New Post: Convert shapefile to raster

You should have a look at the DotSpatial.Analysis.VectorToRaster.ToRaster method and the parameters it requires and the work is done

            string shpFile = @"E:\Project\TestData\UpCatchment.shp";
            double xMin = 82292.591;

            IFeatureSet fs = FeatureSet.Open(shpFile);
            fs.FillAttributes();
            fs.DataTable.Columns.Add("myField");
            for (int i = 0; i < fs.Features.Count; i++)
            {
                fs.Features[i].DataRow.BeginEdit();
                fs.Features[i].DataRow["myField"] = 1;
                fs.Features[i].DataRow.EndEdit();
            }
            Extent extent = new Extent(new double[] {xMin, yMin, xMax,yMax});
            IRaster raster = VectorToRaster.ToRaster(fs, cellsize, "myField", "output.bgd", "", new string[] { }, null);
