  指示网格是否为顶级（级别 1）网格。

• rGridMinX
  Type: System.Double

  网格左下角的 x 坐标。

• rGridMinY
  Type: System.Double

  网格左下角的 y 坐标。

• rGridWidth
  Type: System.Double

  网格的宽度。

• rGridHeight
  Type: System.Double

  网格的高度。

• rFuzzX
  Type: System.Double

  x 坐标容差值。

• rFuzzY
  Type: System.Double

  y 坐标容差值。

• cGridRows
  Type: System.Int32

  网格中的行数。

• cGridColumns
  Type: System.Int32

  网格中的列数。

• touched
  Type: System.Boolean[,]

  bool 值的二维数组，指定单元是否与对象接触。

• contained
  Type: System.Boolean[,]

  bool 值的二维数组，指定单元是否包含对象。

• cCellsTouched
  Type: System.Int32

  在此方法返回时，包含对象接触的单元的数目。

• cCellsContained
  Type: System.Int32

  在此方法返回时，包含对象包含的单元的数目。

• fGeometryExceedsGrid
