使用C#配合ArcGIS Engine进行地理信息系统开发

然后就是获取shpaefile的属性表了，这里我们主要使用 IField、IFeatureCursor、IFeature 这三个接口来达成目标：
接口说明如下：

• IField 接口：用于获取要素表。
• IFeature 接口：用来接收查询出来的要素。
• IFeatureCursor 接口：通过Search进行查询，可以将结果保存在这里，从而利用NextFeature方法，遍历所有要素。

  代码如下：

  
  public void Opentable() 
      { 
        IFields pFields; 
        pFields = pFeaturelayer.FeatureClass.Fields; 
        dataGridView1.ColumnCount = pFields.FieldCount; 
        for (int i = 0; i < pFields.FieldCount; i++) 
        { 
          string fldName = pFields.get_Field(i).Name; 
          dataGridView1.Columns[i].Name = fldName; 
          dataGridView1.Columns[i].ValueType = System.Type.GetType(ParseFieldType(pFields.get_Field(i).Type)); 
        } 
        IFeatureCursor pFeatureCursor; 
        pFeatureCursor = pFeaturelayer.FeatureClass.Search(null, false); 
        IFeature pFeature; 
        pFeature = pFeatureCursor.NextFeature(); 
        while (pFeature != null) 
        { 
          string[] fldValue = new string[pFields.FieldCount]; 
          for (int i = 0; i < pFields.FieldCount; i++) 
          { 
            string fldName; 
            fldName = pFields.get_Field(i).Name; 
            if (fldName == pFeaturelayer.FeatureClass.ShapeFieldName) 
            { 
              fldValue[i] = Convert.ToString(pFeature.Shape.GeometryType); 
            } 
            else 
              fldValue[i] = Convert.ToString(pFeature.get_Value(i)); 
          } 
          dataGridView1.Rows.Add(fldValue); 
          pFeature = pFeatureCursor.NextFeature(); 
        } 
      }
