这样动态发布地图资源为啥不行？

<p>{ if(!IsPostBack)</p>
<p> { MapResourceManager mapresourcemanager1 = new MapResourceManager();</p>
<p> MapResourceManager1.ResourceItems.Clear();</p>
<p> GISResourceItemDefinition definition = new GISResourceItemDefinition(); </p>
<p>definition.DataSourceDefinition = "192.168.10.254"; </p>
<p>definition.DataSourceType = "ArcGIS Server Local"; </p>
<p>definition.ResourceDefinition = "Layers@湖北来凤"; </p>
<p>definition.DataSourceShared = true; </p>
<p>DisplaySettings dissetting = new DisplaySettings(); </p>
<p>dissetting.Visible = true; dissetting.Transparency = 0;</p>
<p> dissetting.DisplayInTableOfContents = true;</p>
<p> if(dissetting==null) { Response.Write("
<script>alert()</script>
 "); } </p>
<p>MapResourceItem mapresoourceitem1 = new MapResourceItem(); </p>
<p>mapresoourceitem1.Name="mapresoourceitem1";</p>
<p> mapresoourceitem1.Definition = definition;</p>
<p> mapresoourceitem1.DisplaySettings = dissetting; </p>
<p>mapresoourceitem1.Parent = MapResourceManager1; </p>
<p>// MapResourceManager1.ResourceItems.Insert(0, mapresoourceitem1);</p>
<p> mapresourcemanager1.ResourceItems.Add(mapresoourceitem1);</p>
<p> MapResourceManager1.CreateResource(mapresoourceitem1); </p>
<p>mapresourcemanager1.Initialize(); mapresourcemanager1.Refresh(); </p>
<p>mapresourcemanager1.Refresh(); </p>
<p>Map1.MapResourceManagerInstance = MapResourceManager1;</p>
<p> Map1.MapResourceManager = MapResourceManager1.ToString();</p>
<p> Map1.InitializeFunctionalities();</p>
<p> if (Map1.ImageBlendingMode == ImageBlendingMode.WebTier)</p>
<p> { Map1.Refresh(); } else { // Map1.RefreshResource("mapresoourceitem1");</p>
<p> Map1.RefreshResource(mapresoourceitem1.Name);</p>
<p> }</p>
<p> MapResourceManager1.Refresh();</p>
<p> } </p>
<p>} </p>

这样贴代码很难看，能否把要实现的效果和错误提示贴出来

<p>本地数据可以用机器名称</p>
<p>外地数据用<font face="Verdana">ArcGIS Server Internet</font>连接吧</p>
