DataGridView中显示shp图层数据
1. 简单点查询
（1）引用
????
using ESRI.ArcGIS.Geodatabase;using ESRI.ArcGIS.DataSourcesFile;using ESRI.ArcGIS.esriSystem;using ESRI.ArcGIS.Geometry;
?
（2）ArcEngine的Licence认证
IAoInitialize m_AoInitialize = new AoInitializeClass(); esriLicenseStatus licenseStatus = esriLicenseStatus.esriLicenseUnavailable; licenseStatus = m_AoInitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeEngine);
?
（3）空间查询或属性查询
OpenFileDialog ofdDBF = new OpenFileDialog();ofdDBF.Filter = "属性表文件(*.dbf)|*.dbf";if (ofdDBF.ShowDialog() == DialogResult.OK){ string OpenFileName = ofdDBF.FileName.Trim(); string dbfFilePath = Path.GetDirectoryName(OpenFileName); string dbfFileName = Path.GetFileName(OpenFileName); IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactoryClass(); IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(dbfFilePath, 0); IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace; if (pFeatureWorkspace != null) { IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(dbfFileName); if (pFeatureClass != null) { DataTable dt = new DataTable(); DataColumn dc = null; for (int i = 0; i < pFeatureClass.Fields.FieldCount; i++) { dc = new DataColumn(pFeatureClass.Fields.get_Field(i).Name); dt.Columns.Add(dc); } IFeatureCursor pFeatureCursor = pFeatureClass.Search(null, false); IFeature pFeature = pFeatureCursor.NextFeature(); DataRow dr = null; while (pFeature != null) { dr = dt.NewRow(); for (int j = 0; j < pFeatureClass.Fields.FieldCount; j++) { if (pFeatureClass.FindField(pFeatureClass.ShapeFieldName) == j) { dr[j] = pFeatureClass.ShapeType.ToString(); } else { dr[j] = pFeature.get_Value(j).ToString(); } } dt.Rows.Add(dr); pFeature = pFeatureCursor.NextFeature(); } dataGridView1.DataSource = dt; } }}?
