依然跪求大神指点迷津

将LicenseControl控件拖到窗体的任意位置就好了。

LoadStyleFile参数你使用绝对路径试试看！ 再看看别人怎么说的。

//Get the ArcGIS install location string sInstall = ESRI.ArcGIS.RuntimeManager.ActiveRuntime.Path; //Load the ESRI.ServerStyle file into the SymbologyControl axSymbologyControl1.LoadStyleFile(sInstall + "\\Styles\\ESRI.ServerStyle");
