ArcEngine修改要素類字段別名

對於Geodatabase中的要素類，我們可以對它們的字段別名進行修改。下圖爲數據庫中某要素類的屬性表：

我們現在將Name修改爲Name_1，Code修改爲Code_1，代碼如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using ESRI.ArcGIS.Carto;
using ESRI.ArcGIS.Controls;
using ESRI.ArcGIS.DataSourcesFile;
using ESRI.ArcGIS.DataSourcesGDB;
using ESRI.ArcGIS.Display;
using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.Geodatabase;
using ESRI.ArcGIS.Geometry;
using ESRI.ArcGIS.Output;
using ESRI.ArcGIS.SystemUI;

namespace WindowsFormsApplication1
{
    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }

        private void btnModify_Click(object sender, EventArgs e)
        {
            IWorkspaceFactory pWorkspaceFactory = new FileGDBWorkspaceFactory();
            IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(@"E:\Users\dsf\Desktop\data.gdb", 0);
            IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace;
            IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass("fc");
            ITable pTable = pFeatureClass as ITable;
            IFields pFields = pTable.Fields;
            if (pFields.FindField("Name") != -1)
            {
                IClassSchemaEdit pClassSchemaEdit = pTable as IClassSchemaEdit;
                ISchemaLock pSchemaLock = pTable as ISchemaLock;
                pSchemaLock.ChangeSchemaLock(esriSchemaLock.esriExclusiveSchemaLock);
                pClassSchemaEdit.AlterFieldAliasName("Name", "Name_1");
                pSchemaLock.ChangeSchemaLock(esriSchemaLock.esriSharedSchemaLock);
            }
            if (pFields.FindField("Code") != -1)
            {
                IClassSchemaEdit pClassSchemaEdit = pTable as IClassSchemaEdit;
                ISchemaLock pSchemaLock = pTable as ISchemaLock;
                pSchemaLock.ChangeSchemaLock(esriSchemaLock.esriExclusiveSchemaLock);
                pClassSchemaEdit.AlterFieldAliasName("Code", "Code_1");
                pSchemaLock.ChangeSchemaLock(esriSchemaLock.esriSharedSchemaLock);
            }
        }
    }
}

修改後的結果如下圖所示，需要注意的是：shp文件的字段別名無法修改。’
