添加和删除字段

标签：datagridview   ar   sp   c   r   ad   ef   new   bs   

添加字段用IFeatureClass的AddField 或者 ITable的AddField方法

 private void 添加字段ToolStripMenuItem_Click(object sender, EventArgs e)
        {
          IFeatureLayer pFeatureLayer=  pLayer as IFeatureLayer;
       
          IField field = new FieldClass();
          IFieldEdit fieldEdit = field as IFieldEdit;
          fieldEdit.Name_2 = "Point";
    
          fieldEdit.Type_2 = esriFieldType.esriFieldTypeDouble;
          pFeatureLayer.FeatureClass.AddField(field);
        
          OpenAttribute(); //打开属性表的方法，在这里是起到刷新的作用
        }

删除字段，要先获得删除字段的索引，这里可以从datagridview中获取

 private void 删除字段ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            int index = dataGridView1.CurrentCell.ColumnIndex;//获取列索引
         
            IFeatureLayer pFeatureLayer = pLayer as IFeatureLayer;

           IField field=   pFeatureLayer.FeatureClass.Fields.get_Field(index);
           MessageBox.Show(field.Name);
           pFeatureLayer.FeatureClass.DeleteField(field);
           OpenAttribute();
        }
