首先添加一個新的windows窗體frmAttribute,在上面添加個datagridview控件，用來顯示圖層屬性！

定義frmAttribute中的全局變量：

 private ILayer pLayer;;//打開屬性表的圖層
 private IFeatureLayer pFeatureLayer;
 private IFeatureClass pFeatureClass;
 private ILayerFields pLayerFields;

 修改構造函數，傳入要打開屬性表的圖層：

public frmAttribute( ILayer pLyr)
{
 InitializeComponent();
 
// m_MapControl = pMapControl;
 pLayer = pLyr;
 }

 在右鍵菜單的打開屬性表選項單擊事件總打開frmAttribute窗口：

private void AttributesToolStripMenuItem_Click(object sender, EventArgs e)
 {
 frmAttribute newFA = new frmAttribute( p_Layer);//傳入圖層，在右擊事件裏返回的圖層
 newFA.Show();
 }

 窗機加載時讀取信息：

private void frmAttribute_Load(object
 
 sender, EventArgs e)
{
 try
 {

 pFeatureLayer = pLayer as IFeatureLayer;
 pFeatureClass = pFeatureLayer.FeatureClass;
 pLayerFields = pFeatureLayer as ILayerFields;
 DataSet ds = new DataSet("dsTest");
 DataTable dt = new DataTable(pFeatureLayer.Name);

 DataColumn dc = null;
 for (int i = 0; i < pLayerFields.FieldCount; i++)
 {
  dc 
 
= new DataColumn(pLayerFields.get_Field(i).Name);

 //if (pLayerFields.get_Field(i).Editable == true)
 // dc.ReadOnly = false;
 //else
 // dc.ReadOnly = true;
 dt.Columns.Add(dc);
 dc = null;
 }

 IFeatureCursor pFeatureCursor = pFeatureClass.Search(null, false);
 IFeature pFeature = pFeatureCursor.NextFeature();
 while (pFeature != null)
 {
  DataRow dr = dt.NewRow();
  for (int j = 0; j < pLayerFields.FieldCount; j++)
  {
  if (pLayerFields.FindField(pFeatureClass.ShapeFieldName) == j)
 {
 dr[j] = pFeatureClass.ShapeType.ToString();
 }
  else
  {
 dr[j] =pFeature.get_Value(j);
  }
  }
  dt.Rows.Add(dr);
  pFeature = pFeatureCursor.NextFeature();
 }
  dataGridView1.DataSource = dt;
  }
  catch (Exception exc)
  {
  MessageBox.Show("讀取屬性表失敗：" + exc.Message);
  this.Dispose();
  }
  finally
  {
 //this.Close();
  }
 }
