ArcGIS Engine打开栅格数据失败，求解答

应该是给的参数不对，应该是完整路径吧，你这个有文件名吗？

public ESRI.ArcGIS.Geodatabase.IGeoDataset OpenRasterFileAsGeoDatset(System.String path, System.String name)
{

    try
    {

        ESRI.ArcGIS.Geodatabase.IWorkspaceFactory workspaceFactory = new ESRI.ArcGIS.DataSourcesRaster.RasterWorkspaceFactoryClass();
        ESRI.ArcGIS.DataSourcesRaster.IRasterWorkspace rasterWorkspace = (ESRI.ArcGIS.DataSourcesRaster.IRasterWorkspace)(workspaceFactory.OpenFromFile(path, 0));
        ESRI.ArcGIS.Geodatabase.IRasterDataset rasterDataset = rasterWorkspace.OpenRasterDataset(name);
        ESRI.ArcGIS.Geodatabase.IGeoDataset geoDataset = (ESRI.ArcGIS.Geodatabase.IGeoDataset)rasterDataset; // Explicit Cast

        return geoDataset;

    }
    catch (System.Exception ex)
    {

        //System.Diagnostics.Debug.WriteLine(ex.Message)
        return null;

    }
