ArcEngine 几何对象录入两种方法说明

  arcEngine 录入数据有2种方式，一种是创建IFeatureBuffer,另一种是采用IWorkspaceEdit接口

 他们的差别在于，第一种是创建一个游标进行操作，而后者则是直接将当前图层签出进行操作，前者被称为史上效率最高的方式

 闲话少说，直接代码：

  Dim pCursor As IFeatureCursor Dim pFeatBuffer As IFeatureBuffer Dim p As IPoint p = New PointClass p.PutCoords(pPoint.X, pPoint.Y) pCursor = pFeatureClass.Insert(True) pFeatBuffer = pFeatureClass.CreateFeatureBuffer pFeatBuffer.Shape = p Dim entry As KeyValuePair(Of String, String) Dim index As Integer For Each entry In dt Dim strKey As String = entry.Key Dim strValue As String = entry.Value If String.IsNullOrEmpty(strValue) Then Continue For End If Try index = pFeatBuffer.Fields.FindField(strKey) If index > 0 Then '将时间字符串转成时间格式. If strKey = "zRksj".ToUpper() Or strKey = "NORGINDATE".ToUpper() Or strKey = "ZENDDATE".ToUpper() Then pFeatBuffer.Value(index) = Date.Parse(strValue) Continue For End If pFeatBuffer.Value(index) = strValue.ToString().Trim() End If Catch ex As ApplicationException Continue For End Try Next index = pFeatBuffer.Fields.FindField("ZYOID") pFeatBuffer.Value(index) = pOid.ToString().Trim() pCursor.InsertFeature(pFeatBuffer) pCursor.Flush() 

Dim we As IWorkspaceEdit Dim pFeature As IFeature Dim p As IPoint Dim index As Integer Dim entry As KeyValuePair(Of String, String) p = New PointClass we = CType(pFeatureClass, IDataset).Workspace we.StartEditing(False) '开始编辑 we.StartEditOperation() ' pFeature = pFeatureClass.CreateFeature() p.PutCoords(pPoint.X, pPoint.Y) pFeature.Shape = p If dt IsNot Nothing Then For Each entry In dt Dim strKey As String = entry.Key Dim strValue As String = entry.Value If String.IsNullOrEmpty(strValue) Then Continue For End If Try index = pFeature.Fields.FindField(strKey) If index > 0 Then '将时间字符串转成时间格式. If strKey = "zRksj".ToUpper() Or strKey = "NORGINDATE".ToUpper() Or strKey = "ZENDDATE".ToUpper() Then pFeature.Value(index) = Date.Parse(strValue) Continue For End If pFeature.Value(index) = strValue.ToString().Trim() End If Catch ex As ApplicationException Continue For Finally End Try Next End If index = pFeature.Fields.FindField("ZYOID") pFeature.Value(index) = pOid.ToString().Trim() pFeature.Store() we.StopEditOperation() ''结束事务 we.StopEditing(True)
