栅格波段：也叫波普段或波普带。在电磁波中，具有确定波长范围的连续电磁波。
不同的栅格图层具有的波段数不一样，有单波段的图层，也有多波段的图层。
多波段图层示意图：
//获取波段数 private void button1_Click(object sender, EventArgs e) { IRasterLayer lyr = axMapControl1.get_Layer(0) as IRasterLayer; int bandcount = lyr.BandCount; MessageBox.Show(bandcount.ToString()); } //统计行数 private void button2_Click(object sender, EventArgs e) { IRasterLayer lyr = axMapControl1.get_Layer(0) as IRasterLayer; int row = lyr.RowCount; MessageBox.Show(row.ToString()); } //获取列数，像元个数就是行列数相乘 private void button3_Click(object sender, EventArgs e) { IRasterLayer lyr = axMapControl1.get_Layer(0) as IRasterLayer; int column = lyr.ColumnCount; MessageBox.Show(column.ToString()); }
