Question

ArcGis Engine C# 用户代码未处理COMException 指定的文件名无效

private void axSymbolSelectorFrm_Load(object sender, EventArgs e)
{
//取得ArcGIS安装路径
string sInstall = ReadRegistry("SOFTWARE\\ESRI\\CoreRuntime");
//载入ESRI.ServerStyle文件到SymbologyControl
this.axSymbologyControl1.LoadStyleFile(sInstall + \\Styles\\ESRI.ServerStyle);——此句出错！！！！
//确定图层的类型(点线面),设置好SymbologyControl的StyleClass,设置好各控件的可见性(visible)
IGeoFeatureLayer pGeoFeatureLayer = (IGeoFeatureLayer)pLayer;
switch (((IFeatureLayer)pLayer).FeatureClass.ShapeType)
{
case ESRI.ArcGIS.Geometry.esriGeometryType.esriGeometryPoint:
this.SetFeatureClassStyle(esriSymbologyStyleClass.esriStyleClassMarkerSymbols);
this.lblAngle.Visible = true;
this.nudAngle.Visible = true;

this.nudSize.Visible = true;

break;

this.Close();
break;
}
}
。。。
依然跪求大神指点迷津

Answer 1

//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");

Answer 2

将LicenseControl控件拖到窗体的任意位置就好了。

Answer 3

LoadStyleFile参数你使用绝对路径试试看！

追问

谢谢，换了绝对路径就好了，但下句话又报错了
