如下示例代码：
using System.Management;
public void ResumeSvcInstByOrchestrationName(string strOrchestrationName)
{
try
{
const uint SERVICE_CLASS_ORCHESTRATION = 1;
const uint SERVICE_STATUS_SUSPENDED_RESUMABLE = 4;
const uint REGULAR_RESUME_MODE = 1;
// Query for suspended (resumable) service instances of the specified orchestration
// Suggestion: Similar queries can be written for Suspend/Terminate operations by using different ServiceStatus value. See MOF definition for details.
string strWQL = string.Format(
"SELECT * FROM MSBTS_ServiceInstance WHERE ServiceClass = {0} AND ServiceStatus = {1} AND ServiceName = \"{2}\"",
SERVICE_CLASS_ORCHESTRATION.ToString(), SERVICE_STATUS_SUSPENDED_RESUMABLE.ToString(), strOrchestrationName);
ManagementObjectSearcher searcherServiceInstance = new ManagementObjectSearcher (new ManagementScope ("root\\MicrosoftBizTalkServer"), new WqlObjectQuery(strWQL), null);
int nNumSvcInstFound = searcherServiceInstance.Get().Count;
// If we found any
if ( nNumSvcInstFound > 0 )
{
// Construct ID arrays to be passed into ResumeServiceInstancesByID() method
string[] InstIdList = new string[nNumSvcInstFound];
string[] ClassIdList = new string[nNumSvcInstFound];
string[] TypeIdList = new string[nNumSvcInstFound];
string strHost = string.Empty;
string strReport = string.Empty;
int i = 0;
foreach ( ManagementObject objServiceInstance in searcherServiceInstance.Get() )
{
// It is safe to assume that all service instances belong to a single Host.
if ( strHost == string.Empty )
strHost = objServiceInstance["HostName"].ToString();
ClassIdList[i] = objServiceInstance["ServiceClassId"].ToString();
TypeIdList[i] = objServiceInstance["ServiceTypeId"].ToString();
InstIdList[i] = objServiceInstance["InstanceID"].ToString();
strReport += string.Format(" {0}\n", objServiceInstance["InstanceID"].ToString());
i++;
}
// Load the MSBTS_HostQueue with Host name and invoke the "ResumeServiceInstancesByID" method
string strHostQueueFullPath = string.Format("root\\MicrosoftBizTalkServer:MSBTS_HostQueue.HostName=\"{0}\"", strHost);
ManagementObject objHostQueue = new ManagementObject(strHostQueueFullPath);
// Note: The ResumeServiceInstanceByID() method processes at most 2047 service instances with each call.
// If you are dealing with larger number of service instances, this script needs to be modified to break down the
// service instances into multiple batches.
objHostQueue.InvokeMethod("ResumeServiceInstancesByID",
new object[] {ClassIdList, TypeIdList, InstIdList, REGULAR_RESUME_MODE}
);
Console.WriteLine( string.Format("Service instances with the following service instance IDs have been resumed:\n{0}", strReport) );
}
else
{
System.Console.WriteLine(string.Format("There is no suspended (resumable) service instance found for orchestration '{0}'.", strOrchestrationName));
}
}
catch(Exception excep)
{
Console.WriteLine("Error: " + excep.Message);
}
