问题描述：

    需要对一批shp文件读取，提取其中部分字段到数据库

解决方法：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

using OSGeo.GDAL;
using OSGeo.OGR;

namespace learnGDAL
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
         
        private void button1_Click(object sender, EventArgs e)
        {
            Gdal.AllRegister();
            Ogr.RegisterAll();

            OSGeo.GDAL.Gdal.SetConfigOption("GDAL_FILENAME_IS_UTF8", "YES");
            OSGeo.GDAL.Gdal.SetConfigOption("SHAPE_ENCODING", "CP936");

            string shpFilePath = @"E:\GDAL\gdal\learnGDAL\learnGDAL\testdata\110105dp.shp";
            OSGeo.OGR.Driver driver = Ogr.GetDriverByName("ESRI Shapefile");
            DataSource ds = null;
            Layer layer = null;

            
            try
            {
                ds = Ogr.Open(shpFilePath, 0);
                layer = ds.GetLayerByIndex(0);
                //当前shp元素数
                int count = (int)layer.GetFeatureCount(0);

                Feature fe = layer.GetNextFeature();
                while (fe != null)
                {
                    string XZQDM = fe.GetFieldAsString("XZQDM");
                    string TBBH = fe.GetFieldAsString("TBBH");
                    double BZB = fe.GetFieldAsDouble("BZB");
                    double LZB = fe.GetFieldAsDouble("LZB");
                    double TBMJ = fe.GetFieldAsDouble("TBMJ");
                    string TZ = fe.GetFieldAsString("TZ");
                    string YSFNH = fe.GetFieldAsString("YSFNH");

                    label1.Text += TBBH+" "+TZ+"\n";
                    fe = layer.GetNextFeature();
                }
            }
            catch (Exception ex)
            {
            }
            finally
            {
                if (layer != null)
                {
                    layer.Dispose();
                }
                if (ds != null)
                {
                    ds.Dispose();
                }
                driver.Dispose();
            }
        }

        

        
    }
}

其实吧，这个方案也不靠谱。。。

继“CP936”也失效之后重新自定义方法解决GDAL读取SHP乱码问题
