获取栅格图层（Raster）的属性表

矢量图层的属性表相信大家都会操作就不多说了,下面说说栅格图层的属性表操作

pNewRaster是你的Raster图层

IRasterBandCollection pRasterBC =(IRasterBandCollection ) pNewRaster;

IRasterBand pRasterBand = pRasterBC.Item(0);

ITable pTable = pRasterBand.AttributeTable;

IQueryFilter pQueryFilter=new QueryFilterClass ();

pQueryFilter .WhereClause ="";

ICursor pCursor = pTable.Search(pQueryFilter, false);

IRow pRow = pCursor.NextRow();             

for (int i = 0; i < pTable .Fields .FieldCount; i++)

{

     MessageBox.Show(pTable .Fields .get_Field (i).Name);    //字段名字

}

while (pRow != null)

{

    //以下显示COUNT字段的值

MessageBox.Show(Convert.ToString(pRow.get_Value(pTable.Fields.FindField("COUNT"))));

    pRow = pCursor.NextRow();

}
