windows服务的问题。请帮忙

在服务器写了一个服务：
让他一直循环做轮训然后做业务。处理。但是因为业务处理的代码需要的时间比较多。在业务还没所有处理完毕。服务就不管了。然后继续做轮训来监控循环了。请问我如何控制服务。必须让他当前的轮训执行完我这次的业务以后。才能进行下一次的轮训了。
代码如下：
private void StartMonitor()
{
int SleepTime = 3000;//3秒

while (true)
{
try
{
foreach (string FolderPath in FoldersPath)
{

string SqlconnectionString = InitalContextInfo(FolderPath);
DataBaseService.connectionString = SqlconnectionString;
try
{
//判断文件是否上传完毕。如果已经完毕就对上传文件进行数据库的处理。
DataSet e = DataBaseService.Query("select * from FileInfo where IfTransferd=0 and Mergeing=0");
if (e != null)
{
foreach (DataRow dr in e.Tables[0].Rows)
{
string Guid = dr["Id"].ToString();
string Filename = dr["FileName"].ToString();
long FileSize = long.Parse(dr["FileSize"].ToString());
int Totaloffset = int.Parse(dr["Totaloffset"].ToString());
//string Filepath = ServicePath + "\\ServiceStorage\\" + Filename;
string Filepath = FolderPath + "\\ServiceStorage\\" + Filename;
string RequestUser = dr["RuquestUser"].ToString();
if (!System.IO.File.Exists(Filepath)) continue;
System.IO.FileInfo fi = new System.IO.FileInfo(Filepath);
long Filelegtn = fi.Length;
if (Filelegtn >= FileSize) //判断上传完毕
{
int value = DataBaseService.ExecuteSql(" update FileInfo set Mergeing=1,IfTransferd=1 where id='" + Guid + "'");
DoDataBaseBO(RequestUser，Filepath);//执行业务处理
}
}
}
}
catch
{}
}
} catch
{}

Thread.Sleep(SleepTime);
}

}
/// <summary>
