好长时间没更新博客了，从含有X,Y,Z的字段数据生成要素类，代码如下：

public IFeatureClass CreateXYEventSource(ITable table, ISpatialReference spatialReference)

{

  IXYEvent2FieldsProperties xyEvent2FieldsProperties = new XYEvent2FieldsPropertiesClass();

  xyEvent2FieldsProperties.XFieldName = "X";

  xyEvent2FieldsProperties.YFieldName = "Y";

  IDataset sourceDataset = (IDataset)table;

  IName sourceName = sourceDataset.FullName;

   IXYEventSourceName xyEventSourceName = new XYEventSourceNameClass();

  xyEventSourceName.EventProperties = xyEvent2FieldsProperties;

  xyEventSourceName.EventTableName = sourceName;

  xyEventSourceName.SpatialReference = spatialReference;

  IName name = (IName)xyEventSourceName;

  IXYEventSource xyEventSource = (IXYEventSource)name.Open();

  IFeatureClass featureClass = (IFeatureClass)xyEventSource;

  return featureClass;

}
