AE二次开发引发异常“System.Runtime.InteropServices.COMException” 异常来自 HRESULT:0x80040351

[@SOAR]

开发环境vs2015+AE10.2，刚开始接触
//加载Shp格式文件
public ILayer AddShap(string strFileName)
{
string WorkSpacePath = System.IO.Path.GetDirectoryName(strFileName);
string strShapeFileNmeWithoutExtension = System.IO.Path.GetFileNameWithoutExtension(strFileName);
IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactory();
IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(WorkSpacePath, 0);

IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace;
IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(strShapeFileNmeWithoutExtension);

IDataset pDataset = pFeatureClass as IDataset;
IFeatureLayer pFeatureLayer = new FeatureLayer();

pFeatureLayer.Name = pDataset.Name;
ILayer pLayer = pFeatureLayer as ILayer;

return pLayer;
}
//将图层添加到MapControl的Map对象
ILayer mLayer =AddShap(strrPath);
axMapControl1.Map.AddLayer(mLayer);


语句： IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(strShapeFileNmeWithoutExtension);
引发异常：“System.Runtime.InteropServices.COMException”类型的未经处理的异常在 .exe 中发生
其他信息: 异常来自 HRESULT:0x80040351
怎样解决？还请各路英雄指点迷津！！

IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(strShapeFileNmeWithoutExtension); 实参与形参类型不符，OpenFeatureClass（）形参为不加后缀的文件名，传递的实参错误引起的常： 引发异常：“System.Runtime.InteropServices.COMException”类型的未经处理的异常在 .exe 中发生 其他信息: 异常来自 HRESULT:0x80040351

IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(strShapeFileNmeWithoutExtension); 拆分这一句，看看具体是哪个字段出了问题。

你是不是把扩展名也列进去了，OpenFeatureClass打开shapefile不能有扩展名
