各位大侠，我的WinForm的客户端在调用WCF服务的时候发现，就算函数返回一个很小的数，也很慢。我打了一下断点跟踪了一下，发现是在客户端代理调用WCF服务端函数的时候，要很长一段时间才能从客户端转到服务端，就像客户端调用的函数要找到服务端的服务很费劲一样，但是从服务端返回却很快，不知道是怎么回事

贴上代码，给你分析
private void initDB()
{
try
{
if (serviceHosts != null)

{
if (t != null)
t.Close();
}

}
else

foreach (Type t in types)
{

if (!serviceAddress.EndsWith("/"))
{
endpointAddress = string.Format("{0}/{1}", serviceAddress, tName);
