1.AddInEditorExtension
功能描述:编辑器扩展,实现在编辑要素,对编辑事件的监听,及对新创建的要素的处理
核心代码:
void Events_OnStartEditing()
{
//Since features of shapefiles, coverages etc cannot be validated, ignore wiring events for them
if (ArcMap.Editor.EditWorkspace.Type != esriWorkspaceType.esriFileSystemWorkspace)
{
//wire OnCreateFeature Edit event
Events.OnCreateFeature += new IEditEvents_OnCreateFeatureEventHandler(Events_OnCreateChangeFeature);
//wire onChangeFeature Edit Event
Events.OnChangeFeature += new IEditEvents_OnChangeFeatureEventHandler(Events_OnCreateChangeFeature);
}
}
//Invoked at the end of Editor session (Editor->Stop Editing)
void Events_OnStopEditing(bool Save)
{
//Since features of shapefiles, coverages etc cannot be validated, ignore wiring events for them
if (ArcMap.Editor.EditWorkspace.Type != esriWorkspaceType.esriFileSystemWorkspace)
{
//unwire OnCreateFeature Edit event
Events.OnCreateFeature -= new IEditEvents_OnCreateFeatureEventHandler(Events_OnCreateChangeFeature);
//unwire onChangeFeature Edit Event
Events.OnChangeFeature -= new IEditEvents_OnChangeFeatureEventHandler(Events_OnCreateChangeFeature);
}
} void Events_OnCreateChangeFeature(ESRI.ArcGIS.Geodatabase.IObject obj)
{
IFeature inFeature = (IFeature)obj;
if (inFeature.Class is IValidation)
{
IValidate validate = (IValidate)inFeature;
string errorMessage;
//Validates connectivity rules, relationship rules, topology rules etc
bool bIsvalid = validate.Validate(out errorMessage);
if (!bIsvalid)
{
System.Windows.Forms.MessageBox.Show("Invalid Feature\n\n" + errorMessage);
}
else
{
System.Windows.Forms.MessageBox.Show("Valid Feature");
}
}
}

2.AddInExtensionPersist
功能描述:ArcMap扩展,实现对ArcMap事件的监听
比如启动,加载,保存等事件
3.AddInReportManager
功能说明:ESRI自带的一种报表导出方案
主要接口IReportDataSource,IReportTemplate
需要提前做好.rlf文件
4.AddInTimeSeriesGraph
功能描述:折线图 Tool
示例数据路径:C:\Program Files (x86)\ArcGIS\DeveloperKit10.1\Samples\data\StreamflowDateTime
相关接口
IIdentify :Provides access to members that identify features,相关矢量图层
IDisplayTable :Provides access to members that work with the display table associated with a standalone table. 该接口包含Joined 字段
IFeatureLayerDefinition:
ILookupSymbol .LookupSymbol ():Returns a reference to the renderer's symbol for the input feature.查询某个要素的Symbol
IDataGraphWindow2 :Provides access to members that control the DataGraph Window. ESRI自带的专题图窗口,可以使用下述代码调用显示
pDGWin = new DataGraphWindowClass();
pDGWin.DataGraphBase = pDataGraphBase;
pDGWin.Application = ArcMap.Application;
pDGWin.Show(true); pDataGraphs.AddDataGraph(pDataGraphBase);
设置Title,坐标轴显示内容等
pDataGraphT = new DataGraphTClass();
pDataGraphBase = (IDataGraphBase)pDataGraphT; // load template from <ARCGISHOME>\GraphTemplates\
string strPath = null;
strPath = Environment.GetEnvironmentVariable("ARCGISHOME");
try
{
pDataGraphT.LoadTemplate(strPath + @"GraphTemplates\timeseries.tee");
}
catch
{ } // graph, axis and legend titles. Substitute them for different input layer
pDataGraphT.GeneralProperties.Title = "Daily Streamflow for Guadalupe Basin in 1999";
pDataGraphT.LegendProperties.Title = "Monitoring Point";
pDataGraphT.get_AxisProperties().Title = "Streamflow (cfs)";
pDataGraphT.get_AxisProperties().Logarithmic = true;
pDataGraphT.get_AxisProperties().Title = "Date";
pDataGraphBase.Name = layerName;
设置绘图内容:
ISeriesProperties pSP = null;
pSP = pDataGraphT.AddSeries("line:vertical");
pSP.ColorType = esriGraphColorType.esriGraphColorCustomAll;
pSP.CustomColor = pSymbol.Color.RGB;
pSP.WhereClause = whereClause;
pSP.InLegend = true;
pSP.Name = gageID; pSP.SourceData = pLayer;
pSP.SetField(, timefldName);
pSP.SetField(, dataFldName);
IDataSortSeriesProperties pSortFlds = null;
pSortFlds = (IDataSortSeriesProperties)pSP;
int idx = ;
pSortFlds.AddSortingField(timefldName, true, ref idx); pDataGraphBase.UseSelectedSet = true; ITrackCancel pCancelTracker = null;
pCancelTracker = new CancelTracker();
pDataGraphT.Update(pCancelTracker);
其他代码片段:
以下代码实现在检索时,先检测定义查询的Sql语句,如果有内容,则与新的查询语句And,没有,则直接使用新的查询语句
IFeatureLayerDefinition pFeatureLayerDef = null;
pFeatureLayerDef = (IFeatureLayerDefinition)pLayer;
string definitionExpression = null;
definitionExpression = pFeatureLayerDef.DefinitionExpression; string whereClause = null;
if (definitionExpression == "")
whereClause = "[" + gageIDFldName + "] = '" + gageID + "'";
else
whereClause = "[" + gageIDFldName + "] = '" + gageID + "' AND " + definitionExpression;
5.AlgorithmicColorRamp
功能说明:
接口:
IContentsView: Provides access to members that control table of contents views,
Used to manage a contents view. The tabs in ArcMap's Table of Contents (TOC) are examples of a contents view.
示例用法:判断TOC中选中的内容
IContentsView ContentsView = null;
ContentsView = ArcMap.Document.CurrentContentsView;
if (ContentsView is TOCDisplayView)
{
if (ContentsView.SelectedItem is DBNull)
{
//
// If we don't have anything selected.
//
MessageBox.Show("SelectedItem is Null C#." + "Select a layer in the Table of Contents.", "No Layer Selected", MessageBoxButtons.OK, MessageBoxIcon.Information);
return;
}
//
// Get the selected Item.
//
VarSelectedItem = ContentsView.SelectedItem;
//
// Selected Item should implement the IGeoFeatureLayer interface - therefore we
// have selected a feature layer with a Renderer property (Note: Other interfaces
// also have a Renderer property, which may behave differently.
//
if (VarSelectedItem is IGeoFeatureLayer)
{
//....
}
6.AngleAngleConstructor
接口
IEditSketch3:Provides access to members that access and manipulate the edit sketch.
