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;

}
