how to set the name of a raster band in c#?

I have a small extension to create a raster dataset with 5 bands into a GDB.  this works no problem, but I am struggling to set the name of each band to the correct name rather than the default 'value'.

Does anyone know of a code snippet to set the name of a band?

Here is a code snippet to create the bands.  It works fine, but the names are unrealistic.

//Define the origin for the raster dataset, which is the lower left corner of the raster.
            IPoint origin = new PointClass();
            origin.PutCoords(lowerLeft.x, lowerLeft.y);
            //Define the dimension of the raster dataset.
            int width = nColumns; //This is the width of the raster dataset.
            int height = nRows; //This is the height of the raster dataset.
            double xCell = cellSize; //This is the cell size in x direction.
            double yCell = cellSize; //This is the cell size in y direction.
            int NumBand = 5; // This is the number of bands the raster dataset contains.
            //Create a raster dataset in grid format.
            rasterDataset = rasterWs.CreateRasterDataset(rasterFilename, "GRID", origin, width, height, xCell, yCell, NumBand, rstPixelType.PT_FLOAT, sr, true);

            //Get the raster band.
            IRasterBandCollection rasterBands = (IRasterBandCollection)rasterDataset;
            IRasterBand rasterBand;
            IRasterProps rasterProps;
            rasterBand = rasterBands.Item(0);
            rasterProps = (IRasterProps)rasterBand;
            //Set NoData if necessary. For a multiband image, NoData value needs to be set for each band.
            const double NoDataValue = -9999.99;
            rasterProps.NoDataValue = Convert.ToSingle(NoDataValue);
            //Create a raster from the dataset.
            IRaster raster = rasterDataset.CreateDefaultRaster();
            IRasterEdit rasterEdit = (IRasterEdit)raster;

This may provide you with what you need.  In this example they are creating rasters from TIFF objects and assigning names.

To change ESRI.ArcGIS.DataSourcesRaster.IRasterBand.Bandname property, you must cast ESRI.ArcGIS.DataSourcesRaster.IRasterBand object into ESRI.ArcGIS.Geodatabase.IDataset interface and run IDataset.Rename() method.
