<P><BR>c#2.0编译。<BR>运行时出错：Entry for SDE instance not found in services file<BR>我的机器名是qydlj <BR>数据库是sql server2000  sde默认安装<BR>我下载的arcSde管理器可以连接。不知是什么原因。请大侠赐教。</P>

你把 pPropertySet.SetProperty("Instance", "QYDLJ");改成 pPropSet.SetProperty ("INSTANCE", "port:5151"); ，”port:5151“是安装sde过程中默认的<BR>  

<P>谢谢，已成功！</P>
